Using the numerical renormalization group method, this study demonstrates that correlated hopping induces asymmetric spin-dependent transport and significantly alters the thermoelectric efficiency of a quantum dot coupled to ferromagnetic leads by modifying Kondo resonance and conductance peak asymmetry.
This paper demonstrates that optimizing the composition and layer thickness of spintronic terahertz emitters using a PtAu alloy significantly enhances THz output power by up to 30% compared to conventional Pt-based devices, establishing it as a high-performance platform driven by a giant spin Hall effect.
This paper proposes a mechanism for electrical uni-directional molecular motors driven by electron current through helical orbitals, introduces a formal definition of helicality to link electronic angular momentum with rotational direction, and predicts that approximate sub-lattice symmetry causes the motor's sense of rotation to remain independent of the current direction.
This study demonstrates that applying a brief in-plane magnetic field to stripe domains in ferrimagnetic Fe/Gd multilayers engineers a dense, near-hexagonal bubble/skyrmion lattice, thereby significantly enhancing the frequency and amplitude of its coherent breathing dynamics and enabling precise control over magnetization behavior and topology.
This paper theoretically proposes a method for cooling electrons by utilizing superconducting tunnel junctions with phase differences and ferroelectric layers, which feature nodal lines that create a divergent density of states and high entropy to facilitate heat removal from an electron bath.
This paper develops a Fokker-Planck framework based on the Landau-Lifshitz-Gilbert equation with Langevin fields to model the thermal fluctuations and spin-wave dynamics of two-dimensional antiferromagnetic systems with uniaxial anisotropy, ultimately applying the theory to describe resistance fluctuations in antiferromagnetic semiconductors.
This review comprehensively introduces the geometrical formalism of strained moiré superlattices derived from linear elasticity theory, explores their application in various twisted 2D materials to predict special patterns, and summarizes recent experimental techniques for realizing and engineering these strain-induced geometries.
This paper presents a Lindblad-based framework for analyzing slowly driven many-qubit thermal machines, demonstrating that geometric heat pumping can surpass the non-interacting Landauer-like bound through qubit interactions and asymmetric bath couplings, thereby offering a pathway to optimize the performance of driven quantum heat engines.
This paper demonstrates that ultra-shallow Ge/SiGe heterostructures with thin SiGe capping layers, fabricated using low-temperature oxide processes to preserve superconducting compatibility, achieve low charge-noise levels comparable to deeper structures, making them a promising platform for prototyping hybrid semiconducting-superconducting devices.
This paper introduces a novel tensor-network methodology that combines real-space Bethe-Salpeter Hamiltonian encoding with a Chebyshev algorithm to efficiently compute excitonic spectra and bound-exciton spectral functions in super-moiré systems exceeding one billion lattice sites, thereby overcoming the computational limitations of conventional approaches for large-scale quantum matter.
