Summary: Current quantum simulation experiments are exploring nonequilibrium many-body dynamics with previously inaccessible regimes, using machine learning techniques to study thermalization behavior. By employing supervised and unsupervised training methods, researchers distinguish non-equilibrium from equilibrium data and use network performance as a probe for system thermalization behavior.

Summary: The thermodynamic curvature behaves similarly in the Hawking-Page phase transition and the second-order phase transition of the AdS black hole, showing specific patterns related to the spacetime dimension. As the number of spacetime dimensions approaches infinity, the ratio of thermodynamic curvatures in the two different phase transitions tends to a natural constant, indicating a fundamental difference between the two transitions.

Summary: This study proposes the use of a correlated noise bath to drive an optically trapped Brownian particle that mimics active biological matter. By controlling different parameters with unprecedented accuracy, the researchers are able to reach strongly correlated regimes that are not easily accessible in real active matter. They found that by adjusting the correlation time of the noise as a control parameter, transitions between two nonequilibrium steady states can be triggered without expending work but with a calorific cost. The measured heat production is directly proportional to the spectral entropy of the correlated noise, similar to Landauer's principle.

Summary: This study explores the thermodynamic properties of conical or BTZ-like black holes, including the relationship between temperature and thermal stability relative to the horizon radius, and investigates the thermodynamical geometries and scalar curvatures of BTZ-like black holes. Key discussions include inversion temperatures, inversion curves, and the cooling and heating areas in thermodynamic expansion.

Summary: The study reveals the significant influence of driving direction on different activity and clogging states of run-and-tumble active matter disks driven over a periodic obstacle array. Diluting obstacles can enhance mobility under low activity conditions, but mobility is more robust against obstacle dilution under high activity conditions.

Summary: Understanding black hole microstructure through thermodynamic geometry provides deeper insight into black hole thermodynamics in modified gravities. In this study of d-dimensional charged Gauss-Bonnet anti-de Sitter black holes, it is found that small-large black hole phase transition is universal and the black hole horizon radius can serve as an order parameter. Charged black holes allow repulsive interactions and undergo changes in microscopic interactions during the small-large black hole phase transition. These findings shed light on the microstructure of charged black holes in Gauss-Bonnet gravity.

Summary: We investigate the effects of density fluctuations on the near-ordering phase of a flock by studying the Malthusian Toner-Tu theory. We show that unlike its incompressible counterpart, in the Malthusian theory density fluctuations may turn the phase from continuous to first-order.

Summary: We experimentally demonstrate that information engines in contact with an out-of-equilibrium bath can convert thermal fluctuations into work at rates much higher than the traditional engines. By adding a fluctuating electric field, the work extraction can be increased up to ten times, limited only by the strength of the applied field. This connects Maxwell's demon with energy harvesting and shows the superior performance of information engines in non-equilibrium baths.

Summary: This study explores an idealized model for ion exchange and finds that the nature of interactions between sites in compositionally impure crystals strongly impacts exchange trajectories. Elastic deformations promote spatially modulated patterns, which can be observed in core/shell nanocrystals. The core of such nanocrystals undergoes a phase transition from modulated to unstructured when the thickness or stiffness of the shell is decreased.

Summary: Boundary effect and time-reversal symmetry are investigated in an active matter system consisting of biology-inspired robot-environment interaction. The system exhibits field-driven motion and follows rules of resource search, consumption, and recovery. A series of boundary-dependent phase transitions and time-reversal symmetry-breaking evolution, termed orderly hysteresis, are observed in an environmental compression-expansion cycle. The influence of environmental recovery rate on the swarm's dynamic collective behavior is analyzed.

Summary: Spontaneous pattern formation in living systems is driven by the interplay between reaction-diffusion chemistry and active mechanics. In this study, a minimal model of coupling between reaction-diffusion and active matter is analyzed, revealing that the propagation of a front is maintained in active systems with distinct effects from different types of stress.
