Using microwave spectroscopy on a high-quality ferromagnet, researchers observed an unexpected Fano resonance that reveals the existence of long-lifetime magnon pairs through their coherent coupling with Kittel magnons via three-magnon interactions.
This paper employs time-dependent Landauer-Büttiker transport theory to analyze current cross-correlations in Majorana zero mode nanowire junctions, deriving a heuristic formula for electron traversal times and proposing a time-resolved transport measurement to experimentally distinguish genuine Majorana bound states from spurious ones.
This study establishes RuO as a weakly correlated Fermi liquid by revealing a previously undetected quadratic temperature dependence in its electric resistivity that follows Kadowaki-Woods scaling, while thermal transport measurements show a deviation from the Wiedemann-Franz law at finite temperatures, providing critical data for first-principles theories of electron-electron scattering in metallic oxides.
This paper demonstrates a flux-modulated scheme for two strongly nonlinear superconducting oscillators that enables the selective activation of distinct interaction regimes—including photon-hopping, two-mode squeezing, and cross-Kerr interactions—to facilitate the analog simulation of arbitrary spin systems and the exploration of driven-dissipative dynamics in previously unexplored parameter spaces.
This paper reviews recent progress and presents original results on applying quantum geometry, including Zeeman and information geometries, to -wave magnets () to derive universal analytic formulas for their anomalous transport, magneto-optical, and oscillation phenomena.
This paper explores the connection between quantum geometry and measurable phenomena in non-Hermitian systems, demonstrating how concepts like adiabatic potentials and Wannier state localization are governed by quantum geometry and proposing a method to experimentally measure the non-Hermitian quantum metric through time-periodic modulation.
This paper demonstrates the first quantitative vector-field magnetometry of a synthetic three-dimensional antiferromagnet using nitrogen-vacancy scanning probe microscopy under ambient conditions, successfully characterizing nanoscale static and dynamic spin textures, domain walls, and thermal spin-wave noise with exceptional sensitivity and spatial resolution.
This paper demonstrates that using a suitably thin hBN back-gate dielectric in Kelvin probe force microscopy (KPFM) effectively mitigates non-linear electrostatic doping effects, enabling accurate measurement of Fermi levels and bandgaps in back-gated 2D semiconductors like WSe2.
This paper presents a novel laser-excitation system integrated into a scanning transmission electron microscope (STEM) that enables time-resolved nanoscale thermal transport measurements with ~50 ns temporal resolution, successfully determining local thermal conductivity and heat capacity in amorphous carbon films via ultra-high-resolution electron energy-loss spectroscopy.
This paper investigates the spin dynamics of a Dzyaloshinsky-Moriya trimer by employing a unified Hamiltonian framework and the modified Gisin-Schrödinger equation to bridge quantum and semiclassical regimes, ultimately analyzing the evolution of spin motion and chiral dynamics across these different levels of approximation.
