This paper develops a theory of dynamical superradiance in organic materials by modeling vibrational effects through both Markovian dephasing and the Holstein–Tavis–Cummings Hamiltonian, revealing that vibrational coupling can enhance superradiance under negative cavity detuning and identifying an asymmetry in photon rise time as an experimental signature.
This paper presents a rigorous quantum theory of the exciton orbital magnetic moment that incorporates electron-hole interactions and quantum geometric effects, revealing three distinct contributions that resolve long-standing discrepancies between theoretical predictions and experimental observations in materials like biased bilayer graphene.
This perspective paper advocates for the use of process tensor approaches combined with efficient tensor-network methods to overcome the limitations of traditional Markovian approximations, enabling the practical and accurate description of complex non-Markovian dynamics in diverse open quantum systems.
This paper theoretically demonstrates that while edge currents in two-dimensional topological superconductors vanish for non-chiral states, edge noise remains non-zero and serves as a topological indicator linked to the Chern number or other invariants like the Zak phase, with bulk noise acting as a topological susceptibility that peaks during phase transitions.
Using scanning tunneling microscopy, researchers visualize interaction-driven symmetry-breaking Chern insulators in bilayer graphene aligned with hexagonal BN and observe their quantum melting and phase transitions within the Hofstadter spectrum.
This paper theoretically analyzes the cyclotron resonance absorption in graphene-TMD heterobilayers, revealing that proximity-induced spin-orbit coupling creates a fine double-peak structure in interband transitions and enables new spin-flip combined cyclotron resonance modes with distinct selection rules and polarization dependencies.
This paper proposes a scheme for realizing locally gate-controlled spin qubits in electrostatically confined altermagnetic quantum dots that operate without spin-orbit coupling, utilizing anisotropic confinement and resonant modulation to achieve single-qubit rotations and generate maximally entangled two-qubit states.
This paper reports the first experimental demonstration of electrical readout for 180-degree Néel vector reversal in atomically thin van der Waals antiferromagnetic CrSBr films by utilizing spin-dependent tunneling magnetoresistance in a heterostructure coupled to a spin-polarized layer.
This paper proposes and demonstrates a novel information processing scheme that leverages the dynamical properties of memristors rather than their multi-level resistance states, enabling complex tasks such as autonomous neural spike detection and high-accuracy time-series prediction using circuits composed of only two memristors.
This paper theoretically investigates Wigner crystallization in Bernal bilayer graphene under perpendicular displacement fields, revealing that Berry curvature induces spontaneous orbital magnetization and trigonal warping causes a "doubly re-entrant" phase behavior with nontrivial minivalley order, while also mapping the state's phase boundaries in terms of density, field, and temperature.
