This review provides a comprehensive and pedagogical comparison of the scattering and nonequilibrium Green's function formalisms for computing phase-coherent quantum transport, demonstrating their mathematical equivalence through linear equation formulations while analyzing the stability, complexity, and practical applications of various numerical algorithms.
This study demonstrates the development of trion-engineered multimodal transistors in bilayer 2D lateral npn heterostructures, which enable precise electrical and optical control over exciton and trion dynamics to achieve dynamic photoresponsivity tuning and advance practical optoelectronic and quantum technologies.
This paper proposes a method using the static structure factor to systematically arrange isotopic defects in a harmonic chain, thereby enabling tunable, frequency-selective control over phonon transmission to achieve either transparency or opacity.
Using a Ginzburg-Landau framework, this study demonstrates that magnetic skyrmions and superconducting vortices in ferromagnetic superconductors form stable bound states exhibiting short-range repulsion and long-range attraction, which drives clustering and offers a theoretical basis for controlling hybrid topological matter.
This paper demonstrates that optimizing the defect density and interfaces of piezoelectric films in high-overtone bulk acoustic-wave resonators enables phonon lifetimes up to 400 μs and a record-high quantum coherence cooperativity of when coupled to superconducting qubits, establishing a new milestone for circuit quantum acoustodynamics devices.
This paper develops a gauge-invariant geometric perturbation theory for Bloch states that constructs a hierarchy of dressed dispersion and connection terms to describe nonlinear transport, specifically deriving the fully coherent, purely geometric third-order response to a uniform electric field.
This paper demonstrates that while spin-independent dissipation eliminates second-order exceptional points in finite-gap superconducting double-quantum-dot Josephson junctions, the combination of spin-dependent dissipation from a ferromagnetic reservoir and magnetic flux tuning not only stabilizes these singularities but also enables the formation of third-order exceptional points with cubic-root scaling, all while maintaining continuous Josephson currents across the non-Hermitian singularities.
This paper establishes a unified geometric framework for weak topological phases by demonstrating that edge states, corner modes, and compact localized states correspond to exceptional points and curves within the complex-momentum space of an analytically continued Bloch Hamiltonian.
Using scanning tunneling microscopy/spectroscopy combined with ab initio simulations, this study identifies a b-axis-aligned double sulfur vacancy as a common intrinsic defect in CrSBr and characterizes its structural and electronic signatures near the valence band edge.
This study demonstrates that in superconducting NbSe2, Meissner currents induced by an in-plane magnetic field selectively Doppler-shift Bogoliubov quasiparticle spectra at charge density wave vectors, thereby driving a symmetry-breaking transition in CDW modulations and enabling momentum-space engineering of intertwined electronic phases.
