This tutorial article bridges the gap between the mathematical theory of geometric phases and experimental nanophotonics by demonstrating how structured light interacting with nanostructures can exhibit similar phase laws arising from fundamentally different underlying geometries compared to conventional optics.
This paper determines the ultimate limit of cavity-induced electron mass renormalization by numerically evaluating the Feynman path integral for a 2D electron, revealing that the maximum effect corresponds to the Landau-Pekar polaron in a planar geometry due to field-mediated interactions with the cavity mirrors.
This paper reports the achievement of record-breaking low-temperature electron mobility exceeding cm V s in InAs quantum wells grown on insulating InP substrates by optimizing a convex compositional grading profile in an InAlAs metamorphic buffer, thereby enabling thick, Ga-free layers ideal for topological superconductivity research.
This paper investigates quantum heat transport in noncommuting coupled spin systems using a quantum dressed master equation, revealing that noncommuting coupling enables robust negative differential thermal conductance in weak coupling regimes and pronounced thermal rectification in strong coupling regimes, while a three-terminal extension demonstrates the system's capability to function as a high-performance quantum thermal transistor with significant heat amplification.
This paper proposes a new class of nodal-line semimetals characterized by non-quantized Berry phases that induce Landau level splitting and unique surface state localization, thereby extending the conventional topological framework of these materials.
This Perspective reviews diverse magnetic metal electrode materials for magnetic tunnel junctions, arguing that effective spin polarization is a complex, interface-resolved transport property rather than a simple bulk scalar, and outlines strategies to harness emerging magnetic orders like altermagnets for robust, electrically addressable spintronic applications.
This paper investigates how avoided crossings in the many-body spectrum of finite spin-boson systems constrain adiabatic state preparation times and induce non-monotonic behavior in local observables, providing essential benchmarks for quantum simulation and control.
This study reveals that bimetallic nanoparticles, exemplified by Au-Rh systems, can form thermodynamically controlled subnanometer "shell-dimer" overlayers driven by elemental immiscibility and lattice mismatch, where a delicate balance of surface, interfacial, and strain energies dictates the stability and atomic-scale structure of the overlayer.
This paper introduces a real-axis least-squares bath discretization method within the driven Liouville–von Neumann framework for superconducting reservoirs, which significantly reduces computational costs while accurately resolving transient coherence, nonlinear transport features, and damping-induced decay rates in quantum-dot Josephson junctions without the artificial smearing typical of previous finite-broadening approaches.
This study reports the discovery of correlated electronic states in the conduction bands of near-AA-twisted bilayer MoS, revealing a twist-angle-dependent phase diagram where Pomeranchuk-like electronic localization persists above 100 K, distinguishing it from similar phenomena in graphene systems.
