This paper presents a method to read the nuclear spin state of DyPc single-molecule magnets using millikelvin spin-polarized scanning tunneling microscopy by analyzing hyperfine-modified telegraph noise statistics and detecting nuclear magnetic resonance directly in the tunneling current, achieving nuclear spin relaxation times exceeding minutes without the need for magnetic field sweeps.
This paper employs an atomistic tight-binding approach to investigate topological bound states in bilayer graphene quantum dots defined by sign-reversing perpendicular electric fields, revealing how atomic structure, field strength, and valley mixing influence discrete boundary states beyond simple continuum models.
This study employs a semi-analytical theoretical model to analyze one- and two-photon absorption spectra in InP/ZnSe nanocrystals, revealing that the valence band offset ranges from 0.85 to 1 eV—exceeding the natural offset due to interfacial electric dipoles formed by preferential Zn-P bonds.
This paper introduces nested feature spectrum topology to establish a fundamental tripartite equivalence among feature, entanglement, and Wilson loop spectra in non-interacting fermionic systems, revealing that topological boundary modes can persist in projected spectra even when the energy spectrum remains gapped.
This paper theoretically demonstrates that in disordered two-dimensional Rashba electron systems, the orbital contribution to the inverse Faraday effect is significantly enhanced by spin-orbit coupling and can rival or surpass the spin contribution, particularly near resonant radiation frequencies.
This paper reanalyzes neutron scattering data from the relaxor ferroelectric PMN to demonstrate that its intrinsic bulk flexoelectricity is comparable to conventional perovskites, suggesting that its unique relaxor properties arise from the suppression of hybridized fluctuation correlations near a Lifshitz-point regime.
This paper introduces a general framework based on "Spatial Localizers" to determine the location of electrons in two- and three-dimensional insulators, successfully extending the concept of Wannier centers to systems with boundaries and disorder while yielding maximally localized states that unify descriptions of atomic and Chern insulators.
This study employs first-principles density functional theory to predict composition-dependent band offsets across the full range of strained Si/Si1-xGex and Ge/Si1-xGex heterostructures, revealing significant nonlinearities and providing analytic fitting expressions to facilitate the design of quantum technology devices.
This paper investigates magnetotransport in time-reversal symmetry-broken Weyl semimetals using a semiclassical Boltzmann approach, revealing that the interplay between momentum-space Berry curvature and skyrmion-induced real-space emergent magnetic fields creates distinct strong-and-weak sign-reversal regimes in magnetoconductivity and generates a unique planar Hall response that serves as a measurable signature of real-space topology.
This paper demonstrates that light-matter coupling beyond the dipole approximation enables cavity photons to interact with fractional quantum Hall edge modes, preserving topological protection in single-mode cavities while inducing backscattering and topological breakdown in multimode cavities, thereby opening new avenues for optical probing and control of FQHE edge excitations.
