description: This dissertation examines the transformation of Tibetan artefacts into fine art. I seek to understand how this transformation originated, why and when it occurred and, most significantly, the value creation processes associated with maintaining artworlds. My original contribution is the analysis of the history of Tibetan art's reception in the west. In essence, I investigate the western commodification of Tibetan art during the twentieth century. The focus of this study is the central locus for this phenomenon, the United States, specifically New York City. Beginning with the premise that the concept of Tibetan art as a fine art is a western construct, I trace the (re)presentation of Tibet and Tibetan culture within the western artworld. The exhibition of Tibetan art by the prestigious New York Asia Society in 1969 exemplified the worthiness of Tibetan artefacts as art and began an 'informational' cascade phenomenon. I argue that the institutionalization of Tibetan art discourse at this exhibition, acknowledged the transforming process. Through observations and critical analysis of primary and secondary material, this dissertation investigates the transformation of Tibetan artefacts into art by means of the value creation processes of art exhibition catalogues and associated New York Asia Week activities - the art auctions and fairs. This analysis found that the recent emphasis on the aestheticization of Tibetan art has generated a burgeoning private demand for museum-quality masterpieces, resulting in anomalies in collecting and exhibiting practices. For instance, the alleged practice of overpainting highlights the over emphasis on aesthetic appreciation, while bringing into question the interrelationship of authority and authenticity. At the same time, the narrative of lost Tibetan culture obscures questions of representation, consuming and ownership.
Floquet engineering of continuous-time quantum walks: towards the simulation of complex and next-to-nearest neighbor couplings

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The formalism of continuous-time quantum walks on graphs has been widely used in the study of quantum transport of energy and information, as well as in the development of quantum algorithms. In experimental settings, however, there is limited control over the coupling coefficients between the different nodes of the graph (which are usually considered to be real-valued), thereby restricting the types of quantum walks that can be implemented. In this work, we apply the idea of Floquet engineering in the context of continuous-time quantum walks, i.e., we define periodically-driven Hamiltonians which can be used to simulate the dynamics of certain target continuous-time quantum walks. We focus on two main applications: i) simulating quantum walks that break time-reversal symmetry due to complex coupling coefficients; ii) increasing the connectivity of the graph by simulating the presence of next-to-nearest neighbor couplings. Our work provides explicit simulation protocols that may be used for directing quantum transport, engineering the dispersion relation of one-dimensional quantum walks or investigating quantum dynamics in highly connected structures.

description: Recently an effective Lagrangian for the interactions of photons, Nambu-Goldstone bosons and superfluid phonons in dense quark matter has been derived using anomaly matching arguments. In this paper we illuminate the nature of certain anomalous terms in this Lagrangian by an explicit microscopic calculation. We also generalize the corresponding construction to introduce the axion field. We derive an anomalous axion effective Lagrangian describing the interactions of axions with photons and superfluid phonons in the dense matter background. This effective Lagrangian, among other things, implies that an axion current will be induced in the presence of magnetic field. We speculate that this current may be responsible for the explanation of neutron star kicks.

description: Sales in the food marketing system rose 3.6 percent because of U.S. economic growth in 1993. Retail food price increases were moderate (2.2 percent). Competition for scarce shelf space, heavy couponing, and record new products were indicators of aggressive competition. The surplus of foreign trade in processed foods rose sharply. The number of merger and leveraged buyout transactions rose, but their value dropped.

description: (Abridged) Aim: We attempt to determine robust estimates of the heliospheric magnetic flux ($Φ_H$) using Parker Solar Probe (PSP) data, analyze how susceptible this is to overestimation compared to the true open flux ($Φ_{open}$), assess its dependence on time and space, and compare it to simple estimates from Potential Field Source Surface (PFSS) models. Methods: We compare different methods of computation using data from PSP, STEREO A and Wind. The effects of fluctuations and large scale structure on the estimate are probed by using measured radial trends to produce synthetic data. Best estimates are computed as a function of time and space, and compared to estimates from PFSS models. Results: Radially-varying fluctuations of the HMF vector and variation of the Parker spiral angle cause the standard metrics of the mean and mode to evolve with radius independent of the central value about which the vector fluctuates. This is best mitigated by projecting the vector into the background Parker spiral direction. Nevertheless, we find a small enhancement in flux close to 1AU. The fraction of locally inverted field lines grows with radial distance from the Sun which remains a possible physical reason for this excess, but is negligible at PSP`s perihelia. Similarly, the impact of fluctuations in general is much reduced at PSP`s perihelia. The overall best estimate is ~2.5 nT AU2 . No strong dependence on latitude or longitude is apparent. The PFSS models predict lower values from 1.2 to 1.8 nT AU2. Conclusions: The heliospheric flux is robustly estimated relative to a mean Parker spiral direction at PSP`s perihelia where the decay of fluctuations and weakening importance of local flux inversions means $Φ_H$ ~ $Φ_{open}$. Despite this, the estimate remains too high to be explained by PFSS models, supporting the idea that coronal models underestimate the open magnetic flux.

description: Sparse linear regression is a vast field and there are many different algorithms available to build models. Two new papers published in Statistical Science study the comparative performance of several sparse regression methodologies, including the lasso and subset selection. Comprehensive empirical analyses allow the researchers to demonstrate the relative merits of each estimator and provide guidance to practitioners. In this discussion, we summarize and compare the two studies and we examine points of agreement and divergence, aiming to provide clarity and value to users. The authors have started a highly constructive dialogue, our goal is to continue it.

title: Cislunar Optimal Robust Trajectory Design With Corrective Maneuvers
Creators: name: Kelly, Scott J.
Publisher: name: Utah State University
Year: 2024

description: One common method for determining how to get from point A to point B is by finding the most fuel-efficient path. This is a common method for spacecraft trajectory designers also. Without any random or unexpected occurrences this path is called the deterministic optimal trajectory. Sometimes unexpected events happen that result in deviating from the most fuel-efficient path; while driving, you may encounter a detour. Naturally, we tend to return to the original fuel-efficient path and continue the journey. Similar deviations happen in space. The rocket delivering a spacecraft to orbit likely will not deliver exactly to the intended starting point of the most fuel-efficient path to the target. As a result, a mid-course correction is required to not miss the target which costs additional fuel. This research seeks to determine the most fuel-efficient path by optimizing the baseline maneuvers in addition to corrections when characterized sources of error exist. This is referred to as a robust optimal trajectory. To determine if the robust path is beneficial, this research compares the total cost of the optimal deterministic trajectory with corrections with the optimal robust trajectory and its associated corrections.
The geometrical origin of the Doppler factor in the Lienard-Wiechert potentials

Subjects: subject: Classical Physics (physics.class-ph)

description: We present an in depth analysis and a new derivation of the Doppler factor in the Lienard-Wiechert potentials, based on geometrical considerations in Minkowski space. We argue that, contrary to a common assumption, the methods used for deriving the Doppler factor in the case of an electrically charged extended particle are not applicable in the case of a point particle. A geometrical interpretation of the Doppler factor is nonetheless found in the later case, based on the electromagnetic interaction model of Fokker. In this model the interaction takes place between infinitesimal worldline segments with end points connected by light signals, just like the points where light pulses are emitted and detected in general. This analogy reveals that the relativistic Doppler effect is the missing link between the classical Doppler effect and the Doppler factor in the Lienard-Wiechert potentials.

Tenure arrangements for facilitating community forestry in British Columbia
Creators: name: Mitchell-Banks, Paul Jonathan
Publisher: name: University of British Columbia
Year: 2009

description: Community forestry is a concept whose time has finally 'come' to British Columbia through a convergence of events including: recommendations from forestry commissions; high profile international conferences and publications on sustainability; increased social awareness of forests and forestry; and greater public pressure for community needs to be addressed. This thesis investigates tenure arrangements to facilitate community forestry in British Columbia. BC forest tenures have evolved over the last century and have timber management biases leading to failures in addressing community forest management concerns. To date, community forestry has not played a significant role in forest management in the province. Community, culture, conflict and planning are highly interrelated concepts and understanding their linkages is essential for successful forest and community planning. Community forestry, which with its long history of success can be an integrated planning tool for sustainable forestry. International community forestry is reviewed, with a particular focus on Sweden which has social and economic similarities to Canada. National and provincial surveys are used to determine the levels of awareness and understanding of community forestry. While offering some advantages, there are limited opportunities to exploit existing tenures due to their industrial focus and continuing policy failures, suggesting a need for new community forest tenures. New community forest tenures offer the opportunity to avoid failures associated with previous tenures and the ability to experiment. Community forestry principles are incorporated with theory, literature and survey information to draft the characteristics of new tenures which offer a more effective and flexible policy vehicle to facilitate community forestry.

description: We explore the origin of stellar metallicity gradients in simulated and observed dwarf galaxies. We use FIRE-2 cosmological baryonic zoom-in simulations of 26 isolated galaxies as well as existing observational data for 10 Local Group dwarf galaxies. Our simulated galaxies have stellar masses between $10^{5.5}$ and $10^{8.6} \msun$. Whilst gas-phase metallicty gradients are generally weak in our simulated galaxies, we find that stellar metallicity gradients are common, with central regions tending to be more metal-rich than the outer parts. The strength of the gradient is correlated with galaxy-wide median stellar age, such that galaxies with younger stellar populations have flatter gradients. Stellar metallicty gradients are set by two competing processes: (1) the steady "puffing" of old, metal-poor stars by feedback-driven potential fluctuations, and (2) the accretion of extended, metal-rich gas at late times, which fuels late-time metal-rich star formation. If recent star formation dominates, then extended, metal-rich star formation washes out pre-existing gradients from the "puffing" process. We use published results from ten Local Group dwarf galaxies to show that a similar relationship between age and stellar metallicity-gradient strength exists among real dwarfs. This suggests that observed stellar metallicity gradients may be driven largely by the baryon/feedback cycle rather than by external environmental effects.

description: Deep learning and the collocation method are merged and used to solve partial differential equations describing structures' deformation. We have considered different types of materials: linear elasticity, hyperelasticity (neo-Hookean) with large deformation, and von Mises plasticity with isotropic and kinematic hardening. The performance of this deep collocation method (DCM) depends on the architecture of the neural network and the corresponding hyperparameters. The presented DCM is meshfree and avoids any spatial discretization, which is usually needed for the finite element method (FEM). We show that the DCM can capture the response qualitatively and quantitatively, without the need for any data generation using other numerical methods such as the FEM. Data generation usually is the main bottleneck in most data-driven models. The deep learning model is trained to learn the model's parameters yielding accurate approximate solutions. Once the model is properly trained, solutions can be obtained almost instantly at any point in the domain, given its spatial coordinates. Therefore, the deep collocation method is potentially a promising standalone technique to solve partial differential equations involved in the deformation of materials and structural systems as well as other physical phenomena.

The model is formulated with the Kogut--Susskind fermion action. We use the chiral condensate as an order parameter to investigate the restoration of the chiral symmetry. The first-order chiral phase transition is clearly observed in the dense region at vanishing temperature with $μ/T\sim O(10^3)$ on a large volume of $V=1024^4$. We also present the results for the equation of state.

description: Using a simple model for nuclear GPDs, we study the role of the neutron contribution to nuclear DVCS observables. As an example, we use the beam-spin asymmetry A_{LU}^A measured in coherent and incoherent DVCS on a wide range of nuclear targets in the HERMES and JLab kinematics. We find that at small values of the momentum transfer t, A_{LU}^A is dominated by the coherent-enriched contribution, which enhances A_{LU}^A compared to the free proton asymmetry A_{LU}^p, A_{LU}^A(ϕ)/A_{LU}^p(ϕ)=1.8-2.2. At large values of t, the nuclear asymmetry is dominated by the incoherent contribution and A_{LU}^A/(ϕ)A_{LU}^p(ϕ)=0.66-0.74. The deviation of A_{LU}^A(ϕ)/A_{LU}^p(ϕ) from unity at large t is a result of the neutron contribution, which gives a possibility to constain neutron GPDs in incoherent nuclear DVCS. A similar trend is expected for other DVCS asymmetries.

Remarks
The otoliths of P. umbonatus are characterized by a large and elliptic ostium and nearly straight cauda, typical of Pterothrissus. These otoliths show a marked ontogenetic change in the development of the ventral area, whose anterior part becomes much deeper in larger specimens. The species can be found in all regions studied here, but is more abundant at the Texas localities (Table 1). In particular, we note that the species also comprised a significant percentage (over 13%) of the Cane River Formation (Louisiana) otolith assemblage (Stringer & Breard 1997). The otoliths show little difference both in time and space. They have a remarkable distribution ranging in age from the middle Eocene to the middle Miocene (Schwarzhans 2010) and can be found at both European and North American localities.

We demonstrate the system supports an obstructed atomic limit phase through the calculation of Wilson loops. Then we characterise the hierarchy of topological boundary modes hosted by the subwavelength array of plasmonic nanoparticles: both one-dimensional edge modes as well as zero-dimensional corner modes. We determine the properties of these modes which robustly confine light at subwavelength scales, calculate the local density of photonic states at edge and corner modes frequencies, and demonstrate the selective excitation of delocalised corner modes in a topological cavity, through non-zero orbital angular momentum beam excitation.

title: Feathered Cocaine: The Misleading Collective Memory of Operation Falcon
Creators: name: Montague, Eric C.
Publisher: name: Utah State University
Year: 2024

description: Operation Falcon (OpFalco) was a seven-year sting that upended the falconry community as numerous cases exposed falcon poaching amidst the sport. At the beginning of OpFalco, the United States Fish and Wildlife Service (FWS) recruited falconer Jeffrey McPartlin as an undercover agent. With McPartlin’s assistance, the FWS compiled hundreds of case files against falconers. By the operation’s culmination in 1984, the FWS had seized hundreds of illegal falcons and indicted 79 people for crimes against wildlife. The federal government ultimately convicted 68 of them, six were acquitted, and seven remain at large to this day after going into hiding.
Although a close, objective investigation of the convictions confirms that crimes against wildlife were committed, the North American Falconers’ Association (NAFA) successfully covered up the sting and created a narrative that framed the government’s actions as an illegitimate attack on falconers. Despite the many convictions, historians have not written about the criminal acts discovered by OpFalco. The written record of OpFalco is one of a bitter battle between the FWS and falconers. Tales of conspiracies fill the pages of pro-falconer writings about OpFalco, while the crimes against the precious falcon resource are erased. OpFalco illuminates the significant impact of the rigorous wildlife management reforms stemming from environmental laws enacted in the 1970s. It provides a critical perspective for analyzing how legislation, conservation efforts, and hunting practices collided and influenced one another. OpFalco, both the operation and its legacy, reflects an era when the FWS chose to test new wildlife laws and dove into a sting, the magnitude of which the agency has never attempted since. The reaction of those targeted by the operation is an exceptional look into the mindset of hunters accustomed to an unregulated continent of bounty as they faced tightening hunting regulations in America during the last quarter of the twentieth century
Forest development, First Nations and distributive justice in Mackenzie Forest District
Creators: name: Dodds, Stephen Walter
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines the emotionally charged relationship between First Nation representatives and the licensee and government stewards of forest development. It provides an overview of the Mackenzie Forest District, its communities, its First Nations, and its stewards. It then discusses the institutional arrangements that constitute the planning and decision-making milieu. Next it provides an historical and a local overview of issues and events that concern First Nation representatives. Turning to principles of distributive justice (elements of political theory that prescribe how resources, opportunity, and power should be distributed among persons) it explains Ronald Dworkin's (1978 & 1985) principle of equal concern and respect, and Joseph Raz's (1986) principle of autonomy. Those principles are then used to support the issues and concerns raised by First Nation representatives and suggest recommendations that could help to mitigate them. The approach taken differs from most forestry theses. Principles of distributive justice, not environmental or ecological principles, are used as a basis for its recommendations, and its focus is on the validity of normative, as opposed to empirical, claims. As I am convinced that many are not aware that good forest stewardship requires the application of rigorous principles of distributive justice, this thesis was written to demonstrate the utility of this approach.
A pre-explosion extended effervescent zone around core collapse supernova progenitors
Creators: name: Soker, Noam
Publisher: name: arXiv
Year: 2020
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: I propose a scenario according to which the dense compact circumstellar matter (CSM) that the ejecta of many core collapse supernovae (CCSNe) collide with within several days after explosion results from a dense zone where in addition to the stellar wind there is gas that does not reach the escape velocity. In this effervescent zone around red supergiant (RSG) stars, there are dense clumps that are ejected from the vicinity of the RSG surface, rise to radii of tens of astronomical units, and then fall back. I consider two simple velocity distributions of the ejected clumps. I find that the density of the bound mass can be tens of times that of the escaping wind, and therefore can mimic a very high mass loss rate. The dense effervescent compact CSM zone can (1) explain the collision of the ejecta of many CCSNe with a dense compact CSM days after explosion, (2) facilitate very high mass loss rate if the star experiences powerful pre-explosion activity, (3) form dust that obscures the progenitor in the visible band, and (4) lead to an efficient mass transfer to a stellar companion at separations of tens of astronomical units, if exists. The effervescent zone might exist for thousands of years and more, and therefore the effervescent CSM model removes the requirement from many type II CCSN progenitors to experience a very strong outburst just years to months before explosion.

description: The present study reports on the structural and magnetic phase transitions in Pr-doped polycrystalline Tb0.6Pr0.4MnO3, using high-resolution neutron powder diffraction (NPD) collected at SINQ spallation source (PSI), to emphasize the suppression of the sinusoidal magnetic structure of pure TbMnO3 and the evolution to a collinear A-type antiferromagnetic ordering. The phase purity, Jahn-Teller distortion, and one-electron bandwidth for eg orbital of Mn3+ cation have been calculated for polycrystalline Tb0.6Pr0.4MnO3, in comparison to the parent materials TbMnO3 and PrMnO3, through the Rietveld refinement study from X-ray diffraction data at room temperature. The temperature-dependent zero field-cooled and field-cooled dc magnetization study at low temperature down to 5 K reveals a variation in the magnetic phase transition due to the effect of Pr3+ substitution at the Tb3+ site, which gives the signature of the antiferromagnetic nature of the sample, with a weak ferromagnetic component at low temperature induced by an external magnetic field. The field-dependent magnetization study at low temperatures gives the weak coercivity having the order of 2 kOe, which is expected due to canted-spin arrangement or ferromagnetic nature of Terbium ordering. The NPD data for Tb0.6Pr0.4MnO3 confirms that the nuclear structure of the synthesized sample maintains its orthorhombic symmetry down to 1.5 K. Also, the magnetic structures have been solved at 50 K, 25 K, and 1.5 K through the NPD study, which shows A-type antiferromagnetic spin arrangement.

Our results characterize BaNi$_2$V$_2$O$_8$ as a two-dimensional (2D) antiferromagnet across the entire temperature range, displaying a series of crossovers from 2D Ising-like to 2D XY and then to 2D Heisenberg behavior with increasing temperature. In particular, the extracted critical exponent of the order parameter reveals a narrow temperature regime close to $T_N$, in which the system behaves as a 2D XY antiferromagnet. Above $T_N$, evidence for Berezinsky-Kosterlitz-Thouless behavior driven by vortex excitations is obtained from the scaling of the correlation length. Our experimental results are in accord with classical and quantum Monte Carlo simulations performed for microscopic magnetic model Hamiltonians for BaNi$_2$V$_2$O$_8$.

description: We prove that if a linear group $Γ\subset \mathrm{GL}_n(K)$ over a field $K$ of characteristic zero is boundedly generated by semi-simple (diagonalizable) elements then it is virtually solvable. As a consequence, one obtains that infinite $S$-arithmetic subgroups of absolutely almost simple anisotropic algebraic groups over number fields are never boundedly generated. Our proof relies on Laurent's theorem from Diophantine geometry and properties of generic elements.

description: We investigate two-dimensional (2D) states of Bose-Einstein condensates (BEC) with self-attraction or self-repulsion, trapped in an axially symmetric optical-lattice potential periodic along the radius. Unlike previously studied 2D models with Bessel lattices, no localized states exist in the linear limit of the present model, hence all localized states are truly nonlinear ones. We consider the states trapped in the central potential well, and in remote circular troughs. In both cases, a new species, in the form of \textit{radial gap solitons}, are found in the repulsive model (the gap soliton trapped in a circular trough may additionally support stable dark-soliton pairs). In remote troughs, stable localized states may assume a ring-like shape, or shrink into strongly localized solitons. The existence of stable annular states, both azimuthally uniform and weakly modulated ones, is corroborated by simulations of the corresponding Gross-Pitaevskii equation. Dynamics of strongly localized solitons circulating in the troughs is also studied. While the solitons with sufficiently small velocities are stable, fast solitons gradually decay, due to the leakage of matter into the adjacent trough under the action of the centrifugal force. Collisions between solitons are investigated too. Head-on collisions of in-phase solitons lead to the collapse; $π$-out of phase solitons bounce many times, but eventually merge into a single soliton without collapsing. The proposed setting may also be realized in terms of spatial solitons in photonic-crystal fibers with a radial structure.

title: Invasion Potential of Nonnative Fishes Through a Large Western Dam Into a Prized and Vulnerable Ecosystem

description: Native river fish face threats from habitat fragmentation, water overallocation, invasive species establishment, and powerful synergies amongst these factors. In the Colorado River Basin, USA, these threats coalesce at Glen Canyon Dam (GCD), which impounds the Colorado River to create Lake Powell, a reservoir inhabited by nonnative fish species. There is widespread concern low water level in Lake Powell may allow nonnative fish to escape through the dam, adversely affecting native fish species downstream in the Grand Canyon. In this study we characterized the seasonal distribution of nonnative fishes in the vicinity of GCD and identified environmental conditions that may lead to increased entrainment and survival of such entrainment, to inform invasion risk into the lower Colorado River (entrainment refers to water and potentially fish drawn into and passed through the GCD hydroelectric infrastructure). When the reservoir was cold, most fishes selected gently sloping habitat such as that found in Wahweap Bay (5 km from GCD), and thus winter entrainment risk is likely minimal for most species. During the summer and fall, fish were  found in the forebay surface waters within meters of the dam, increasing entrainment when the dam penstock (fixed withdrawal structure) is positioned near the surface, as it was during our study, rather than lower as it is at higher water levels.
To evaluate potential injuries to fish during entrainment, we measured conditions of passage through GCD using a pressure sensor and compared our results to previous studies. We estimated members of Centrarchidae (e.g., Smallmouth Bass) may survive entrainment at rates above 50% at low water levels, with survival expected to decrease as the water level rises, but remaining problematically high across all water levels where entrainment is expected. Fish of other families may survive entrainment at higher rates, depending on their physiology. Maintaining water levels higher than those in 2022 and 2023 would decrease both entrainment and survival of entrainment. Under a changing climate the current overallocation of Colorado River water will likely continue to result in conditions suitable for nonnative escapement through CGD, unless and until operational and engineering solutions are implemented.

description: Differences of opinion between people are common in everyday life, but discussing those differences openly in conversation may be unnecessarily rare. We report 3 experiments (N = 1,264 U.S.-based adults) demonstrating that people’s interest in discussing important but potentially divisive topics is guided by their expectations about how positively the conversation will unfold, leaving them more interested in having a conversation with someone who agrees versus disagrees with them. People’s expectations about their conversations, however, were systematically miscalibrated, such that people underestimated how positive these conversations would be—especially in cases of disagreement. Miscalibrated expectations stemmed from underestimating the degree of common ground that would emerge in conversation, and from failing to appreciate the power of social forces in conversation that create social connection. Misunderstanding the outcomes of conversation could lead people to avoid discussing disagreements more often, creating a misplaced barrier to learning, social connection, free inquiry, and free expression.

description: We study the effect of Coulomb interaction between two oppositely doped low-dimensional tJ model systems. We exactly show that, in the one-dimensional case, an arbitrarily weak interaction leads to the formation of charge neutral electron-hole pairs. We then use two different mean-field theories to address the two-dimensional case, where inter-layer excitons also form and condense. We propose that this results in new features which have no analog in single layers, such as the emergence of an insulating spin liquid phase. Our simple bilayer model might have relevance to the physics of doped Mott insulator interfaces and of the new four layer Ba2CaCu4O8 compound.

description: We study the embedding of D7 brane probes in five geometries that are deformations of AdS_5 x S^5. Each case corresponds to the inclusion of quark fields in a dual gauge theory where we are interested in investigating whether chiral symmetry breaking occurs. We use a supersymmetric geometry describing an N=2 theory on its moduli space and a dilaton driven non-supersymmetric flow to establish criteria for a chiral symmetry breaking embedding. We develop a simple spherical D7 embedding that tests the repulsion of the core of the geometry and signals dynamical symmetry breaking. We then use this tool in more complicated geometries to show that an N=2* theory and a non-supersymmetric theory with scalar masses do not induce a chiral condensate. Finally we provide evidence that the Yang Mills* geometry does.

Nonlinear force-free magnetic field extrapolations: comparison of the Grad-Rubin and Wheatland-Sturrock-Roumeliotis algorithm

description: We compare the performance of two alternative algorithms which aim to construct a force-free magnetic field given suitable boundary conditions. For this comparison, we have implemented both algorithms on the same finite element grid which uses Whitney forms to describe the fields within the grid cells. The additional use of conjugate gradient and multigrid iterations result in quite effective codes. The Grad-Rubin and Wheatland-Sturrock-Roumeliotis algorithms both perform well for the reconstruction of a known analytic force-free field. For more arbitrary boundary conditions the Wheatland-Sturrock-Roumeliotis approach has some difficulties because it requires overdetermined boundary information which may include inconsistencies. The Grad-Rubin code on the other hand loses convergence for strong current densities. For the example we have investigated, however, the maximum possible current density seems to be not far from the limit beyond which a force free field cannot exist anymore for a given normal magnetic field intensity on the boundary.

description: We develop a low scale left-right symmetric model based on $SU(3)_C\times SU(2)_L\times SU(2)_R\times U(1)_{B-L}\times Z_2$ with a simplified Higgs sector consisting of only one bidoublet and one $SU(2)_R$ doublet. In this model, the tiny values of light neutrino masses are generated through an inverse-seesaw mechanism. We emphasize that in this setup, the tree-level flavor changing neutral current can be strongly suppressed, consistent with the current experimental constraints. We show that the lightest $CP$-even Higgs boson, which is like the standard model Higgs boson, and the next lightest Higgs boson, $h'$, are generated from the neutral components of the bidoublet. We show that the mass of the next lightest Higgs boson can be of an order a few hundred~\text{GeVs}. We analyze the detection of $h'$ at the Large Hadron Collider (LHC) for a center-of-mass energy $\sqrt{s}=14~\text{TeV}$ and integrated luminosity $L_{\text{int}}=300~{\text{fb}}^{-1}$ via di-Higgs channel: $h'\to hh\to b\bar{b}γγ$ and also in the $ZZ$ channel: $h'\to ZZ\to 4\ell~(\ell=e,~μ)$ at an integrated luminosity $L_{\text{int}}=3000~{\text{fb}}^{-1}$. We consider three benchmark points for this analysis with $m_{h'}=250~\text{GeV},~400~\text{GeV}$, and $600~\text{GeV}$. We show that promising signals with good statistical significances can be obtained in di-Higgs channel, with $2γ+2b$-jets final states.
