Microscopic Evidence for a Zhang-Rice Triplet State in the van der Waals Antiferromagnet, NiPS3 (pub... Jul 20, 2026 l Hit 39

NiPS3 is one of representative van der Waals antiferromagnets which exhibit unusual light-matter interaction coupled with the magnetic order. It exhibits a highly coherent many-body exciton peak (< 0.5 meV linewidth) around 1.478 eV under a low-temperature zigzag magnetic order, which vanishes when the magnetic...

Chirality, a central concept across many scientific disciplines, continues to inspire the discovery of novel physical phenomena. In condensed matter physics, structural chirality—defined by the absence of mirror plane symmetries—has primarily been explored in bulk materials. However, new chiral ph...

Dysregulation of Polycomb Repressive Complex 2 (PRC2) contributes to cancer. Of its catalytic subunits, Enhancer of Zeste (EZH) 1 and EZH2, EZH2 mutations are extensively studied, but the role of EZH1 in cancer remains largely unexplored. Here, we investigate the thyroid cancer-associated EZH1Q571R mutation and un...

In flat-band systems with quenched kinetic energy, most of the conventional length scales related to the band dispersion become ineffectual. Although a few geometric length scales, such as the quantum metric length, can still be defined, because of their embedding dependence, i.e., the dependence on the choice of orbit...

Without discrete pixels or wired leads, natural plant leaves respond to light and relay electrochemical signals to surrounding tissues through nanoscale chlorophyll-containing protein complexes - an elegant capability sought in next-generation leadless optoelectronic systems. Although semiconductors and their heterojun...

[Quantum Gas Lab] Enhancement of damping in a turbulent atomic Bose-Einstein condensate (published i... Jun 24, 2026 l Hit 102

Turbulence enhances momentum transport in classical fluids, effectively increasing their viscosity. We investigate an analogous effect in a superfluid by measuring the damping of collective oscillations in an atomic Bose-Einstein condensate (BEC) containing stationary spin-superflow turbulence. Using continuous spin dr...

Eukaryotic transcription termination remains incompletely understood. Using single-molecule fluorescence assays, we examined intrinsic termination by human RNA polymerase III (RNAP3) and identified mechanistic trifurcation leading to readthrough and two termination pathways with distinctive dissociation kinetics. The d...

Moiré superlattices in van der Waals heterostructures are powerful tuning knobs for engineering electronic band structures and emergent phases. Expanding this framework to multi-moiré architectures enables discovery of novel quantum states, as hierarchically superposed patterns generate a versatile and so...

Flat bands have been proposed in various geometrically frustrated lattices, yet their experimental realization has been limited only to the two-dimensional (2D) kagome and three-dimensional (3D) pyrochlore lattices. While synthesizing bulk crystals with desired lattice geometry is generally challenging, the surfaces of...

Silicon-quantum-dot spin qubits have become a promising platform for scalable quantum computing because of their small size and compatibility with industrial semiconductor manufacturing processes. Although Si/SiGe heterostructures are commonly used to host spin qubits due to their high mobility and low percolation dens...
