This paper predicts that step edges on the surface of three-dimensional topological metals exhibit a robust, non-integer quantized conductance determined by bulk topology, extending the bulk-boundary correspondence to gapless systems and aligning with recent experimental observations of enhanced density of states at such edges.
This paper proposes a theoretical framework for neuromorphic computing using networks of blue-detuned optomechanical oscillators, demonstrating their potential for machine learning applications through the analysis of collective synchronization and the successful modeling of an XOR gate.
This paper introduces a theoretical framework for bilayer planar cavities, demonstrating that the geometric placement of two magnetic films and their symmetry properties enable precise control over collective magnon-polariton excitations by modulating coupling strength, activating dark modes, and organizing multimode interactions through exchange-driven hierarchies.
This paper employs first-principles simulations of the full unitary dynamics in circuit QED to demonstrate that the observed drop in qubit and readout fidelity at high drive amplitudes is critically sensitive to the microscopic details of the bath spectrum, revealing limitations in standard Lindblad and effective master equation approaches.
This study demonstrates that CrSBr photonic crystal slabs enable active magnetic control over self-hybridized exciton-polaritons, where a small external magnetic field of 40 mT triggers a spin-flip transition that reverses the polariton group velocity and switches its propagation direction.
This study demonstrates that while finite temperatures can completely quench particle transport over high potential barriers at intermediate ranges for both Langevin and Basset-Boussinesq-Oseen (BBO) dynamics, hydrodynamic memory in BBO systems uniquely mitigates this effect by sustaining initial momentum, thereby enabling transport even in regimes where thermal fluctuations would otherwise halt it.
This paper generalizes the dynamical Keldysh model to describe electrons in random time-dependent fields with finite correlation times and transfer frequencies, achieving exact solutions for the Green's function through complete summation of Feynman diagrams via continued fractions or generalized Ward identities, thereby revealing new spectral modulation effects.
This paper presents a generalized transmon Hamiltonian for Andreev spin qubits that utilizes the flat-band approximation of the Richardson model to enable exact diagonalization, thereby simultaneously capturing quantum dot physics, Josephson effects, and Coulomb repulsion across all parameter regimes for modeling both static and time-dependent processes.
This paper introduces a machine learning model that extends the Gaussian Approximation Potential to include noncollinear magnetic degrees of freedom, enabling efficient ab initio spin dynamics with high accuracy by leveraging rotational symmetries and adiabatic approximations.
This paper investigates relativistic corrections to the electron magnetic moment operator in systems with spin-orbit coupling, introducing the concept of an "abnormal magnetic moment" to highlight ambiguities in conventional decompositions and challenges to standard orbital magnetization theories, while deriving a Kubo formula for the kinetic magnetoelectric effect rooted in the noncommutation of position and magnetic field derivative operators.
