This paper experimentally demonstrates period doubling and higher multiplicities (up to ) in a driven single spin-1/2 system using nitrogen-vacancy centers in diamond, supported by theoretical analysis that identifies low-frequency modulations as unique proxies for approaching these period--tupling states.
This paper establishes a unified thermodynamic theory of local orbital magnetization based on a perturbative expansion of the magnetic-field-dependent local density of states, which resolves sublattice-scale magnetic textures in diverse geometries and introduces a novel local Berry curvature to characterize magnetic-field-induced electronic redistribution and bulk topology in finite systems.
This paper presents a comprehensive, symmetry-based theory of MgB superconductivity using compact analytic models to demonstrate that quantum-geometric effects in the bond-centered kagome lattice drive a dominant electron-phonon coupling enhancement, which increases the critical temperature upon light electron doping.
This paper demonstrates that under strong magnetic fields and periodic potentials, two-dimensional electron systems can form integer and fractional quantum Hall crystals, including anyon crystals stabilized at odd-denominator filling fractions, which emerge from a mean-field analysis of bosons with attached flux quanta as supersolids that undergo vortex-anti-vortex nucleation to realize crystalline anyon ordering.
This paper proposes a unified framework describing various anyon-driven quantum phases, including diverse superconducting states and itinerant ferromagnets, as competing instabilities of a Fermi surface of charge- "quarks" coupled to an Chern-Simons gauge field, thereby offering a new perspective on the recently observed superconductivity near fractional quantum anomalous Hall states in twisted MoTe bilayers.
This paper demonstrates that elliptically or circularly polarized light can dynamically switch zero-net-magnetization odd-parity magnets (such as -wave and -wave states) into finite spin-polarized states with controllable Chern numbers, offering a promising optical route for spintronics and quantum information applications.
This paper proposes a probabilistic protocol that entangles distant nitrogen-vacancy centers via a magnonic bus by coupling them to a non-computational transition, thereby breaking the typical tradeoff between coupling strength and entanglement fidelity to achieve near-unit fidelity even with weak coupling.
This paper presents an efficient, two-stage analytical framework based on a solvable modified Kratzer model to retrieve fundamental material parameters of monolayer transition-metal dichalcogenides directly from optical and magneto-optical exciton spectra, enabling the accurate prediction of excitonic properties without the need for numerical fitting or matrix diagonalization.
This paper proposes a minimal quantum-optical scheme using structured light to generate hybrid entanglement between photon polarization and electronic orbital angular momentum in a semiconductor quantum disk, demonstrating via master-equation analysis that a heralded single-photon emission can effectively map the electronic state to a target entangled configuration while accounting for realistic decoherence mechanisms.
This study demonstrates that in ultrathin, disordered NbN films, increasing kinetic inductance drives a crossover from conventional gap-dominated electrodynamics to a phase-fluctuation-dominated regime characterized by BKT transitions and anomalous power-law suppression of superfluid stiffness, a behavior governed by the ratio of superfluid stiffness to pairing energy and linked to nanocrystalline twin-domain disorder.
