This study demonstrates that resonant excitation of circularly-polarized transverse-optical phonons via a polarization-modulated transient grating induces robust, helicity-defined magnetization reversal in a magnetic overlayer, with switching quality remaining stable under varying ellipticity at resonance but becoming highly sensitive off-resonance.
This paper proposes and demonstrates a new mechanism for generating electric spin and valley Hall effects in buckled 2D hexagonal tunnel junctions, where a perpendicular electric field induces transverse spin and valley currents via backreflection phase rather than Berry curvature, enabling full electric-field manipulation of spin-valley degrees of freedom.
This paper proposes that magnetic dipole coupling between plasmons in metallic layers and magnons in adjacent magnetic van der Waals layers generates Berry curvature and anomalous transport effects, establishing a new framework for topological magnon-plasmonics that includes chiral edge states in skyrmion crystals.
This paper demonstrates that a divergence-free constraint on the polarization field in ferroelectrics induces an emergent gauge symmetry, leading to an unconventional phase transition with an anomalously large anomalous dimension () that defies the standard Landau-Ginzburg-Wilson paradigm.
This paper establishes Wiener-Hopf factorization as a rigorous framework to extend the Amoeba formulation and the generalized Szegö limit theorem from single-band to one-dimensional multiband non-Hermitian systems, thereby clarifying applicability criteria and enabling systematic analysis of symmetry-decomposed spectral potentials.
This Perspective highlights recent advances in single-particle topological band theory by connecting the quantum geometric tensor, delicate and multigap topology, and bundle gerbes to reveal new physical fingerprints and the quantization of non-linear optical responses beyond conventional symmetry-based classifications.
This paper presents a quantitative theory demonstrating that Johnson-Nyquist noise-induced density fluctuations in charge-neutral graphene drive a fluctuating hydrodynamic flow, which generates a size-dependent fluctuation conductivity that diverges logarithmically at zero magnetic field and is rapidly suppressed by external fields, resulting in a giant magnetoresistance effect.
This paper demonstrates that engineered Markovian dissipation can autonomously charge tight-binding quantum batteries into high-energy steady states with large ergotropy, revealing that disorder enhances charging power while the process remains robust against local dephasing noise.
This paper establishes a general theory of boundary-driven non-Hermitian systems that extends non-Bloch band theory to time-periodic settings, demonstrating how boundary Floquet driving can control bulk spectral properties and induce parity-time symmetry breaking through tuning of driving frequency and amplitude.
This paper extends cotunneling theory to general multireference systems, demonstrating that the combination of multireference character and asymmetric tip/substrate couplings generates pronounced asymmetric line shapes in inelastic scanning tunneling spectroscopy, offering a new microscopic explanation for features frequently observed in experiments on correlated molecules.
