This paper proposes a dynamical approach to induce spin splitting and generate pure spin currents in antiferromagnets using optical fields and thermal bath engineering, enabling nonrelativistic spin accumulation without relying on spin-orbit coupling.
Using fuzzy sphere regularization, this paper provides the first unbiased microscopic verification that the topological quantum Hall bilayer transition between the Halperin state and the Moore-Read Pfaffian is driven by a neutral fermion gap closing and is described by a 3D gauged Majorana conformal field theory.
This paper proposes and analyzes a microwave spin-photon interface based on a circular double quantum dot, demonstrating how the interplay of spin-orbit coupling and magnetic flux enables tunable spin-photon coupling, a second-order charge-noise sweet spot, and electrical or magnetic switching capabilities.
This paper experimentally demonstrates that orbital-to-charge conversion via the inverse orbital Hall and Rashba effects dominates over spin-related mechanisms in metallic and semiconductor heterostructures, revealing significant signal enhancements in oxidized copper and distinct orbital diffusion behaviors in titanium and germanium to advance the field of orbitronics.
This study systematically quantifies the cubic magnetocrystalline anisotropy in MnSi and FeCoSi single crystals, revealing that specific low cobalt concentrations in FeCoSi generate sufficient anisotropy to controllably stabilize a low-temperature skyrmion lattice, thereby identifying it as the first chiral metallic system where such a phase is induced by cubic anisotropy.
This paper establishes a unified Poisson Bracket framework for non-collinear antiferromagnetic spin-torque oscillators that utilizes a Terminal Velocity Motion perspective to analytically resolve rapid transient dynamics and hysteretic excitation, while identifying a "Rigid-Body Breaking" mechanism to explain sub-critical current mismatches.
This study experimentally investigates spin and orbital torque phenomena in various normal metal/ferromagnet bilayers using spin-torque ferromagnetic resonance, successfully extracting torque components and providing compelling evidence for orbital torque driven by the orbital Hall effect, including the demonstration of an out-of-plane torque attributed to interfacial mechanisms.
This paper numerically investigates the thermal relaxation of dense gas between parallel plates using two versions of the Enskog equation, revealing that the non-equilibrium free energy decreases monotonically over time only when employing a recently proposed modified Enskog factor, unlike the original formulation.
This paper proposes a data-driven method that applies Koopman analysis to the nonlinear dynamics of variational parameters to predict the ground-state energy of quantum Hamiltonians, offering a way to estimate energies even when the true ground state lies outside the variational manifold.
This paper proposes a dimensional extension method to construct and predict three-dimensional -wave and -wave odd-parity magnets, demonstrating that their unique fourth- and sixth-order nonlinear spin currents, which exhibit unidirectional flow independent of the electric field, serve as definitive experimental signatures for identifying these magnetic phases.
