We quantitatively elucidated for the first time the electronic polarization structure in epitaxial YbFe₂O₄ thin films by measuring the angle dependence of second-order nonlinear optical signals.

Phonon-induced current noise in carbon nanotubes shows multiple resonance peaks in the high-frequency regime, some of which cannot be explained solely by energy and momentum conservation or by harmonic selection rules. These findings highlight nontrivial electron–anharmonic phonon interactions governing quantum transport in carbon nanotubes.

Jewel beetles enhance their dazzling iridescence by appropriately adjusting the thickness of the surface layers in their natural multilayer reflectors, thereby achieving constructive optical interference.

This special topics edition of the Progress of Theoretical and Experimental Physics covers a symposium celebrating the 50-year history of the Kobayashi–Maskawa Theory, highlighting its impact from theoretical and experimental perspectives.

This work provides a theoretical demonstration of piezomagnetic effects in an organic altermagnet, arising from strain-induced asymmetries in exchange interactions and orbital degrees of freedom, thereby revealing new opportunities for organic spintronics.

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.
