Lieb-Schultz-Mattis-Type and Laughlin-Type Argument for the Quantum Hall Effect in Lattice Fermions with Spiral Boundary Conditions

This paper derives the condition for the integer quantum Hall effect in interacting two-dimensional lattice systems by employing spiral boundary conditions to treat the system as an extended one-dimensional chain, thereby obtaining the relationship between magnetic flux, Chern number, and electron density directly through a combined Lieb-Schultz-Mattis and Laughlin-type argument without the redundant system-size dependence found in conventional periodic boundary approaches.

In-Substrate Imaging of Diamond hBN FET Current via Widefield Quantum Diamond Microscopy

This study demonstrates widefield quantum diamond microscopy using in-substrate nitrogen vacancy centers to noninvasively image and correlate micrometer-scale current distributions with electrical characteristics in hydrogen-terminated diamond field-effect transistors, revealing insights into channel transport, dielectric non-uniformities, and photo-induced electrostatic effects.

Anomalous valley Hall dynamics of exciton-polaritons

This paper reports the observation of an anomalous optical valley Hall effect in monolayer WS2 exciton-polaritons, where a strain-induced synthetic pseudomagnetic field drives ultrafast spatial separation of valley-polarized states, establishing a high-speed platform for valleytronic and topological photonic applications.

Buried Dirac points in quantum spin Hall insulators: Implications for Majorana Kramers pair-based quantum computing

This study demonstrates that InAs/GaSb quantum spin Hall insulator-superconductor junctions exhibit robust edge state transport up to 2 T due to buried Dirac points, a feature that theoretically supports the formation of extended Majorana Kramers pairs essential for fault-tolerant quantum computing.

Enhanced chemical vapour deposition of monolayer MoS2 films via a clean promoter

This paper presents a novel contamination-free chemical vapour deposition method using a clean promoter to achieve the scalable synthesis of high-quality, large-area monolayer MoS2 films with superior optical properties, thereby overcoming key barriers for their integration into next-generation electronic devices.

Defect-modified acoustic phonons in a single layer of MoS2

Using helium-3 spin-echo spectroscopy, this study reveals that atomic-scale defects in monolayer MoS2 fundamentally alter acoustic phonon dispersions by inducing a transition from continuum elastic behavior to defect-pinned standing waves, thereby explaining the material's anomalously low thermal conductivity through suppressed group velocities and enhanced four-phonon scattering.

Ultrafast interband transitions in nanoporous gold metamaterial

This study reveals that nanoporous gold metamaterials exhibit enhanced ultrafast interband transitions at lower energies compared to continuous gold films due to higher electron temperatures and efficient hot carrier generation enabled by nanoscale porosity, establishing them as tunable temporal metamaterials with broad implications for photochemistry, catalysis, and optoelectronics.

Interplay of spin orbit interaction and Andreev reflection in proximized quantum dots

This paper investigates a hybrid device of two quantum dots coupled to a superconductor and a spin-orbit semiconductor, demonstrating that a specific balance between spin-orbit interaction and crossed Andreev reflection creates a "sweet spot" where fully spin-polarized, zero-energy Majorana-like quasiparticles emerge, enabling perfectly entangled electron transport.
