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 demonstrates that hybrid systems combining -wave unconventional magnets and -wave superconductors induce an -wave-like superconducting state characterized by zero-energy flat bands, odd-frequency pairing, and tunable Josephson currents driven by the interplay between noncollinear magnetic order and singlet pairing.
This paper proposes and experimentally demonstrates a non-Abelian Hatano-Nelson model in electric circuits featuring a nonreciprocal U(2) gauge field, which induces unique Hopf-link-shaped energy braiding and a bipolar skin effect, thereby expanding the scope of experimental non-Hermitian physics.
This paper proposes a new topological condition requiring linearly dependent loop states to resolve singularities in flat bands, thereby enabling the realization of "topological-topological" (top) flat bands with well-defined topological invariants that can evolve into correlated topological insulators under interactions.
This paper introduces a geometric quantization framework to demonstrate that Laughlin quasiholes in the fractional quantum Hall state can form bound states driven by Berry phase effects rather than electrostatic attraction, revealing a sequence of anyon clustering phases as screening increases.
This paper identifies and characterizes two distinct topologically non-trivial gapless phases—the topological Luther-Emery liquid and the topological Mott insulator—at the boundaries of interacting spinful wires, demonstrating that despite lacking a mean-field description or local order parameter, these states can be adiabatically connected to a non-interacting topological metal with winding number .
This paper demonstrates a hybrid skin-topological effect in a non-Hermitian brick-wall lattice where the interplay of first-order band topology and non-reciprocal hopping leads to unconventional corner skin modes with dynamically stable exceptional point-like features and a distinct spatial distribution, which are experimentally visualized using a designed topolectrical circuit.
This paper theoretically demonstrates that graphene Corbino disks with a sufficient radius ratio exhibit a tunable crossover from standard Josephson tunneling to graphene-specific multimode Dirac-Josephson tunneling and finally to the ballistic Josephson effect, depending on the electrochemical potential and the spatial profile of the electrostatic barrier.
This paper investigates a hybrid triple quantum dot system to demonstrate how finite bias and detuning induce a crossover between Fano-Andreev bound states in the continuum (BICs) and quasi-BICs, characterized by sharp transport zeros and distinct occupation changes in the side quantum dots.
This paper demonstrates that incorporating trigonal warping effects into AB-stacked bilayer graphene enables a low-field metal-insulator transition at approximately 10 T, a significant reduction from previously predicted requirements, by utilizing a transverse electric field to open a gap that is subsequently closed by a relatively small in-plane magnetic field.
This paper proposes and experimentally demonstrates a robust topological plasmonic nanocavity strategy that leverages symmetry breaking to convert bound states in the continuum into a multi-BIC regime, enabling deterministic, uniform, and highly directional upconversion emission from single-particle emitters while suppressing mode perturbations.
