This paper introduces an FPGA-based adaptive spectroscopy technique that achieves sub-second temporal resolution to reveal fast, telegraphic switching and spectral diffusion of parasitic two-level-system defects in superconducting qubits, a regime previously inaccessible to conventional hour-long measurements and critical for understanding gate-level errors.
This paper demonstrates that combining sublattice-staggered and bond-staggered spin-orbit coupling with d-wave altermagnetic order in a two-dimensional system breaks specific symmetries to generate Chern insulator phases and robust, gate-tunable magneto-optical responses, including large optical Hall conductivity and circular dichroism.
This paper demonstrates that charge doping in a gate-controllable MoTe-MoSe heterobilayer cavity can significantly enhance the optical saturation nonlinearity of moiré exciton-polaritons by an order of magnitude through phase space restriction and Pauli blocking.
This study demonstrates that low-power continuous-wave laser illumination can optically switch and deterministically control the magnetic order in few-layer CrSBr via magneto-excitons, offering a promising pathway for applications in magneto-optoelectronic devices.
This paper demonstrates that 1D quantum wires with aspect ratios approaching 1,000 can exhibit fully ballistic coherent interference and discrete quantum states up to 18 m in length, effectively bridging the gap between microscopic quantum systems and macroscopic scales.
Numerical simulations demonstrate that various benzene-ring-containing molecules with hydroxyl groups form thermally stable two-dimensional crystals with extended hydrogen-bonded chains on hexagonal boron nitride substrates, suggesting their potential for developing high-temperature proton-exchange membranes.
This paper presents the fabrication and optimization of centimeter-long, nanometer-thick mechanical resonators that achieve record-breaking room-temperature quality factors approaching 10 billion by combining machine learning-guided design with delicate nanofabrication techniques.
This paper demonstrates that a sudden transition from a homogeneous to an inhomogeneous Dirac velocity in one-dimensional fermions induces an analog Unruh effect characterized by localized particle creation, which persists even for realistic velocity profiles that deviate from the ideal linear Rindler form.
This paper proposes a new mechanism for the nonlinear anomalous Hall effect in tilted two-dimensional gapped Dirac fermion systems, attributing it to a side-jump displacement from Landau-Zener tunneling that complements the conventional Berry curvature dipole and explains experimental observations in the organic Dirac system -(ET)I.
This paper constructs and characterizes an anomalous Floquet topological phase on a negatively curved hyperbolic lattice, demonstrating the existence of chiral boundary modes in bulk quasienergy gaps and introducing a novel puncture-based spectral-flow diagnostic to resolve ambiguities associated with extensive boundaries in finite hyperbolic systems.
