This paper reports the observation of quasi-periodic triangular patterns of spatially indirect excitons in a MoSe/WSe heterostructure and attributes their formation to a micrometer-scale elastic wrinkling instability confirmed by Föppl-von Kármán theory.
This study provides evidence for spin swapping in magnetic heterostructures with Rashba interfaces by demonstrating that the opposite signs of transverse resistance modulation in Cu/Bi2O3 and Ag/Bi2O3 systems directly correlate with the opposing spin/charge interconversion efficiencies of their respective interfaces.
This paper develops a Lifshitz-Kosevich framework for topological flat bands, demonstrating that their anomalous Landau levels exhibit field-dependent thermal damping which directly measures the quantum metric, thereby establishing quantum oscillations as a probe for flat-band quantum geometry.
This paper theoretically demonstrates that in two-dimensional -wave magnets with Rashba spin-orbit coupling, parity-driven mechanisms induce a spatial decoupling between isotropic out-of-plane and directionally tunable in-plane exchange interactions, while a competition between nodal geometry and the Rashba gap generates an anomalous, dimension-reducing decay in the in-plane Dzyaloshinskii-Moriya interaction.
This paper identifies a novel time-reversal-invariant topological metallic phase in a bilayer Lieb lattice characterized by a quantized layer-resolved pseudo-spin Chern number, where specific orbital-angular-momentum-dependent couplings tune the system between semimetallic and metallic regimes while preserving distinct, asymmetric edge states that can be selectively manipulated via interlayer and intralayer interactions.
This paper derives an extended Landau-Lifshitz equation for nanomagnets with surface anisotropy using a spin coherent-state path integral formalism, demonstrating that eliminating fast transverse spin fluctuations leads to surface-induced magnetization nutation and renormalized damping effects that are experimentally measurable via ferromagnetic resonance.
This paper develops a comprehensive theory of electron spin relaxation in structured phononic reservoirs, such as quantum dots in phononic waveguides, revealing that while relaxation rates can be significantly enhanced compared to bulk materials, they can also be suppressed by orders of magnitude due to phononic bandgaps and symmetry selection rules, with complex non-Markovian dynamics emerging near van Hove singularities.
This paper demonstrates that bismuth-doped NaBiF:Er,Yb upconversion particles offer superior quantum yield, dual-wavelength tunable emission, and sub-diffraction capabilities, establishing them as advanced, high-contrast multi-functional biomarkers for deep-tissue optical imaging.
This paper theoretically explores a new phase-diffusive regime in current-biased Josephson junctions embedded in circuits with anomalous dissipation, revealing that such environments significantly enhance quantum escape processes at low temperatures and offer promising applications for microwave photon detection and dissipative quantum annealing.
This paper demonstrates that moiré-engineered graphene Josephson junctions can sustain phase-coherent superconductivity up to 6 Tesla by utilizing dispersive magnetic Bloch bands within the Hofstadter spectrum to overcome the magnetic field limitations that typically suppress conventional Josephson transport.
