Summary: In an attempt to develop a realistic and theoretically tractable reference fluid for non-associating fluids, a Lennard-Jones-like model with a short-range attractive part was constructed and studied. The model's phase diagram, structure, and thermodynamic properties along selected isotherms were determined. The model accurately reproduces the structure of the parent Lennard-Jones fluid and can be considered a suitable reference model for a wide range of thermodynamic conditions.

Summary: This study investigates the effect of long-range interactions on the abundance of striped metastable states in two-dimensional Ising ferromagnets. Monte Carlo simulations reveal that long-range interactions suppress the occurrence of striped metastable states at zero temperature, while at non-zero temperature the final state is always ordered.

Summary: In this paper, a field-theoretical treatment of the 2D XY model with long-range couplings is discussed, and it is compared with results from the self-consistent harmonic approximation. The results show that both power law BKT scaling and spontaneous symmetry breaking occur for the same decay rates of long-range interactions. Meanwhile, the Villain approximation fails to reproduce the correct critical behavior in the long-range regime.

Summary: We investigate the thermal, mechanical, and chemical contact of two subsystems composed of ideal gases, which are both not in the thermodynamic limit. The behavior of these small systems, determined through their connection to the phase space density (PSD), does not conform to macroscopic thermodynamics. Instead, it is the entropy defined from its connection to the PSD that still controls the behavior of these small (nonextensive) systems. We also propose an alternative entropy definition based on the phase space volume (PSV), but it does not consistently describe the behavior of small isolated systems when in contact.

Summary: We study short-range Ising spin glasses in equilibrium at infinite system size, and demonstrate that, for a fixed bond realization and a Gibbs state drawn from a suitable metastate, all translation and locally invariant functions of a single pure state in the decomposition of the Gibbs state have the same value for all the pure states in that Gibbs state. We discuss various significant applications to spin glasses.

Summary: Textured PIN-PSN-PT ceramics fabricated using a templated grain-growth approach exhibit high k(33) values of 85 to 89% and greatly increased T-rt values of 160 to 200 degrees Celsius, making them a promising alternative to single crystals for the development of advanced piezoelectric devices.

Summary: This passage addresses the seemingly contradictory state of research on short-range order in many-component alloys by critically reviewing the characterization of face-centered-cubic 3d systems. Despite the lack of direct observations, the ordering of widely studied alloys is argued to be primarily interesting for its potential ubiquity. To clarify this situation, the article proposes future research directions based on historical results, including a review of the fundamental principles of ordering and clustering.

Summary: The effects of elemental concentration, short-range ordering, and atomic segregation on the melting temperature of high-entropy alloys (HEAs) were studied. It was found that the melting temperature of HEAs increases with decreasing Cu concentration, and Cu atoms tend to break bonds more readily during heating. The reduced melting temperature is attributed to the formation of more short-range ordering and atomic segregation with increasing Cu concentration.

Summary: We investigate the quantum-critical behavior in quantum spin ladders and determine the critical phase transition line and critical exponents. The results show the absence of deconfined criticality, contrary to a recent suggestion in the literature.

Summary: The study examines the topological phase transitions in magnonic systems in honeycomb ferromagnets, where the magnon-magnon interactions cause the magnonic energy gap to close and reopen at a critical temperature. The Chern numbers of the magnonic bands are distinct above and below the critical temperature, serving as a signature for the topological phase transitions. Additionally, the thermal Hall conductivity in the magnonic system exhibits a sign reversal at the critical temperature, which can be experimentally observed and validated in materials like CrI3.

Summary: Complex concentrated alloys (CCAs) have attracted significant attention for their wide range of applications and novel properties. Chemical short-range ordering (CSRO) in CCAs plays a crucial role in understanding their properties and phase stability. This article reviews recent experimental efforts in identifying and characterizing CSRO in CCAs, and discusses theoretical and computational techniques, such as density functional theory (DFT) and molecular dynamics (MD), used to investigate CSRO effects.

Summary: This paper investigates the dynamical detection of quantum phases and phase transitions in quenched systems, revealing significant differences in scaling law exponent near the dynamical crossover between short and long times. It also shows that when integrability is strongly broken, the crossover boundary transforms into a region separating two other dynamical regions acting as dynamically ordered and disordered regimes.

Summary: The article discusses the effect of long-range decaying couplings on the BKT transition, revealing a phase diagram far richer than the short-range scenario, with a quasiordered phase existing between a symmetry broken phase and a disordered phase.

Summary: This study used NMR relaxometry to observe dynamic clusters with short-range orientational order in liquids. These clusters exhibit local order driven by interactions between molecules. In liquid crystal, the size of these clusters was observed to increase during the phase transition.

Summary: This study introduces a coherent quantum feedback control protocol that can steer a quantum system from any initial state to a target state through a series of interactions with controlling quantum systems, stabilizing and protecting against noise. The key to combating noise is weak system-controller interactions occurring at suitably high frequency. This approach provides a mechanism for autonomous, purely quantum closed-loop control.
