[Quantum Gas Lab] Enhancement of damping in a turbulent atomic Bose-Einstein condensate (published i... Jun 24, 2026 l Hit 6

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...

Unveiling the Correlation Between Chiral Spin Texture and Electronic Nematicity in Co1/3TaS2 Co1/3TaS2 (hereafter CTS), a magnetic ion-intercalated transition metal dichalcogenide, is well known for hosting a spontaneously chiral spin texture. Due to this unique structure, it exhibits a giant Hall effect even in a...

[Prof. Je-Geun Park] Cross-probing van der Waals multiferroics (published in Nature Reviews Physics) Jun 2, 2026 l Hit 71

Multiferroic materials, with coupled electric and magnetic orders, hold the potential to enable low-power memory and logic devices by replacing electrical currents with electric fields for magnetic switching. Reducing the dimensionality of multiferroics, from 3D to 2D, has opened new frontiers in this already burgeonin...

2D van der Waals magnets: From fundamental physics to applications Scientific discovery is often described as walking into a dark room and turning on the light. The discovery of 2D magnetism in van der Waals materials in 2016 was one such leap forward, removing one spatial dimension from macroscopic materials. The stud...

Fragility of Topology under Electronic Correlations in Iron Chalcogenides The interplay between topology and electronic correlations is one of the central topics in the study of quantum materials. Topological surface states are typically described within an effective single-particle picture in which electronic quasipar...

Parton distribution functions (PDFs) are central to precision QCD phenomenology. Their Mellin moments can be computed on the lattice, but direct determinations using local operators, besides ⟨x⟩, face severe challenges from reduced hypercubic symmetry, limiting results to the lowest moments. A recently proposed me...
