Below are the most recent papers in this dynamic area of condensed matter physics, ready for you to explore.
This study demonstrates that the one-dimensional -conjugated polymer PDFHE spontaneously undergoes a Jahn-Teller-like out-of-plane backbone distortion to relieve electronic instability, a phenomenon confirmed by low-temperature scanning tunneling microscopy and density functional theory calculations.
This paper proposes and characterizes a new class of fully gapped, spin-compensated magnetic states called extended s-wave altermagnets, which arise from valley-exchange symmetries and exhibit isotropic spin splitting, spin-selective transport, and pair density wave order.
This paper employs a quantum field-theoretical approach to derive generalized transport formulas for dissipative superconducting systems coupled to multiple Fermi reservoirs, revealing how dissipation reduces steady-state degeneracy and suppresses zero-bias conductance peaks in the Kitaev model.
This paper presents an excitonic theory and numerical simulations demonstrating that in two-dimensional semiconductors at elevated densities, excitonic Rabi oscillations are significantly weakened in Coulomb-dominated regimes and nearly suppressed under linear excitation compared to circular excitation.
This paper develops a microscopic theory demonstrating that spin-orbit scattering in two-dimensional electron systems with smooth disorder and magnetic-field-induced spin polarization generates odd viscosity, which in turn contributes to the anomalous Hall effect.
This paper proposes a novel, spin-orbit coupling-independent mechanism for high-harmonic spin pumping, demonstrating that introducing a static magnetic order perpendicular to a precessing magnetization in purely magnetic structures can generate a cascade of nonlinear spin currents.
This study identifies MoOCl2 as the first naturally occurring hyperbolic van der Waals material, demonstrating that its highly anisotropic electron gas drives unique Fano line shapes in angle-resolved polarized Raman spectra, thereby establishing it as a model system for investigating tunable electron-phonon coupling in hyperbolic materials.
This paper introduces Generalized Equilibrium Propagation and an analytical framework based on Kirchhoff's laws to enable efficient, local gradient calculation for training analog resistor networks using only output-layer information, thereby overcoming the energy and locality constraints of traditional digital machine learning.
This paper derives an exact low-temperature conductance formula for crossed Andreev reflection in quantum dots using Fermi-liquid theory, demonstrating that three-body correlations are essential for accurately capturing corrections to Cooper-pair tunneling, particularly in regimes where superconducting proximity effects dominate over the Kondo effect.
This study utilizes nitrogen-vacancy center-based quantum dephasometry to non-invasively probe and characterize the low-frequency near-field electromagnetic fluctuations and superparamagnetic spin dynamics of a nanoscale CoFeB layer, revealing unconventional temperature-dependent dephasing behavior that provides critical insights for hybrid quantum spintronic applications.
