A novel convolutional neural network predicts phase transition temperatures from spin configurations without prior information about order parameters, paving the way for the discovery of new materials in condensed matter physics.

The replica method maps matrix-valued geometric Brownian motion to a mean-field quantum spin system. This correspondence makes it possible to obtain an exact solution for matrix-valued geometric Brownian motion.

Focusing on a CMOS NAND GATE operating in a sub-threshold region, the thermodynamic cost of computation was analyzed in relation to input/output voltages surpassing the Landauer limit.

This Special Topics Edition of the JPSJ describes the latest advances in the field of biofluid locomotion, shedding light on the underlying physics behind the movement of organisms that swim and fly.

A groundbreaking study reveals a new time-local fluctuation theorem using machine learning, revolutionizing our understanding of deterministic nonequilibrium steady state systems.

The surface of muskmelon is covered with a fine mesh-like net-pattern. The geometric features of the fine mesh appear unique for each individual, but hide an unexpected mathematical rule.

Researchers from Japan provide the first comprehensive review of the historical development of tensor networks from a statistical mechanics viewpoint, with a focus on its theoretical background.

We study equilibrium current fluctuations in systems without time-reversal symmetry, violating the fluctuation-dissipation theorem. Notably, the off-diagonal fluctuation is insensitive to system imperfections in contrast to other fluctuations and conductivity.

It is preferable to avoid lockdowns, as lockdowns at seriously spread phases are very expensive. It would be economically better to utilize less intense countermeasures as early as possible to avoid lockdowns in later phases.

For the first time, the main assumption of the transition-state theory for the decay of complex quantum systems across a potential barrier was realized using a microscopic many-body Hamiltonian.

We theoretically showed that electric quadrupoles in some heavy fermion materials exhibit a very rich phase diagram including unique partially-ordered phases stabilized by an interaction specific to these systems.

Theoretical investigations have unearthed a plethora of electronic nematic orderings driven by the spatial distribution of atomic-scale electric quadrupoles.

We numerically diagonalize the Dimer-Trimer (DT) model Hamiltonian around the SU(3) symmetric point. As a result, we discover the phase transition at this point which belongs to the Berezinskii-Kosterlitz-Thouless (BKT)-like universality class.

We theoretically showed an intrinsic splitting instability of composite domain walls in multiferroic materials under field drive. This instability is a direct result of the coexistence of multiple orders in the system.

Group testing is a method of identifying infected patients by performing tests on a pool of specimens. Bayesian inference and a corresponding belief propagation (BP) algorithm are introduced to identify the infected patients in group testing.

A researcher has developed a new theory to describe the Brownian motion of a small object that is confined in a fluctuating random surface.

Localization may cause the inefficiency of quantum annealing. The constrained quantum annealing of graph coloring provides a new viewpoint to analyze localization phenomena in quantum annealing.

In quantum liquids, large differences are observed owing to differences in quantum statistics. The physical properties of liquid ³He (Fermion) and ⁴He (Boson) are considerably different at low temperatures. After the discovery of superconductivity in electron (i.e., Fermion) systems, a similar pairing ordered state was expected for ³He. Remarkably, the observed ordered state of ³He was more surprising than expected, multiple superfluid phases in the T–P phase diagram. The origin of the multiple phases was attributed to ferromagnetic interactions in the p-wave symmetry state.

The nonlinear conduction (the deviation from Ohm's law) has been discovered universally in various correlated materials. This may be explained by the percolation conduction in disordered materials.
