This paper predicts that the unambiguous detection of the superconducting Higgs mode can be achieved in microwave-irradiated asymmetric and transparent Josephson junctions by observing resonant enhancements in the second harmonic of the current-phase relation at zero bias and the AC Josephson current at finite bias.
This paper investigates electric and heat current fluctuations in a two-channel charge Kondo circuit, demonstrating that voltage- and temperature-driven noise ratios exhibit gate-voltage oscillations and logarithmic temperature dependencies characteristic of non-Fermi-liquid behavior, thereby confirming that fundamental relations linking noise to thermoelectric transport persist beyond the Fermi-liquid paradigm.
This paper demonstrates a purely optical, non-destructive readout of the reconfigurable, multistable layered magnetic domain structures in the van der Waals semiconductor CrSBr, revealing a thickness-dependent cascade of intermediate magnetic states that positions the material as a promising platform for spin-optoelectronics and neuromorphic computing.
This study utilizes resonant Raman scattering spectroscopy to characterize the phonon modes and structural symmetries of the charge density wave state in quasi-one-dimensional NbTe, revealing a thermal hysteresis between commensurate and incommensurate phases that suggests potential applications in memory devices.
This paper theoretically derives and validates transparent, quantitative inequalities that serve as necessary and sufficient criteria for identifying and predicting materials exhibiting Axis-Dependent Conduction Polarity (ADCP), a phenomenon where electrical transport is p-type along one crystallographic direction and n-type along the perpendicular direction.
This paper introduces a fully in situ, multi-angle stencil lithography technique to fabricate clean hybrid superconductor-topological insulator charge islands, demonstrating robust proximity-induced superconductivity and Coulomb blockade without post-growth processing.
This paper investigates quantum sensing protocols utilizing Haar random unitary gates within Floquet chaotic dynamics, demonstrating that while asymptotic precision scales linearly (shot-noise limit) in large Hilbert spaces, non-asymptotic regimes offer quantum advantages, and it further establishes that Floquet random quantum circuits effectively mimic global unitary operators in the limit of large local dimensions.
This study demonstrates that ultrafast optical excitation in a WS/CrGeTe van der Waals heterostructure induces an opposite-sign magnetic torque compared to isolated films, driven by interface charge transfer altering magnetic anisotropy and spin current injection, thereby enabling new pathways for ultrafast magnetization manipulation.
This paper demonstrates that coherent microwave driving can resonantly excite localized domain wall oscillations in a ferrimagnetic garnet, enabling efficient depinning and manipulation of magnetic textures through nonlinear dynamics at reduced external magnetic fields.
This paper analytically investigates the optical conductivity of the layered topological semimetal NbSiTe, revealing strong anisotropy in the Drude weight at zero temperature while demonstrating that interband conductivity exhibits a universal linear frequency dependence in both directions, with these findings remaining valid up to experimentally relevant temperatures.
