Summary: In this study, the dynamic magnetic behaviors of a ferrimagnetic mixed spin-1 and spin-3/2 Ising ladder-type graphene nanoribbon under a time-dependent magnetic field were analyzed using Monte Carlo simulation. The impact of various factors on the magnetic properties and hysteresis behaviors of the system was investigated, revealing the possibility of double-loop hysteresis behavior under certain parameters.

Summary: A major challenge in simulating glassy systems is how to generate equilibrium configurations at sufficiently low temperatures. This study explores the possibility of using mechanical shear deformation to generate low energy configurations in a model glass former. The results show that shear deformation can induce faster relaxation to low energy configurations at low temperatures, but does not speed up the relaxation process at temperatures where steady state can be reached.

Summary: The study reveals new properties of the quantum spin Hall insulating state, paving the way for superconductivity through the condensation of skyrmions. Through simulations, it is confirmed that there is a direct transition between the quantum spin Hall insulator and an s-wave superconductor, with the ability to analyze dopings away from half-filling. This route to superconductivity has been proposed in the realm of twisted bilayer graphene.

Summary: The study investigates the relationship between one-dimensional molecular chains with two single-particle degenerate states, establishes a connection with the Ising model with phononic interactions, and explores the properties of the model using a transfer-matrix method. The role of state degeneracy and phononic interactions is explicitly stated, and the existence of two peaks in the specific heat capacity behavior is demonstrated.

Summary: This study investigates the relationship between the phases of two-dimensional convex hard superellipse particles and particle shape parameters through computer simulations. By analyzing various shapes including disks, ellipses, squares, rectangles, and rhombuses, as well as shapes with non-uniform curvature, the researchers identify key shape properties that determine liquid crystal and crystalline phases. The results provide design rules for particle shapes to achieve specific two-dimensional microstructures.

Summary: In this paper, a new estimator in the variational Monte Carlo framework is proposed, which utilizes numerically cheap single-core subsamplings to improve the estimation of molecular properties. Furthermore, a spin-dependent core definition is introduced to simplify the algorithm and enhance its efficiency.

Summary: We present the first measurements of deep inelastic scattering spin-dependent azimuthal asymmetries in back-to-back dihadron electroproduction. The observed nonzero sin Delta phi modulations indicate significant correlations between the spin and transverse momenta of hadrons produced in the target- and current-fragmentation regions. These asymmetries provide access to a previously unexplored leading-twist spin-and transverse-momentum-dependent fracture function, offering a new avenue for studying nucleonic structure and hadronization.

Summary: We investigated the thermodynamic properties of magnetic dipolar spin ice on a 2D pentagonal Cairo lattice. We found two explicit temperature peaks, where the low-temperature peak is caused by long-range interactions and the high-temperature peak is associated with the melting of spin ice. The choice of the dipole-dipole interaction radius significantly affects the statistical properties of the model.

Summary: This study further explores systems in contact with multiple baths of different temperatures, considering their thermalization behavior. By using thermodynamic integration, the stationary distribution can be recovered based on measurements from a 'multi-reversible' transformation. The research shows that the system at each step can be described by a generalization of the Boltzmann-Gibbs distribution.

Summary: In this study, a Monte Carlo model is developed to investigate the fluctuating Rashba parameter in spintronic nanodevices. The results reveal that the local E-field of heavy dopants is the origin of the fluctuation. The study also analyzes the influence of lattice size, doping condition, E-field screening, exchange interaction, and temperature on the Rashba interaction in nanomaterials. The research provides insights into the behavior of the Rashba effect and proposes a method to enhance the Rashba interaction through proximity coupling.

Summary: In this study, the thermal and ferroelectric properties of a higher spin (o-=1) Ising thin film in a transverse field were analyzed using the Quantum Monte Carlo method. The physical quantities of longitudinal polarization, pyroelectric coefficient, internal energy, and entropy change were examined in detail. The contribution of the transverse field SL/J and surface coupling Js/J on these physical quantities, with significant implications on phase transition temperature Tc, were revealed. A typical ferroelectric-paraelectric phase transition with hysteresis behavior was observed.
