This paper argues that the persistent failure of independent electron models to explain the chirality-induced spin selectivity effect necessitates a theoretical framework incorporating electron correlations, which may lead to the spontaneous breaking of time-reversal symmetry and Onsager reciprocity.
This paper introduces an exactly solvable dissipative Yao-Lee spin-orbital model that maps to a non-Hermitian fermionic system, revealing an exponentially large manifold of non-equilibrium steady states and a symmetry breaking transition characterized by an exceptional ring in the Liouvillian spectrum.
This study resolves the apparent discrepancy between superconducting phase diagrams in twisted bilayer WSe at different twist angles by demonstrating a smooth evolution of superconductivity across the range, revealing its consistent proximity to Fermi surface reconstruction and antiferromagnetic ordering rather than specific singularities, thereby establishing the system as a versatile platform for investigating correlated phases.
This paper theoretically demonstrates the effective readout of a two-qubit silicon spin qubit system using gate-all-around transistor simulations and SPICE circuit analysis, confirming that a conventional CMOS sense amplifier can detect state-dependent current variations through dynamic voltage control.
This paper proposes decorated Landau levels (dLLs), formed by imposing an electrostatic delta potential lattice within a single Landau level, as a tunable theoretical framework and experimental platform for realizing robust, exotic interacting topological phases where Hall conductivity deviates from the filling factor due to complex Berry curvature distributions and suppressed band mixing.
This paper introduces an atom-by-atom inverse design framework that integrates Nano-Topology Optimization with conditional diffusion models to overcome continuum limitations by explicitly accounting for crystal symmetry and surface physics, thereby enabling the discovery of high-performance metallic nanostructures like aluminum nanocantilevers and nanopillars.
This paper proposes a method for rapidly entangling spin qubits, specifically resonant exchange qubits, using capacitive coupling mediated by an ac-driven multielectron quantum dot to achieve single-pulse universal gates without leakage mitigation, thereby enabling modular spin-based quantum information processing when integrated with long-range cavity-mediated approaches.
This paper establishes a universal scaling rule linking molecular anharmonicity, excitonic coupling, and Rabi splitting to demonstrate how intrinsic many-body interactions can resurrect genuine polaritonic double-quantum coherences in molecular ensembles, which are otherwise suppressed by collective cavity delocalization, thereby providing a predictive framework for engineering robust optical nonlinearities in J-aggregates.
This paper demonstrates coherent, broadband microwave-to-optical transduction in the layered antiferromagnet CrSBr by leveraging strong magnon-exciton coupling at excitonic resonances, offering a scalable and efficient alternative to existing transducer technologies that often sacrifice performance for noise reduction or integrability.
This paper details the design, fabrication, and validation of a Quantum Twisting Microscope built on a commercial atomic force microscope, demonstrating its capability to perform twist-angle-dependent electronic measurements on layered materials with observed conductance periodicity consistent with hexagonal lattice symmetry.
