This study explores the thermodynamic properties of finite-temperature large-N gauge theories, revealing two significant discoveries that could be instrumental for understanding the strong nuclear force and quantum gravity.

This Special Topics edition of JPSJ details the capabilities and upgrades made to the instruments at JRR-3, since its shutdown after the Great East Japan Earthquake and 2011.

Theoretical physicists propose an alternative way of performing perturbative calculations in an open string field theory that has no analogy in the standard quantum field theory formalism.

Researchers from Japan have found a novel non-equilibrium quantum system that doesn’t have the sign problem. The transport properties of the system are simulated with a Monte Carlo approach.

Scientists investigate quantum anomalies in a system of Dirac fermions with spacetime dependent mass and show that the anomaly formulas can be expressed in terms of superconnections.

Scientists measure the lifetime of a neutron with pulsed neutron beams to explore the cause of a puzzling discrepancy in their previously measured lifetime.

A set of field configurations (replicas) reaches equilibrium of quantum field theory after real-time evolution obeying classical equations of motion.

Scientists embark on a quest to unravel the mysteries behind matter–antimatter asymmetry in our universe with the new Belle-II experiment at the SuperKEKB accelerator in Japan.

Scientists for the first time theoretically link quantum states and gravity, taking one step further in understanding the origins of gravity and opening doors to novel quantum applications.

The Belle-II experiment is designed to explore new mechanisms of matter-antimatter asymmetry that may resolve the mystery behind the dominance of matter over anti-matter in the universe.
