This paper demonstrates that measurable spin and charge fluctuations in the two-impurity Kondo model serve as entanglement witnesses for quantum criticality, revealing a transition in dominant entanglement partners from conduction electrons to the inter-impurity singlet that is encoded in the quantum Fisher information and accessible through experimental dynamical response functions.
This paper demonstrates that detuned Rydberg ensembles can harness naturally occurring higher-order Kerr nonlinearities, typically considered unwanted perturbations, to rapidly and robustly prepare Schrödinger cat states from vacuum by combining these nonlinearities with controllable linear drives.
This paper demonstrates that applying counterdiabatic driving to the Rice-Mele model enables rapidly quantized topological charge pumping with robustness against disorder and noise, achieved through a derived exact local Hamiltonian that maintains topological protection even in the non-adiabatic regime.
This paper presents multiphysics simulations of semi-insulating GaAs and graphene-enhanced photoconductive antennas to decouple optical carrier dynamics from terahertz radiation, thereby establishing an integrated platform for optimizing future terahertz antenna designs.
This paper demonstrates that flux channeling from a permalloy nanowire can localize and enhance microwave fields by up to 16-fold in sub-300 nm regions, a phenomenon successfully mapped with high resolution using NV center Rabi oscillations without compromising coherence.
This work demonstrates a compact, polarization-invariant radial van der Waals heterostructure metasurface that integrates a high-Q hexagonal boron nitride resonator with a WS monolayer to achieve robust, spatially modulated exciton-photon coupling and enhanced photoluminescence for scalable hybrid photonic-excitonic devices.
This paper theoretically analyzes the terahertz response of electron-hole pairs in semiconductor nanoparticles, demonstrating how the interplay between confinement and Coulomb interaction renormalizes conductivity and proposing a scalable model that bridges the weak and strong confinement regimes using modified Wannier-like wavefunctions.
This study demonstrates time-reversal-symmetry-breaking spin injection from a compensated Mn5Si3 altermagnet in a lateral spin valve, revealing that switching the magnet's time-reversed states alters the detected spin signal due to distinct transport properties for spin-up and spin-down channels.
This paper demonstrates the feasibility and robustness of reflection geometry soft X-ray ptychography as a nondestructive imaging technique capable of achieving approximately 45 nm spatial resolution on bulk or extended specimens, thereby overcoming the sample thickness limitations inherent in traditional transmission-based methods.
This paper identifies a complete kinematic null in a sixfold-driven two-dimensional electron fluid where device symmetry suppresses all local quadratic dissipative terms, thereby isolating a finite kinetic heating mode that enables the precise measurement of effective hydrodynamic coefficients.
