description: Moiré flatbands, occurring, e.g., in twisted bilayer graphene at magic angles, have attracted ample interest due to their high degree of experimental tunability and the intriguing possibility of generating novel strongly interacting phases. Here we consider the core problem of Coulomb interactions within fractionally filled spin and valley polarized Moiré flatbands and demonstrate that the dual description in terms of holes, which acquire a nontrivial hole dispersion, provides key physical intuition and enables the use of standard perturbative techniques for this strongly correlated problem. In experimentally relevant examples such as ABC stacked trilayer and twisted bilayer graphene aligned with boron nitride, it leads to emergent interaction-driven Fermi liquid states at electronic filling fractions down to around $1/3$ and $2/3$ respectively. At even lower filling fractions, the electron density still faithfully tracks the single-hole dispersion while exhibiting distinct non-Fermi liquid behavior. Most saliently, we provide microscopic evidence that high temperature fractional Chern insulators can form in twisted bilayer graphene aligned with hexagonal boron nitride.

description: We study analytically the Kondo lattice model with an additional nearest-neighbor antiferromagnetic interaction in the framework of large-N theory. We find that there is a local quantum critical point between two phases, a normal Fermi-liquid and a spin-liquid in which the spins are decoupled from the conduction electrons. The local spin susceptibility displays a power-law divergence throughout the spin liquid phase. We check the reliability of the large-N results by solving by quantum Monte Carlo simulation the N=2 spin-liquid problem with no conduction electrons and find qualitative agreement. We show that the spin-liquid phase is unstable at low temperatures, suggestive of a first-order transition to an ordered phase.

description: This study aims to explore the experience and challenges faced by food delivery riders amidst the COVID-19 pandemic. Employing Interpretative Phenomenological Analysis (IPA) with 10 participatns, results suggest most of their experiences focuses on the importance of self-concept, frustrations, self- esteem, anxiety, burnout, challenges, booking, weather, sanitation, customer, location, and coping mechanisms. Thus, they are having difficulties during the pandemic specially its impact on their psychological states made them urge to strategize and create restrictions on themselves. Furthermore, despite the trials and struggles physically, emotionally and psychologically, these delivery riders always choose to have courage and faith. Moreover, food delivery riders have good self-image after coping with the COVID-19 pandemic.

description: Phosphorus nitride (PN) is the P-bearing species with the highest number of detections in star-forming regions. Multi-line studies of the molecule have shown that the excitation temperature of PN is usually lower than the gas kinetic temperature, suggesting that PN is likely in conditions of sub-thermal excitation. We present an analysis of PN which takes the possible sub-thermal excitation conditions into account in a sample of 24 massive star-forming regions. We observed PN (2-1), (3-2), (4-3), and (6-5) with the IRAM-30m and APEX telescopes and detected PN lines in 15 of them. Together with 9 similar sources detected in PN in previous works, we have analysed the largest sample of star-forming regions to date, made of 33 sources with 24 detections in total (among which 13 are new detections). Hence, we have increased the number of star-forming regions detected in PN by more than a factor 2. Our analysis indicates that the PN lines are indeed sub-thermally excited, but well described by a single excitation temperature. We have compared line profiles and fractional abundances of PN and SiO, a typical shock tracer, and found that almost all objects detected in PN have high-velocity SiO wings. Moreover, the SiO and PN abundances with respect to H2 are correlated over several orders of magnitude, and uncorrelated with gas temperature. This clearly shows that the production of PN is strongly linked to the presence of shocked gas, and rules out alternative scenarios based on thermal evaporation from iced grain mantles.

description: There has been recent interest in conformal twisted boundary conditions and their realisations in solvable lattice models. For the Ising and Potts quantum chains, these amount to boundary terms that are related to duality, which is a proper symmetry of the model at criticality. Thus, at criticality, the duality-twisted Ising model is translationally invariant, similar to the more familiar cases of periodic and antiperiodic boundary conditions. The complete finite-size spectrum of the Ising quantum chain with this peculiar boundary condition is obtained.

description: The tourism industry is amongst the most treasured sources of Egyptian national income, a significant contributor to the country’s gross domestic product (GDP), an indispensable source of foreign exchange earnings as well as a vital source of employment (K Elnagar & Derbali, 2020). However, the tourism industry has experienced a crippling shock by virtue of the detrimental pandemic that is Covid-19. The World Travel and Tourism Council’s annual Economic Impact Report (EIR) discloses that the dramatic fall of Egypt’s Travel and Tourism sector wiped out a stunning $17.6 billion from the nation’s economy in 2020. Accordingly, the sector’s influence on GDP dropped by 55% - EGP505.6bn/ $32.0bn in 2019 (8.8% of total economy), to EGP227.5bn/ $14.4bn in 2020 (3.8% of total economy) (WTTC, 2021).

description: The temperature dependence of the London penetration depth,lambda(T), was measured in both single crystal and polycrystalline MgB_2 samples by a high-resolution, radio frequency technique. A clear exponential temperature dependence of lambda(T) was observed at low temperature, indicating s-wave pairing. A BCS fit to the lowest temperature data gives an in-plane energy gap Delta of 2.6\pm0.2 meV (2Δ/T_c=1.5\pm0.1), which is significantly smaller than the standard BCS weak coupling value of 3.5. We find that the data are best described by a two-gap model.

description: Electrically manipulating the quantum properties of nano-objects, such as atoms or molecules, is typically done using scanning tunnelling microscopes and lateral junctions. The resulting nanotransport path is well established in these model devices. Societal applications require transposing this knowledge to nano-objects embedded within vertical solid-state junctions, which can advantageously harness spintronics to address these quantum properties thanks to ferromagnetic electrodes and high-quality interfaces. The challenge here is to ascertain the device's effective, buried nanotransport path, and to electrically involve these nano-objects in this path by shrinking the device area from the macro- to the nano-scale while maintaining high structural/chemical quality across the heterostructure. We've developed a low-tech, resist- and solvent-free technological process that can craft nanopillar devices from entire in-situ grown heterostructures, and use it to study magnetotransport between two Fe and Co ferromagnetic electrodes across a functional magnetic CoPc molecular layer. We observe how spin-flip transport across CoPc molecular spin chains promotes a specific magnetoresistance effect, and alters the nanojunction's magnetism through spintronic anisotropy. In the process, we identify three magnetic units along the effective nanotransport path thanks to a macrospin model of magnetotransport. Our work elegantly connects the until now loosely associated concepts of spin-flip spectroscopy, magnetic exchange bias and magnetotransport due to molecular spin chains, within a solid-state device. We notably measure a 5.9meV energy threshold for magnetic decoupling between the Fe layer's buried atoms and those in contact with the CoPc layer forming the so-called 'spinterface'. This provides a first insight into the experimental energetics of this promising low-power information encoding unit.

description: To date there is extremely limited knowledge of the economic consequences of post-harvest losses for smallholders in sub-Saharan Africa. Major contributors to economic losses are price penalties for poor quality marketed grain. This study investigates farm-gate level discounts demanded by rural Rwandan bean traders for insect-damaged dry beans. We use a simplified contingent evaluation methodology with physical grain samples to elicit seasonal damage discount schedules, gathering data from 270 trader interviews in 25 regionally-diverse rural markets, in periods of both grain abundance and grain scarcity. We find that while levels of 5-10% grain damage can generally be sold with a moderate discount, grain with 20-30% damage is largely unmarketable. We additionally use a two-stage model to investigate physical and non-physical drivers of buying insect-damaged grain and, if so, the demanded discount intensity. Results indicate that while grain damage levels play a central role, large volume traders penalize damage less while traders in the seed market, storing before re-sale, or purchasing heavily from farmers (vs. other traders) penalize damage significantly more. Findings have helped develop more evidence-based extension programming for the Post-Harvest Task Force of the Rwandan Ministry of Agriculture. Additionally, derived discount coefficients help evaluate the cost-effectiveness of technologies throughout the region which prevent post-harvest damage.

description: We calculate the conductance of a superconductor/ferromagnet (S/F) mesoscopic structure in the dirty limit. First we assume that the ferromagnet exhibits a homogeneous magnetization and consider the case that the penetration of the condensate into the F wire is negligible and the case in which the proximity effect is taken into account. It is shown that if the exchange field is large enough, the conductance below the critical temperature $T_C$, is always smaller than the conductance in the normal state. At last, we calculate the conductance for a F/S structure with a local inhomogeneity of the magnetization in the ferromagnet. We demonstrate that a triplet component of the condensate is induced in the F wire.This leads to a increase of the conductance below $T_C$.

Relevance of soft modes for order parameter fluctuations in the Two-Dimensional XY model

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We analyse the spin wave approximation for the 2D-XY model, directly in reciprocal space. In this limit the model is diagonal and the normal modes are statistically independent. Despite this simplicity non-trivial critical properties are observed and exploited. We confirm that the observed asymmetry for the probability density function for order parameter fluctuations comes from the divergence of the mode amplitudes across the Brillouin zone. We show that the asymmetry is a many body effect despite the importance played by the zone centre. The precise form of the function is dependent on the details of the Gibbs measure, giving weight to the idea that an effective Gibbs measure should exist in non-equilibrium systems, if a similar distribution is observed.

Furthermore we estimate the change in demand for residential water use that results under various climate change scenarios. We find that residential single family water demand for our study area may increase by between 42 and 176 million gallons per year by the end of this century.

description: We present a detailed study of the phase diagram of the Kitaev-Hubbard chain, that is the Kitaev chain in the presence of a nearest-neighbour density-density interaction, using both analytical techniques as well as DMRG. In the case of a moderate attractive interaction, the model has the same phases as the non-interacting chain, a trivial and a topological phase. For repulsive interactions, the phase diagram is more interesting. Apart from the previously observed topological, incommensurate and charge density wave phases, we identify the `excited state charge density wave' phase. In this phase, the ground state resembles an excited state of an ordinary charge density phase, but is lower in energy due to the frustrated nature of the model. We find that the dynamical critical exponent takes the value $z\simeq 1.8$. Interestingly, this phase only appears for even system sizes, and is sensitive to the chemical potential on the edges of the chain. For the topological phase, we present an argument that excludes the presence of a strong zero mode for a large part of the topological phase. For the remaining region, we study the time dependence of the edge magnetization (using the bosonic incarnation of the model). These results further expand the region where a strong zero mode does not occur.

Multiple UHECR Events from Galactic hadron jets

description: We propose a new observational test of top-down source models for the ultra-high-energy cosmic-rays (UHECRs), based on the simultaneous observation of two or more photons from the same Galactic hadron jet. We derive a general formula allowing one to calculate the probability of detecting such `multiple events', for any particular top-down model, once the physical parameters of the associated hadron jets are known. We then apply our results to a generic top-down model involving the decay of a supermassive particle, and show that under reasonable assumptions the next-generation UHECR detectors would be able to detect multiple events on a timescale of a few years, depending on the mass of the top-down progenitor. Either the observation or the non-observation of such events will provide constraints on the UHECR top-down models and/or the physics of hadronization at ultra-high energy.

description: The structure of mid-western corn production is analyzed within the context of a changing structure of the U.S. and global production and marketing systems. Further, the economic role of corn production in mid-western regions is investigated both at the major corn-producing states and an industry level using a combination of a descriptive analysis and an impact analysis. The impact analysis is done using an input-output model. The descriptive analysis by itself cannot be used to draw definitive conclusions regarding the role of the region’s production and marketing systems; thus, in addition to the descriptive analysis, an input-output analysis using IMPLAN is executed to incorporate the interdependence of the production and marketing system with other sectors of the economy by estimating economic multipliers.

description: We show how a superconducting circuit consisting of three identical, non-linear oscillators in series considered in terms of its electrical modes can implement a strong, native three-body interaction among qubits. Because of strong interactions, part of the qubit-subspace is coupled to higher levels. The remaining qubit states can be used to implement a restricted Fredkin gate, which in turn implements a CNOT-gate or a spin transistor. Including non-symmetric contributions from couplings to ground and external control we alter the circuit slightly to compensate, and find average fidelities for our implementation of the above gates above $ 99.5\% $ with operation times on the order of a nanosecond. Additionally we show how to analytically include all orders of the cosine contributions from Josephson junctions to the Hamiltonian of a superconducting circuit.

We present a consistent self-adjoint formulation of the problem of scattering on a finite-range potential, which is based on separation of the configuration space on two, internal and external, segments. The scattering amplitude is expressed in terms of the resolvent of a non-Hermitian operator H. The explicit form of this operator depends both on the radius of separation and the boundary conditions at this place which can be chosen in many different ways. We discuss this freedom and show explicitly that the physical scattering amplitude is, nevertheless, unique though not all choices are equally adequate from the physical point of view. The energy-dependent operator H should not be confused with the non-Hermitian effective Hamiltonian H_{eff} exploited usually to describe interference of overlapping resonances. We apply the developed formalism to a chain of L delta-barriers whose solution is also found independently in a closed form. For a fixed band of L overlapping resonances, the smooth energy dependence of H can be ignored so that complex eigenvalues of the LxL submatrix H_{eff} define the energies and widths of the resonances.We construct H_{eff} for the two commonly considered types of the boundary conditions (Neumann and Dirichlet) for the internal motion. Formation in the outer well of a short-lived doorway state is explicitly demonstrated together with the appearance of L-1 long-lived states trapped in the inner part of the chain.

description: This research used stochastic dominance with respect to a function to evaluate producer preference for cropping systems under uncertainty. Six alternative cropping systems were compared for seven different crops. Many times a producer is familiar a developing market opportunity for a specialty crop and the producer has to make a production decision based on yield uncertainty. This research analyzed by how much alternative crop and bio-energy crop yields would need to change to make a producer indifferent between the most preferred (dominant) cropping system and an alternative cropping system. For the current study, the stochastic dominance results indicate that the change in yield necessary is sufficiently large enough to keep producers from accepting the risk of engaging in alternative crop or bio-energy crop production. The paper concludes with study limitations, which the reader is encouraged to review.

description: Using a scanning tunneling microscope or mechanically controllable break junctions it has been shown that it is possible to control the formation of a wire made of single gold atoms. In these experiments an interatomic distance between atoms in the chain of ~3.6 Angstrom was reported which is not consistent with recent theoretical calculations. Here, using precise calibration procedures for both techniques, we measure length of the atomic chains. Based on the distance between the peaks observed in the chain length histogram we find the mean value of the inter-atomic distance before chain rupture to be 2.6 +/- 0.2 A . This value agrees with the theoretical calculations for the bond length. The discrepancy with the previous experimental measurements was due to the presence of He gas, that was used to promote the thermal contact, and which affects the value of the work function that is commonly used to calibrate distances in scanning tunnelling microscopy and mechanically controllable break junctions at low temperatures.

description: Stress and sleep are linked, and they are important determinants of health. However, our current understanding of this relationship is limited to how people differ from one another (e.g., whether poor sleepers experience higher stress); how changes in stress or sleep can mutually influence one another within a person is still poorly understood. Thus, this thesis examines the daily stress-sleep relationships in everyday life. We found that an individual’s nightly fluctuations in sleep predict higher stress levels the next day. This thesis offers evidence of these daily processes and informs theoretical and practical implications for future research and interventions.

Global mass-preserving solutions for a two-dimensional chemotaxis system with rotational flux components coupled with a full Navier-Stokes equation

description: We study the chemotaxis-Navier-Stokes system \[\left\{\; \begin{aligned} n_t + u\cdot\nabla n &=Δn - \nabla\cdot (nS(x,n,c)\nabla c), &&x\inΩ, t > 0, \\ c_t + u\cdot\nabla c &=Δc - n f(c), && x\in Ω, t > 0, \\ u_t + (u\cdot\nabla) u &=Δu + \nabla P + n \nabla ϕ, \;\;\;\; \nabla\cdot u = 0, && x\inΩ, t > 0 \end{aligned}\right.\tag{$\star$} \] with no-flux boundary conditions for $n$, $c$ in a bounded, convex domain $Ω\subseteq\mathbb{R}^2$ with a smooth boundary, which is motivated by recent modeling approaches from biology for aerobic bacteria suspended in a sessile water drop. We further do not assume the chemotactic sensitivity $S$ to be scalar as is common, but to be able to attain values in $\mathbb{R}^{2\times 2}$, which allows for more complex modeling of bacterial behavior near the boundary. This is seen as a potential source of the structure formation observed in experiments. While there have been various results for scalar chemotactic sensitivities $S$ due to a convenient energy-type inequality and some for the non-scalar case with only a Stokes fluid equation (or other strong restrictions) simplifying the analysis of the third equation in ($\star$) significantly, we consider the full combined case under little restrictions for the system giving us very little to go on in terms of a priori estimates. We nonetheless manage to still achieve sufficient estimates using Trudinger-Moser type inequalities to extend the existence results seen in a recent work by Winkler for the Stokes case with non-scalar $S$ to the full Navier-Stokes case. Namely, we construct a similar global mass-preserving generalized solution for ($\star$) in planar convex domains for sufficiently smooth parameter functions $S$, $f$ and $ϕ$ and only under the fairly weak assumptions that $S$ is appropriately bounded, $f$ is non-negative and $f(0) = 0$.

Galactic Halo Stars in Phase Space :A Hint of Satellite Accretion?

description: The present day chemical and dynamical properties of the Milky Way bear the imprint of the Galaxy's formation and evolutionary history. One of the most enduring and critical debates surrounding Galactic evolution is that regarding the competition between ``satellite accretion'' and ``monolithic collapse''; the apparent strong correlation between orbital eccentricity and metallicity of halo stars was originally used as supporting evidence for the latter. While modern-day unbiased samples no longer support the claims for a significant correlation, recent evidence has been presented by Chiba & Beers (2000,AJ,119,2843) for the existence of a minor population of high-eccentricity metal-deficient halo stars. It has been suggested that these stars represent the signature of a rapid (if minor) collapse phase in the Galaxy's history. Employing velocity- and integrals of motion-phase space projections of these stars, coupled with a series of N-body/Smoothed Particle Hydrodynamic (SPH) chemodynamical simulations, we suggest an alternative mechanism for creating such stars may be the recent accretion of a polar orbit dwarf galaxy.

description: We construct finite- and infinite-dimensional non-relativistic extensions of the Newton-Hooke and Carroll (A)dS algebras using the algebra expansion method, starting from the (anti-)de Sitter relativistic algebra in D dimensions. These algebras are also shown to be embedded in different affine Kac-Moody algebras. In the three-dimensional case, we construct Chern-Simons actions invariant under these symmetries. This leads to a sequence of non-relativistic gravity theories, where the simplest examples correspond to extended Newton-Hooke and extended (post-)Newtonian gravity together with their Carrollian counterparts.

description: Recent experiments have emphasized that our understanding of the interplay of electron correlations and randomness in solids is still incomplete. We address this important issue and demonstrate that particle-hole (ph) symmetry plays a crucial role in determining the effects of disorder on the transport and thermodynamic properties of the half-filled Hubbard Hamiltonian. We show that the low-temperature conductivity decreases with increasing disorder when ph-symmetry is preserved, and shows the opposite behavior, i.e. conductivity increases with increasing disorder, when ph-symmetry is broken. The Mott insulating gap is insensitive to weak disorder when there is ph-symmetry, whereas in its absence the gap diminishes with increasing disorder.

description: We study the correlations of classical hardcore dimer models doped with monomers by Monte Carlo simulation. We introduce an efficient cluster algorithm, which is applicable in any dimension, for different lattices and arbitrary doping. We use this algorithm for the dimer model on the square lattice, where a finite density of monomers destroys the critical confinement of the two-monomer problem. The monomers form a two-component plasma located in its high-temperature phase, with the Coulomb interaction screened at finite densities. On the triangular lattice, a single pair of monomers is not confined. The monomer correlations are extremely short-ranged and hardly change with doping.

description: While the role of risks in technology adoption is a classical topic, its effects beyond adoption have not been examined well enough despite that dis-adoption of a technology is also common. This paper examines the role of risk preferences and an exogenous shock on the survival of farmers for a case of export pineapple industry in Ghana. Employing hazard analyses, we find that risk preferences indeed matter for survival and the hazard of exit increased significantly in the period after the occurrence of the exogenous shock. We also find that education has an effect of increasing the resilience of farmers against risks.
