Explore the fascinating intersection where quantum materials meet the complexity of everyday environments in the Cond-Mat — Mes-Hall section. This field investigates how tiny particles behave when caught between the orderly world of single atoms and the chaotic nature of bulk matter, revealing the hidden rules that govern electricity, magnetism, and heat in novel substances.

This paper proposes a method using the static structure factor to systematically arrange isotopic defects in a harmonic chain, thereby enabling tunable, frequency-selective control over phonon transmission to achieve either transparency or opacity.
Using a Ginzburg-Landau framework, this study demonstrates that magnetic skyrmions and superconducting vortices in ferromagnetic superconductors form stable bound states exhibiting short-range repulsion and long-range attraction, which drives clustering and offers a theoretical basis for controlling hybrid topological matter.
This paper demonstrates that optimizing the defect density and interfaces of piezoelectric films in high-overtone bulk acoustic-wave resonators enables phonon lifetimes up to 400 μs and a record-high quantum coherence cooperativity of when coupled to superconducting qubits, establishing a new milestone for circuit quantum acoustodynamics devices.
This paper develops a gauge-invariant geometric perturbation theory for Bloch states that constructs a hierarchy of dressed dispersion and connection terms to describe nonlinear transport, specifically deriving the fully coherent, purely geometric third-order response to a uniform electric field.
This paper demonstrates that while spin-independent dissipation eliminates second-order exceptional points in finite-gap superconducting double-quantum-dot Josephson junctions, the combination of spin-dependent dissipation from a ferromagnetic reservoir and magnetic flux tuning not only stabilizes these singularities but also enables the formation of third-order exceptional points with cubic-root scaling, all while maintaining continuous Josephson currents across the non-Hermitian singularities.
This paper establishes a unified geometric framework for weak topological phases by demonstrating that edge states, corner modes, and compact localized states correspond to exceptional points and curves within the complex-momentum space of an analytically continued Bloch Hamiltonian.
Using scanning tunneling microscopy/spectroscopy combined with ab initio simulations, this study identifies a b-axis-aligned double sulfur vacancy as a common intrinsic defect in CrSBr and characterizes its structural and electronic signatures near the valence band edge.
This study demonstrates that in superconducting NbSe2, Meissner currents induced by an in-plane magnetic field selectively Doppler-shift Bogoliubov quasiparticle spectra at charge density wave vectors, thereby driving a symmetry-breaking transition in CDW modulations and enabling momentum-space engineering of intertwined electronic phases.
This paper employs a microscopic theory of nonlocal susceptibility to demonstrate that the spatial dispersion of Landau levels in GaAs quantum wells significantly modifies Purcell factors, Lamb shifts, and emission spectra up to hundreds of nanometers, notably enhancing dipole-forbidden transitions through near-field gradients.
This paper demonstrates an all-van der Waals high- nanobeam laser based on a WS/MoSe/WS heterostructure that achieves lasing with near-unity and direct quantum-optical verification of the transition from thermal to Poissonian photon statistics, establishing a scalable platform for integrated coherent light sources.
