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

This study introduces a refined framework for primordial black hole formation, replacing older approximations with peak theory and physical collapse criterion, resulting in revised predictions for their mass and abundance.

We derive a generalized modular bootstrap equation for conformal field theories on unorientable manifolds in the presence of symmetry defects and identify new crosscap states labeled by noninvertible symmetries.

In many energy devices, electron transfer occurs between ions dissolved in the electrolyte and the electrodes. For keep current flowing, new ions must be supplied continuously to the electrode surface from the bulk region. The diffusion layer’s role in diffusive mass transfer was clarified using the rotating disk electrode method.

We present a Bayesian framework for angle-resolved hard X-ray photoelectron spectroscopy (AR-HAXPES), combining Replica Exchange Monte Carlo with hierarchical integration to objectively and precisely estimate thin-film thickness.

A theoretical framework was developed to describe nonequilibrium electron distributions across the ballistic, diffusive, and local equilibrium transport regimes in voltage-biased nanowires in a unified manner.

Using high-quality UTe₂ (T_c = 2.1 K), we identify its nodal gap structure. Field-angle‑resolved specific‑heat reveals a b-axis singularity, supporting spin-triplet superconductivity with nodes along the b axis.

An effective model based on magnetic anisotropy arising from a crystalline electric field is constructed for icosahedral approximants, which not only explains measured ferromagnets and antiferromagnets but also reveals new types of noncollinear magnetic orders.

Researchers at the Institute for Molecular Science (IMS) have utilized a cutting-edge Photoelectron Momentum Microscope (PMM) at the UVSOR Synchrotron Facility to settle a two-decade-long controversy concerning the direction of electron spin on the Au(111) surface. This study provides a definitive, full-map, comprehensive reference for quantum imaging that is essential for advancing spintronics technology.
