This paper investigates the dipolar-exchange spin wave spectrum in thin ferromagnetic bilayers with in-plane magnetization, analyzing how interlayer exchange and dipolar interactions influence the nonreciprocity of emitted magnetic stray fields as a function of layer magnetization orientation and applied magnetic fields.
This paper presents a hybrid experimental approach combining x-ray magnetic circular dichroism (XMCD) with a magnetically modified double-slit interferometer to determine both the real and imaginary parts of the complex refractive index by measuring fringe shifts induced by changes in sample magnetization.
This study demonstrates that the kagome superconductor CsV3Sb5 exhibits spontaneous time-reversal symmetry breaking in both its charge density wave and superconducting states, evidenced by nonreciprocal critical currents that can be deterministically trained by an external magnetic field.
This paper demonstrates that the Hermitian principle of sublattice degeneracy mismatch for flat-band formation extends to non-Hermitian bipartite lattices, giving rise to unique "exceptional flat bands" at and beyond exceptional points that exhibit tunable energies, lifetimes, and biorthogonal eigenmodes with no closed-system analogue.
This paper demonstrates that fabricating C4-symmetric metasurfaces from intrinsically anisotropic ReS2 splits the topological charge of quasi-bound states in the continuum into momentum-separated singularities to create tunable, directionally hybridized exciton-polariton flatbands, establishing a new platform for topologically engineered light-matter coupling.
This paper demonstrates that minimally-twisted gapped bilayer graphene with a triangular network of partial dislocations functions as a plasmonic crystal supporting unique features like flat bands and dissipationless modes, which are analyzed through a novel network-based formalism and simulated for terahertz nano-imaging applications.
This paper presents a comprehensive experimental framework for quantum sensing using a spin ensemble in hexagonal boron nitride, achieving a record coherence time of 80 μs and sub-microtesla magnetic sensitivity at a 10 nm distance, thereby establishing a foundation for next-generation, atomically thin quantum sensors with ultrahigh sensitivity and tunable noise selectivity.
This paper theoretically demonstrates that bond-alternating spin-1 nanographene chains, specifically extended Clar's goblets and passivated [4]-triangulenes, can realize two distinct topological phases (Haldane and dimerized with emergent edge spin-1) and proposes inelastic electron tunneling spectroscopy as the method to experimentally distinguish them.
This review outlines the requirements and architectural strategies for integrating cryogenic electronics into fault-tolerant superconducting quantum computers, offering a first-order resource estimation framework to address the scaling challenges of classical control and readout systems.
This study demonstrates that scaling monolayer transition metal dichalcogenide (TMD) nanoribbons to widths of 30–40 nm significantly enhances transistor performance by reducing contact resistance and improving electrostatics, achieving high on-current densities that make them promising candidates for future ultra-scaled electronics.
