description: The recent successful experimental observation of quantum anomalous Hall effect in graphene under laser irradiation demonstrates the feasibility of controlling single particle band structure by lasers. Here we study superconductivity in a Hubbard honeycomb model in the presence of an electromagnetic drive. We start with Hubbard honeycomb model in the presence of an electromagnetic field drive, both circularly and linearly polarized light and map it onto a Floquet $t$-$J$ model. We explore conditions on the drive under which one can induce superconductivity (SC) in the system. We study the Floquet $t$-$J$ model within the mean-field theory in the singlet pairing channel and explore superconductivity for small doping in the system using the Bogoliubov-de Gennes approach. We uncover several superconducting phases, which break lattice or time reversal symmetries in addition to the standard $U(1)$ symmetry. We show that the unconventional chiral SC order parameter ($d \pm id$) can be driven to a nematic SC order parameter ($s+d$) in the presence of a circularly polarized light. The $d+id$ SC order parameter breaks time reversal symmetry and is topologically nontrivial, and supports chiral edge modes. We further show that the three-fold nematic degeneracy can be lifted using linearly polarized light. Our work, therefore, provides a generic framework for inducing and controlling SC in the Hubbard honeycomb model, with possible application to graphene and other two-dimensional materials.

Charged-current and neutral-current event fraction determination based on fit vertices, time residuals and PMT hit angles for the Sudbury Neutrino Observatory
Creators: name: Nally, Christian Winslow
Publisher: name: University of British Columbia
Year: 2009

description: The Sudbury Neutrino Observatory (SNO) aims to improve our understanding of neutrinos and energy-generating processes in the Sun. The central purpose of SNO is to compare the flux of charged-current (CC) and neutral-current (NC) events caused by solar neutrinos. The target in SNO will be 10⁶ kg of D₂O. One plan for enhancing the detection of NC events is by doping the D₂O with ³⁵Cl. This thesis describes maximum likelihood fitters created for the purpose of fitting CC events and for fitting NC events that result from neutron capture by a ³⁵Cl nucleus. For each fit event, likelihood ratios are extracted from these fitters to aid in determining the fraction of each type of event in a data set of unknown mixture. It is concluded that using both timing and angle information marginally improves the ability to discriminate between CC and NC events, compared with using angle information alone. This is seen in the reduced estimated error for a technique that determines the CC event fraction in a 50/50 mixed set of CC and NC events. For prototype sets with 2000 events each, and a mixed set with 950 of each event type, an event fraction determination based on only angle information produces a fraction estimate of 0.494 ± 0.037. With identically sized data sets, an event fraction determination that includes both timing and hit angle information produces and estimate of 0.493 ± 0.034.

description: Currently there are two main techniques for independently determining the ages of stellar populations: main sequence evolution theory (via cluster isochrones) and white dwarf cooling theory. Open clusters provide the ideal environment for the calibration of these two clocks. Because current techniques to derive cluster ages from white dwarfs are observationally challenging, we discuss the feasibility of determining white dwarf ages from the brighter white dwarfs alone. This would eliminate the requirement of observing the coolest (i.e., faintest) white dwarfs. We discuss our method for testing this new idea, as well as the required photometric precision and prior constraints on metallicity, distance, and reddening. We employ a new Bayesian statistical technique to obtain and interpret results.

description: Aftershock cascades are a characteristic feature of natural seismicity, but underlying mechanisms remain debated. Here, we experimentally explore the presence or absence of aftershocks during failure of intact rock and slip on newly created laboratory faults. We show that the overall activity increase and spatial localization of acoustic emission (AE) events during fracture nucleation occurs without temporal (Omori-type) correlations. Our analysis shows that this absence of aftershock sequences occurs even beyond peak stress and also when a macroscopic fracture has formed post peak-stress and propagates. Instead, aftershock triggering does occur during post-fracture stress relaxation along the newly created lab-fault and in the presence of large-scale stress heterogeneities, for example, imposed by a saw-cut notch. The detected aftershocks in these cases can be described by standard seismological relationships such as a modified Omori-Utsu relation and its associated inter-event time distribution and productivity relation. Moreover, AE within all experiments follow the Gutenberg-Richter relation, with smaller b-values for triggered events compared to non-triggered events. Performing full-moment tensor inversions, we find that seismic events with significant isotropic, compaction components play an important role for aftershock triggering. The resulting triggered events tend to have focal mechanisms similar to their trigger. Seismic events with predominant tensile components, on the other hand, show little evidence for aftershock triggering. This opens up a new perspective on aftershocks, going beyond not only the rate-and-state paradigm limited to purely frictional sliding or shear events but also the mainshock attribute paradigm where mainshock attributes control aftershock patterns.

description: Background: Struvite, biochar and ash products (collectively known as STRUBIAS) derived from different waste streams are used as fertilisers in agriculture. Raw dairy processing sludge (DPS) shows promise as bio-based fertilisers, but secondary STRUBIAS-derived products need further testing as fertilisers.Aims: The objective of this study was to calculate the phosphorus mineral fertiliser equivalency (P-MFE) for some STRUBIAS products derived from DPS.Methods:Ryegrass (Lolium perenne L.) and wheat (Triticum aestivum) pot trials were used to determine the P-MFE using the apparent P recovery (APR) method for Fe-DPS and DPS-derived struvites (Struvite 1–4), hydrochars (HC1–3) and ash.Results: The tested STRUBIAS products can be divided into two groups: (1) a range of products that can (i.e. Struvite 1–3) and (2) cannot (i.e. Struvite 4, HC1–3, ash and Fe-DPS) be considered fertilisers. In the first group, the P-MFE ranged from 66.8% to 76.7% for ryegrass and from 77.9% to 93.5% for spring wheat grain. In the second group, the P-MFE ranged from 7.8% to 58.3% for ryegrass and from −34.5% to −151.3% for spring wheat grain. The negative agronomic effects of some products for wheat grain (struvite and HC) in this study were mainly caused by high Fe content, which could be overcome by improved treatment processes.Conclusions: Future policy and research must be aware that not all the DPS-derived STRUBIAS products are suitable as fertilisers and therefore need to be tested individually.

description: Phase change memory (PCM) is a rapidly growing technology that not only offers advancements in storage-class memories but also enables in-memory data storage and processing towards overcoming the von Neumann bottleneck. In PCMs, the primary mechanism for data storage is thermal excitation. However, there is a limited body of research regarding the thermal properties of PCMs at length scales close to the memory cell dimension and, thus, the impact of interfaces on PCM operation is unknown. Our work presents a new paradigm to manage thermal transport in memory cells by manipulating the interfacial thermal resistance between the phase change unit and the electrodes without incorporating additional insulating layers. Experimental measurements show a substantial change in thermal boundary resistance as GST transitions from one crystallographic structure (cubic) to another (hexagonal) and as the thickness of tungsten contacts is reduced from five to two nanometers. Simulations reveal that interfacial resistance between the phase change unit and its adjacent layer can reduce the reset current for 20 and 120 nm diameter devices by up to ~40% and ~50%, respectively. The resultant phase-dependent and geometric effects on thermal boundary resistance dictate that the effective thermal conductivity of the phase change unit can be reduced by a factor of four, presenting a new opportunity to reduce operating currents in PCMs.

description: We study dust attenuation and stellar mass of $\rm z\sim 0.6$ star-forming galaxies using new SWIRE observations in IR and GALEX observations in UV. Two samples are selected from the SWIRE and GALEX source catalogs in the SWIRE/GALEX field ELAIS-N1-00 ($Ω= 0.8$ deg$^2$). The UV selected sample has 600 galaxies with photometric redshift (hereafter photo-z) $0.5 \leq z \leq 0.7$ and NUV$\leq 23.5$ (corresponding to $\rm L_{FUV} \geq 10^{9.6} L_\sun$). The IR selected sample contains 430 galaxies with $f_{24μm} \geq 0.2$ mJy ($\rm L_{dust} \geq 10^{10.8} L_\sun$) in the same photo-z range. It is found that the mean $\rm L_{dust}/L_{FUV}$ ratios of the z=0.6 UV galaxies are consistent with that of their z=0 counterparts of the same $\rm L_{FUV}$. For IR galaxies, the mean $\rm L_{dust}/L_{FUV}$ ratios of the z=0.6 LIRGs ($\rm L_{dust} \sim 10^{11} L_\sun$) are about a factor of 2 lower than local LIRGs, whereas z=0.6 ULIRGs ($\rm L_{dust} \sim 10^{12} L_\sun$) have the same mean $\rm L_{dust}/L_{FUV}$ ratios as their local counterparts. This is consistent with the hypothesis that the dominant component of LIRG population has changed from large, gas rich spirals at z$>0.5$ to major-mergers at z=0. The stellar mass of z=0.6 UV galaxies of $\rm L_{FUV} \leq 10^{10.2} L_\sun$ is about a factor 2 less than their local counterparts of the same luminosity, indicating growth of these galaxies. The mass of z=0.6 UV lunmous galaxies (UVLGs: $\rm L_{FUV} > 10^{10.2} L_\sun$) and IR selected galaxies, which are nearly exclusively LIRGs and ULIRGs, is the same as their local counterparts.

description: The confinement of elementary excitations induces distinctive features in the non-equilibrium quench dynamics. One of the most remarkable is the suppression of entanglement entropy which in several instances turns out to oscillate rather than grow indefinitely. While the qualitative physical origin of this behavior is clear, till now no quantitative understanding away from the field theory limit was available. Here we investigate this problem in the weak quench limit, when mesons are excited at rest, hindering entropy growth and exhibiting persistent oscillations. We provide analytical predictions of the entire entanglement dynamics based on a Gaussian approximation of the many-body state, which captures numerical data with great accuracy and is further simplified to a semiclassical quasiparticle picture in the regime of weak confinement. Our methods are valid in general and we apply explicitly to two prototypical models: the Ising chain in a tilted field and the experimentally relevant long-range Ising model.

description: Chromium thiophosphate (CrPS4), a monoclinic crystal of C_2^3 space group, is a ternary layered semiconductor with an optical bandgap of 1.4 eV and exhibits antiferromagnetism below 36 K. Despite its potential in optoelectronic and magnetic applications, the symmetry of its lattice vibrations has not been systematically studied. In this work, we performed a polarized Raman spectroscopy of bulk CrPS4 using three different excitation wavelengths of 457, 514, and 633 nm. High-quality crystals grown by the chemical vapor transport method were mechanically exfoliated or polished to expose three orthogonal crystallographic facets. Polarized Raman spectra were obtained in parallel and cross configurations by rotating samples about the surface normal to each of the facets. Among 33 Raman active modes (16 A and 17 B) at the Brillouin zone center, 19 (8) peaks observed in the parallel (cross) configuration were assigned as A (B) modes. Complex-valued Raman tensors were determined for 7 major A modes using the angle-dependent Raman spectra of the three facets. The results can also be used in determining the crystallographic orientations of CrPS4 unequivocally.

description: The static and dynamic properties of the anisotropic XY-model $(s=1/2)$ on the inhomogeneous periodic chain, composed of $N$ cells with $n$ different exchange interactions and magnetic moments, in a transverse field $h,$ are determined exactly at arbitrary temperatures. The properties are obtained by introducing the Jordan-Wigner fermionization and by reducing the problem to a diagonalization of a finite matrix of $nth$ order. The quantum transitions are determined exactly by analyzing, as a function of the field, the induced magnetization $1/n\sum_{m=1}^{n}μ_{m}\left< S_{j,m}^{z}\right>$ ($j$ denotes the cell, $m$ the site within the cell, $μ_{m}$ the magnetic moment at site $m$ within the cell) and the spontaneous magnetization $1/n\sum_{m=1}^{n}\left< S_{j,m}^{x},\right>$ which is obtained from the correlations $\left< S_{j,m}^{x}S_{j+r,m}^{x}\right>$ for large spin separations. These results, which are obtained for infinite chains, correspond to an extension of the ones obtained by Tong and Zhong(\textit{Physica B} \textbf{304,}91 (2001)). The dynamic correlations, $\left< S_{j,m}^{z}(t)S_{j^{\prime},m^{\prime}}^{z}(0)\right>$, and the dynamic susceptibility, $χ_{q}^{zz}(ω),$ are also obtained at arbitrary temperatures. Explicit results are presented in the limit T=0, where the critical behaviour occurs, for the static susceptibility $χ_{q}^{zz}(0)$ as a function of the transverse field $h$, and for the frequency dependency of dynamic susceptibility $χ_{q}^{zz}(ω)$.

description: It is now clear that a significant population of accreting black holes are undetected by commonly employed optical, mid-infrared color, X-ray, and radio selection methods due to obscuration or contamination of the emission from the nuclear region caused by star formation in the host galaxy. These elusive active galactic nuclei (AGNs) are an important component of the AGN population. They are often found in mergers, where significant black hole growth likely takes place, and in the lowest mass galaxies or galaxies that lack classical bulges, a demographic that places important constraints on models of supermassive black hole seed formation and merger-free models of AGN fueling. In this work, we demonstrate the power of James Webb Space Telescope (JWST) in uncovering and characterizing these elusive AGNs. We present an integrated modeling approach in which both the line and emergent continuum is predicted from gas exposed to the ionizing radiation from a young starburst and an AGN, focusing specifically on the spectral diagnostics available through JWST, and provide predictions on the detectability of key diagnostic lines by the NIRSpec and MIRI spectrometers, assuming typical conditions for the gas. We demonstrate the crucial need for JWST in uncovering low level accretion activity even in nearby galaxies and out to redshifts of ~ 1 - 3, depending on the ionization parameter, and gas phase metallicity. We present a redshift-dependent selection strategy that can be used to identify promising elusive AGN candidates for future follow-up study. The full suite of simulations are available online, where users can select specific parameters and retrieve the predicted continuum and infrared line luminosities from our models.

Sheathed cold-formed steel wall systems
Creators: name: Kyprianou, Constantinos
Publisher: name: Imperial College London

description: Cold-formed steel members are widely used in the construction industry due to their versatility, high strength-to-weight ratio and ease of assembly. Stud columns set in tracks, form the main members in cold-formed steel wall systems, which are typically sheathed with plasterboard or oriented strand board (OSB). The interaction between the cold-formed steel members and the sheathing, which can have a significant effect on the ultimate strength and flexural stiffness due to composite action and bracing, is currently not systematically taken into consideration in design. More than 100 material and connection component tests have been performed to study the behaviour of plasterboard and OSB and their interconnection with cold-formed steel through screws acting in shear and tension. The obtained test results, along with a collected dataset totalling more than 400 physical tests, were used to develop analytical models to describe their load-deformation behaviour; these are suitable for use in numerical simulations and advanced design methods. A total of 17 full-scale sheathed wall stud tests were also performed, with varying connector spacing between either plasterboard or OSB sheathing panels and the steel members. Tests were performed under pure compression, pure bending and combined loading. Reducing the spacing of the connectors from 600 mm to 75 mm resulted in up to 30% increase in capacity while also preventing pull-through connector failure for specimens sheathed with plasterboard. Sophisticated finite element models of wall studs were also developed, which, following successful validation against test results, allowed parametric studies to be undertaken, where the influence of the sheathing, connector spacing and section depth was investigated. Finally, a preliminary design guidance has been developed, where the beneficial effects of bracing, composite action and enhanced boundary conditions at the member ends are recognised, thus enabling more efficient design of sheathed cold-formed steel wall systems.

description: We describe a simple real space renormalization group technique for two dimensional classical lattice models. The approach is similar in spirit to block spin methods, but at the same time it is fundamentally based on the theory of quantum entanglement. In this sense, the technique can be thought of as a classical analogue of DMRG. We demonstrate the method - which we call the tensor renormalization group method - by computing the magnetization of the triangular lattice Ising model.

Generation of all-to-all connections in a two-dimensional qubit array with two-body interactions

description: All-to-all connections are required in general quantum annealing machines to solve various combinatorial optimization problems. The Lechner, Hauke, and Zoller (LHZ) method, which is used to realize the all-to-all connections, requires many-body interactions in locally connected qubits. Because most of the qubit interactions are two-body interactions, Lechner also proposed the construction of each four-body interaction by six controlled-NOT (CNOT) gates between two qubits. However, it is difficult to construct many CNOT gates. Herein, we show more concrete sequences to produce four-body and three-body interactions based on a two-dimensional solid-state qubit system. We show that the number of operations needed to construct the many-body interactions can be reduced using appropriate pulse sequences. These findings will help reduce quantum computation costs for solving combinatorial problems.

description: We establish a connection between the cascading of gluon momenta modeled with the diffusive approximation of the Balitsky-Fadin-Kuraev-Lipatov kernel and the thermodynamics of directed polymers on a tree with disorder. Using known results on the low-temperature spin-glass phase of this statistical-mechanic problem we describe the dynamical phase space of gluon transverse momenta near saturation including its fluctuation pattern. It exhibits a nontrivial clustering structure, analoguous to ``hot spots'', whose distributions are derived and possess universal features in common with other spin-glass systems.

description: We present the results of a deep Hubble Space Telescope (HST) exposure of the nearby globular cluster NGC6397, focussing attention on the cluster's white dwarf cooling sequence. This sequence is shown to extend over 5 magnitudes in depth, with an apparent cutoff at magnitude F814W=27.6. We demonstrate, using both artificial star tests and the detectability of background galaxies at fainter magnitudes, that the cutoff is real and represents the truncation of the white dwarf luminosity function in this cluster. We perform a detailed comparison between cooling models and the observed distribution of white dwarfs in colour and magnitude, taking into account uncertainties in distance, extinction, white dwarf mass, progenitor lifetimes, binarity and cooling model uncertainties. After marginalising over these variables, we obtain values for the cluster distance modulus and age of μ_0 = 12.02 \pm 0.06 and T_c = 11.47 \pm 0.47Gyr (95% confidence limits). Our inferred distance and white dwarf initial-final mass relations are in good agreement with other independent determinations, and the cluster age is consistent with, but more precise than, prior determinations made using the main sequence turnoff method. In particular, within the context of the currently accepted ΛCDM cosmological model, this age places the formation of NGC6397 at a redshift z=3, at a time when the cosmological star formation rate was approaching its peak.

description: Abstract

Spirituality is a life-giving and motivating force, an energy that inspires a person towards a certain goal or a goal beyond individuality. The purpose of this research is to investigate the effect of spirituality at work on knowledge and job performance along with the moderating effect of job engagement and Workplace violence. The research is a descriptive survey study in which 132 professors and employees of Payame Noor University of Tehran participated. The data were analyzed using path analysis test and SPSS 23 and Lisrel 8.75 software. The results of the research indicate that organizations that have spirituality can increase job engagement and reduce withdrawal behavior by creating motivation, providing information and delegating authority, and provide opportunities for empowering and improving the performance of employees.
How Resonances can synchronise with Thresholds

Publisher: name: arXiv
Year: 2008
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The mechanism by which a threshold may capture a resonance is examined. It involves a threshold cusp interfering constructively with either or both (i) a resonance produced via confinement, (ii) attractive t- and u-channel exchanges. The fo(980), X(3872) and Z(4430) are studied in detail. The fo(980) provides a valuable model of the locking mechanism. The X(3872) is too narrow to be fitted by a cusp, and requires either a resonance or virtual state. The Z(4430) can be fitted as a resonance but also can be fitted successfully by a cusp with no nearby resonant pole.

The thermodynamic behaviour of super-cooled water
Creators: name: Jeffery, Christopher A.
Publisher: name: University of British Columbia
Year: 2009

description: A new statistical-mechanical, analytical equation of state for water is developed based on the Song and Mason equation of state and Poole et al.'s simple model of the free energy of open tetrahedral hydrogen bonds. Following Weeks et al. (1971b,a) the intermolecular potential is divided at its minimum into regions of attractive and repulsive force. Repulsive forces are modelled accurately using the algorithm of Ihm et al. (1991), and the attractive forces are modelled by (non-open tetrahedral) hydrogen bonds that contribute both energy and entropy to the free energy of water. Open tetrahedral hydrogen bonds are modeled explicitly using a simplified partition function. The resulting equation of state is 20 to 30 times more accurate than any equivalent simple cubic equation of state over a wide range of pressures (0.1 -» 3000 bar) and temperatures (—34 —> 1200 °C) including the supercooled region. A further extension of the equation of state down to virtually 0 K is possible because of its strong statistical-mechanical basis. The new equation of state predicts a second liquid-liquid critical point at pc — 101 kbar, pc> = 1.03 (g cm- 3 ) and Tc = 222.5 K. A liquid-liquid spinodal bounds a region in which a low-density (p « 0.93 g cm- 3 ), open tetrahedrally bonded liquid and a high-density (p w 1.1 —> 1.5 g cm- 3 ) liquid may exist. A detailed analysis of the physics of homogeneous nucleation using the density and entropy of water calculated from the new equation of state reveals that the homogeneous nucleation temperature above 1 kbar is determined solely by a high-density —> low-density phase transition.

Shape-induced phenomena in the finite size antiferromagnets

description: It is of common knowledge that the direction of easy axis in the finite-size ferromagnetic sample is controlled by its shape. In the present paper we show that a similar phenomenon should be observed in the compensated antiferromagnets with strong magnetoelastic coupling. Destressing energy which originates from the long-range magnetoelastic forces is analogous to demagnetization energy in ferromagnetic materials and is responsible for the formation of equilibrium domain structure and anisotropy of macroscopic magnetic properties. In particular, crystal shape may be a source of additional uniaxial magnetic anisotropy which removes degeneracy of antiferromagnetic vector or artificial 4th order anisotropy in the case of a square cross-section sample. In a special case of antiferromagnetic nanopillars shape-induced anisotropy can be substantially enhanced due to lattice mismatch with the substrate. These effects can be detected by the magnetic rotational torque and antiferromagnetic resonance measurements.

description: We present high quality bi-concave 2D focusing diamond x-ray lenses of apex-radius $R=100~μ$m produced via laser-ablation and improved via a mechanical polishing process. Both for polished and unpolished individual lenses and for stacks of 10 lenses, we show the remaining figure errors determined using x-ray speckle tracking and compare these results to those of commercial $R=50~μ$m beryllium lenses that have similar focusing strength and physical aperture. For two stacks of 10 diamond lenses (polished and unpolished) and a stack of 11 beryllium lenses, we present measured 2D beam profiles out of focus and wire scans to obtain the beam size in the focal plane. These results are complemented with small angle x-ray scattering (SAXS) measurements of a polished and an unpolished diamond lens. Again, we compare this to the SAXS of a beryllium lens. The polished x-ray lenses show similar figure errors to commercially available Be lenses. While the beam size in the focal plane is comparable with that of the Be lenses, the SAXS signal of the polished diamond lenses is considerably lower.

description: We present a short review of possible applications of the Wheeler-De Witt equation to cosmological models based on the low-energy string effective action, and characterised by an initial regime of asymptotically flat, low energy, weak coupling evolution. Considering in particular a class of duality-related (but classically disconnected) background solutions, we shall discuss the possibility of quantum transitions between the phases of pre-big bang and post-big bang evolution. We will show that it is possible, in such a context, to represent the birth of our Universe as a quantum process of tunneling or "anti-tunneling" from an initial state asymptotically approaching the string perturbative vacuum.
