This paper demonstrates through computer simulations and non-equilibrium Green's function calculations that an externally applied electrical bias can switch the sign of out-of-equilibrium interlayer exchange coupling in a ferromagnetic tri-layer system, particularly when strongly confined quantum well states are present, thereby enabling control over the magnetic configuration between parallel and anti-parallel states.
This paper demonstrates the controlled fabrication of VO nanocylinders with tailored phase transition hysteresis via lithographic patterning and dewetting, offering a scalable pathway for energy-efficient neuromorphic photonic memory devices.
This study demonstrates that all-optical thermal manipulation using laser pulses can induce demagnetization, controlled domain wall motion, and reversible 90° switching of antiferromagnetic domains in NiO/Pt and CoO/Pt thin films via thermal gradients, offering a current-free pathway for ultrafast antiferromagnetic spintronics and non-volatile memory applications.
This paper establishes a fully field-theoretic derivation of chiral edge modes in abelian Chern-Simons theory on a strip by identifying general local boundary conditions that yield opposite Kac-Moody algebras and velocity-independent edge dynamics through a holographic-like bulk-boundary matching.
This paper demonstrates an ultrafast nonlinear Hall effect in centrosymmetric black phosphorus by dynamically breaking inversion symmetry with femtosecond light pulses, revealing a polarization-selective, 300-fs-lasting current generation mechanism supported by momentum-resolved photoemission spectroscopy and *ab-initio* calculations.
This paper demonstrates that utilizing matrix product states with an optimized index ordering and a dimensionless formulation enables efficient, high-fidelity solutions to the Peierls-Boltzmann transport equation for crystalline silicon across various transport regimes, achieving sublinear computational scaling and a tenfold reduction in time compared to traditional finite volume methods.
This paper demonstrates that the exact solutions for two interacting electrons in a strong magnetic field organize into "sub-Landau levels" defined by relative angular momentum, providing a microscopic framework for constructing many-electron trial wavefunctions that explain the emergence of correlated phases in quantum Hall systems.
This paper demonstrates that quantum corrections to electron dynamics in a circularly polarized electromagnetic field generate an anomalous radiation reaction force acting perpendicular to the electron's velocity, a phenomenon arising from one-loop QED effects that has no classical analog.
This paper demonstrates that in a disordered Su-Schrieffer-Heeger chain near the topological delocalization transition, the hybridization of topological domain wall zero modes with stretched-exponential spatial decay drives an anomalous logarithmic scaling of ac conductivity at criticality.
This paper proposes that aligning twisted bilayer graphene with specific commensurate insulating substrates induces intervalley coupling and spin-orbit interactions, transforming the system into a geometrically frustrated four-band model that hosts topological flat bands with high spin Chern numbers near the magic angle.
