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 demonstrates that the local density of states induced by non-magnetic impurities in gapped two-band models can serve as a direct spectroscopic probe to extract both the wavefunction winding number and the local Berry curvature, establishing a general connection between these non-local topological properties and observable energy dispersion parameters.
Using qPlus atomic force microscopy and scanning tunneling microscopy on single-crystal Pb(111), this study experimentally demonstrates that electrostatic screening in a type-I superconductor remains governed by the Thomas-Fermi length rather than the London penetration depth, thereby contradicting J. E. Hirsch's alternative theory and confirming that the longitudinal response is unchanged upon entering the superconducting state.
This paper demonstrates that the non-adiabatic spin-transfer torque (-term) in current-driven domain walls cannot be modeled by passive circuit elements alone without violating thermodynamic principles, implying that experimental interpretations relying solely on this term are incomplete and must account for additional physical effects beyond spin dynamics.
This paper proposes an epsilon-near-zero artificial cavity to enhance light-matter coupling and theoretically demonstrates the feasibility of exciton-polariton condensation within this platform by calculating pump thresholds via a driven-dissipative rate equation model and comparing its performance to traditional distributed Bragg reflector cavities.
This paper demonstrates that Chern insulators under open boundary conditions exhibit a robust, topologically protected giant orbital diamagnetism that scales linearly with system size, a phenomenon driven by chiral edge states and fundamentally linked to the divergent diamagnetism observed in massless Dirac systems like graphene.
This paper theoretically demonstrates that the anyon-Hubbard model hosts exact few-body bound states in the continuum for arbitrary statistical phases, which are stabilized by a unique kinematic mechanism rather than conventional interactions and exhibit fast chiral transport properties that can be experimentally probed via expansion dynamics.
This paper attributes the absence of superconductivity in bulk doped infinite-layer nickelates to the formation of nickel clusters and nickel-deficient regions, a conclusion supported by both a simple magnetostatic model and Density Functional Theory calculations.
This review provides a comprehensive overview of levitated optomechanics with a specific focus on the classical and quantum aspects of roto-translational motion in optically levitated anisotropic objects, detailing the underlying mechanisms, experimental approaches, and future applications such as quantum-limited torque sensing and the creation of non-classical states.
This paper rigorously derives formulas for the orbital magnetization and magnetic susceptibility of interacting electrons within the Hartree-Fock approximation, revealing that while magnetization follows the non-interacting form with Hartree-Fock replacements, susceptibility requires an additional interaction-induced term, a finding validated through tests on an interacting Rashba model.
This paper demonstrates that tunneling Andreev reflection (TAR) spectroscopy, by leveraging the additivity of excess decay rates to disentangle Andreev and quasiparticle currents, provides a robust, atomically resolved method for identifying superconducting pairing symmetries that overcomes the limitations of traditional conductance-based techniques.
