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...

Single-photon emission from two-dimensional perovskites channeled through low-energy edge states Two-dimensional perovskites, an emerging family of van der Waals materials with an innate quantum-well structure, exhibit remarkable optical characteristics and compositional tunability. However, their potential as a source...

Magnetic topology is central to modern quantum magnet, where spin chirality governs exotic spin winding, real-space Berry phase, and topological Hall effect. A key unresolved challenge is how to electrically switch topological spin chirality and its associated gauge flux, an essential requirement for manipulating its t...

Tunable chiral and nematic states in the triple-Q antiferromagnet Co1/3TaS2 Complex spin configurations in magnetic materials, ranging from collinear single-Q to non-coplanar multi-Q states, exhibit rich symmetry and chiral properties. However, their detailed characterization is often hindered by the limited spa...

We report a three-terminal, ion-gel-gated, redox-active molecular transistor that exhibits synaptic plasticity and analog conductance states. The device was composed of a ferrocene-terminated alkanethiolate self-assembled monolayer as the active channel, vertically sandwiched between a monolayer graphene source and a A...
