A newly discovered phase in layered organic conductors exhibits enhanced magnetic susceptibility, indicating two-dimensional charge ordering, which is distinct from both the charge-glass and three-dimensional charge-ordered phases.

This review explores recent experimental advances in the emerging field of orbitronics, focusing on orbital current mechanisms and orbitronic phenomena, providing key research directions for developing energy-efficient memory devices.

Antisite defects in Fe_₂VAl create resonance states that boost hole scattering, which shifts carrier dominance to electrons and reverses thermoelectric polarity, thereby offering a new path for material design.

Discovery of new superheavy elements require beams beyond the emblematic Calcium-48. Intense titanium-50 beams open a new route used in the present tentative synthesis of oganesson (Z=118).

This study identifies physical processes behind the simple unified formula for orbital magnetic susceptibility in solids, including contributions from four different sources, offering new insights into the understanding of the nature of Bloch electrons in magnetic field.

A novel synergy between an active matter model and a machine learning algorithm has been discovered, revealing the possibility of new phases in active matter.

Vanadium dioxide exhibits a current-induced non-equilibrium phase transition that is distinct from Joule heating, and is characterized by non-linear conduction and collective electron behavior under surprisingly small electric fields.

This study explores dimensionality reduction in fluid dynamics using “autoencoder”, a nonlinear machine learning method, to represent complex flows with fewer variables and more efficiently than with traditional linear techniques.  

This study demonstrates that the fourth moment of nuclear charge density obtained from electron scattering helps estimate neutron distributions—enabling reliable neutron-skin thickness measurement relevant to nuclear physics and astrophysics.

We theoretically demonstrate the emergence of finite-momentum superconductivity in a two-dimensional altermagnet with Rashba-type spin–orbit coupling (RSOC), where anisotropic deformations of the Fermi surfaces stabilize this unconventional superconducting state.
