This paper introduces a generalized definition of dynamical activity valid at arbitrary system-reservoir coupling to derive a novel Quantum Kinetic Uncertainty Relation (QKUR) that accounts for quantum coherence and corrects the breakdown of standard relations in the strong-coupling regime of mesoscopic conductors.
This paper demonstrates that forming 2D material heterostructures on hybrid photonic crystal nanocavities enables flexible, post-fabrication dielectric environment engineering, resulting in robust high- cavities with enhanced light-matter interactions and tunable optical properties through controlled flake stacking and encapsulation.
This paper establishes a general framework for manipulating and amplifying collective bosonic modes in correlated quantum matter via parametric driving, demonstrating how this process reveals quantum geometric properties like fidelity susceptibility and enables the creation of novel non-equilibrium prethermal states.
This paper demonstrates that a universal contribution to the Casimir interaction in salted water extends its range beyond previous expectations, dominating at distances relevant to actin fibers and suggesting significant implications for biological processes at the cellular scale.
Using a scanning superconducting magnetic sensor to image local current flow in dual-gated bilayer graphene, researchers identified distinct ballistic, hydrodynamic, and diffusive transport regimes, demonstrating that the flat band regime with its large effective mass enables ultra-short electron-electron scattering lengths (~50 nm) and strong nonlinearities, thereby paving the way for miniaturized electronic devices based on electron hydrodynamics.
This paper demonstrates that a non-equilibrium open system with weak time-reversal symmetry can exhibit non-quantized Hall conductance without an external magnetic field, as interactions with bosonic degrees of freedom and an external reservoir induce a time-reversal-breaking self-energy in the fermionic subsystem, a phenomenon that requires wave-function renormalization effects beyond a simple mass term.
Using a Wannier function approach combined with density functional theory, this study calculates the optical properties and Chern numbers of MnBiTe thin films, revealing that eleven septuple-layer films share the same Chern number as five-layer films and challenging previous reports of a higher Chern-number phase.
This paper demonstrates that circularly polarized light can induce high-Chern-number quantum anomalous Hall effects and controllable orbital Hall transport in two-dimensional collinear altermagnets like VSiN through Floquet engineering of -wave odd-parity magnetism.
Using the exact hierarchical equations of motion formalism, this study reveals that increasing Coulomb interaction in triangular triple quantum dot systems uniquely enhances stationary current through the interplay of interaction-induced energy shifts and quantum interference, contrasting with the current suppression typically seen in linear arrays.
This paper theoretically demonstrates that nonlinear spin-motive force driven by magnetization dynamics generates both DC and second-harmonic AC currents originating from the quantum geometry in the mixed momentum-magnetization space, enabling AC-to-DC conversion even in insulating materials.
