Two isolated cardiomyocytes (heart muscle cells) can synchronize through deformations of a soft substrate. A dynamical theory explains geometry-dependent phase-locking and synchronization time.

Holonomy measures how local optical directions fail to return to their original orientation after a closed loop, revealing hidden electromechanical structures in stress-induced ferroelectric SrTiO₃.

Recent precise NMR measurements on the heavy-fermion superconductor UBe₁₃ provided “smoking-gun” evidence for a fully-gapped spin-triplet superconducting state, opening a new chapter in the field.

This study proposes an SIS competition model that integrates rumor spread and opinion changes. This analysis reveals novel mechanisms for conflicting rumor coexistence, thus demonstrating that rumors paradoxically survive through low transmissibility.

Using a newly developed intense ²⁰⁸Pb beam at the RIKEN RI Beam Factory (RIBF), we discovered 22 new proton- and neutron-rich isotopes, which significantly expand the nuclear chart.

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.
