Nanodiamonds containing nitrogen-vacancy centers can be used to map pressure and nonhydrostatic stress inside diamond anvil cells to obtain micron-scale pressure landscapes that clarify local conditions affecting high-pressure materials research.

This Special Topics edition of the Journal of the Physical Society of Japan discusses the recent progress and future directions for the rapidly progressing field of photodriven quantum spin systems.

The proposed hybrid quantum-classical computing method enables practical calculations of quasiparticle band structures to expand the possibilities for quantum materials research.

The special topics edition of the Journal of the Physical Society of Japan presents five new review articles offering cutting-edge information on the emerging field of topological photonics.

We demonstrate a new type of magnetoelectric effect in the pyroelectric ferrimagnet CaBaCo₄O₇—modulating its phase stability depending on the relative direction between the electric field and its electric polarization, enabling new material design strategies.

This work provides the first observation of the superconducting gap in molecular superconductors and their gap symmetry using photoemission spectroscopy, which will significantly accelerate the study of molecular conductors.

Encoding fracture physics in neural networks provides fast and accurate estimates of the distribution of fragment sizes in shrinkage-induced cracking and facilitates Bayesian analysis for a deeper physical understanding of fractures.

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.
