This paper presents a universal framework and numerical optimization strategies for a measurement-based quantum thermal machine using a coupled two-level Ising system, demonstrating that such engines can achieve high efficiency and robustness against errors while being directly implementable with current quantum technologies.
This paper analyzes electric current fluctuations in a minimal Kitaev chain using the differential effective charge, revealing that specific charge values ( and ) serve as unique signatures of poor man's Majorana states and their nonequilibrium dynamics across different bias voltage regimes.
This study introduces five tight-binding models of polyacene chains to demonstrate that while $cis$- and $trans$-polyacene share identical band structures, they exhibit opposite topological characters, with $trans$-polyacene being nontrivial and $cis$-polyacene being trivial, while two of three modified polyacene structures also display exotic topological behavior.
This paper proposes that the real-space area enclosed by a localized particle's micromotion during a Floquet period serves as a local bulk indicator for anomalous topological phases, establishing a direct proportionality between this area and the system's winding number to enable detection in disordered or interacting quantum simulations.
This paper proposes that correlation-driven spontaneous orbital order provides a general mechanism for realizing two-dimensional metallic altermagnets, identifying monolayer YbMnGe as a stable material with giant nonrelativistic spin splitting and large, gate-tunable transverse spin conductivity.
This paper demonstrates how tensor network methods can efficiently solve the unfactorized Schrödinger equation for bound electron-hole complexes in CdSe nanoplatelets, bridging the gap between weak and strong confinement regimes to calculate accurate energies and oscillator strengths for various excitonic and trionic states.
This paper provides a comprehensive analysis of topological end states in honeycomb nanoribbons by demonstrating how specific terminations quantize the multiband Zak phase to govern state robustness, while also elucidating how complex next-nearest-neighbor hopping breaks chiral symmetry and depins end-state energies within the Haldane and Kane-Mele model frameworks.
This paper establishes a systematic framework linking the Hessenberg structure of symmetry-preserving perturbations to the order of Puiseux series singularities at exceptional points in non-Hermitian systems, demonstrating that while parity and charge-conjugation symmetries restrict third-order exceptional points to square-root branch points, parity-time symmetry generically allows for the strongest cubic-root singularities.
This study demonstrates that single Dysprosium atoms on NaCl(100) films, particularly those substituting surface sodium ions, exhibit thermally stable magnetic bistability up to 300 K and long spin relaxation times, establishing NaCl as a viable platform for single-atom magnets.
This paper theoretically demonstrates that the interplay of quantum confinement and proximity effects in metallic bilayer heterostructures can significantly enhance the critical temperature and induce superconductivity in materials that are non-superconducting or weakly superconducting in their bulk forms.
