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.

Below are the most recent papers in this dynamic area of condensed matter physics, ready for you to explore.
This paper introduces the "Bott metric," a real-space measure derived from plaquette operators that captures amplitude information complementary to the topological Bott index, thereby unifying topological invariants and the quantum metric to characterize non-periodic quantum systems.
This paper demonstrates that dissipation-induced interband processes generate a nonreciprocal current in time-reversal symmetric, noncentrosymmetric crystals, a phenomenon inversely proportional to the lifetime and governed by the shift vector, particularly in minigap systems like the Rice-Mele model.
This study demonstrates that carrier multiplication in core/shell FAPbI3/NdF3 perovskite nanocrystals reduces the optical gain threshold by half, offering a promising pathway toward achieving continuous-wave lasing with lower optical-pumping requirements.
This study employs a variational Gutzwiller wavefunction approach on an 8-band model to reveal that magic-angle twisted bilayer graphene exhibits a dome-shaped Fermi liquid phase separating weakly and strongly correlated superconducting regimes, with the latter characterized by a nematic, nodal-gap state stabilized by interaction-driven gap reconstruction and distinct from conventional Mott insulators.
This paper proposes a globally-admissible phenomenological spectral density model for the non-Markovian Brownian motion of an optomechanical resonator that resolves divergence issues while reproducing observed non-Ohmic behavior, thereby enabling the reconstruction of the full mechanical susceptibility and providing a consistent framework for probing structured environments in cavity optomechanics.
This paper employs mean-field theory, Mayer's f-functions, and Hill's nanothermodynamics to model phase transitions in MOF-confined fluids, revealing that pore size dictates whether the transition is discontinuous or continuous while demonstrating that confinement lowers the free-energy barrier and condensation pressure compared to bulk fluids.
By applying an unrestricted real-space Hartree-Fock method to the Kane-Mele-Hubbard model, this study reveals that electron doping in TMD moiré superlattices induces quantum anomalous Hall crystals characterized by tunable skyrmion lattices and topological domain walls hosting chiral modes, which persist even when the intrinsic topological gap vanishes.
This study employs the transfer matrix method to analyze relativistic particles in super-periodic potentials, revealing enhanced Klein tunneling and resonance-dependent transmission in graphene monolayers while characterizing unique tunneling behaviors in General Cantor and General Smith-Volterra-Cantor fractal systems.
This paper identifies a non-equilibrium state induced by current bias in a Rashba system as the microscopic origin of the Josephson diode effect, demonstrating that an in-plane magnetic field perpendicular to the current creates an asymmetric Josephson coupling whose magnitude and sign can be optimized by tuning the electrode distance.
This paper investigates tungsten silicide fluxonium qubits and resonators fabricated from quasi-two-dimensional amorphous films, revealing that energy loss is primarily driven by localized quasiparticles trapped in spatial variations of the superconducting gap, with loss increasing alongside the level of disorder.
