This study reveals the early-stage dynamics of ultrasonic cavitation using a record 100-billion-atom simulation to capture bubble nucleation, growth, clustering, and periodic splitting under nonequilibrium conditions.

This review in Progress of Theoretical and Experimental Physics introduces monitored quantum systems and quantum trajectories, emphasizing their spectral properties, typical behaviors such as ergodicity and purification, and measurement-induced phases.

A minimal lattice model revealed that topological defects with winding number +1 serve as nucleation sites for phase separation in active matter systems.

This review from the Journal of the Physical Society of Japan examines how artificial intelligence overcomes traditional materials science bottlenecks, highlighting the shift from intuition-based discovery to data-driven innovation.

TbNiC₂ exhibits negative magnetization. A new mechanism, based on the coupling between the charge density wave and the antiferromagnetic order, is proposed to account for this peculiar phenomenon.

Although the Einstein–de Haas (EdH) effect describes material rotation in a magnetic field, a thermal EdH effect, driven by a temperature gradient, remains unobserved. Recently, chiral carbon nanotubes were theoretically proposed as promising candidates to observe it.

This study presents a novel route for experimentally realizing the Sachdev–Ye–Kitaev (SYK) model, considered holographically dual to charged black holes, offering the first step towards experimental studies of quantum gravity.

Electrically driven liquid-crystal turbulence generates self-sustained flow and negative apparent viscosity. The fluorinated, chemically robust nematic PPDFB shows a substantially larger negative-viscosity effect than Schiff-base nematics.

Magnetic neutron scattering holography (MNH) were performed on a Fe_0.08Co_0.92 single crystal. The resulting holograms provided the first experimental evidence that MNH is sensitive to magnetic signals.

This study investigates high-rank multipole physics in f-electron systems, providing the first clear experimental evidence for field-induced switching of ferro-quadrupole order in a non-Kramer ion system, along with a new conceptual framework
