Atomic-scale reactivity of the CeO2_2~(100) surface reconstructions by scanning probe microscopy

By combining scanning probe microscopy experiments with first-principles modeling, this study elucidates the atomic-scale structures and reactivity of CeO2_2(100) surface reconstructions, revealing how probe-surface interactions vary between CeO4_4- and oxygen-terminated facets and establishing a framework to distinguish local reduction states that STM alone cannot reliably identify on the former.

Magnetoelastic control of quantum correlations and field sensitivity in a spin-1/2 Heisenberg dimer

This study demonstrates that magnetoelastic coupling in a spin-1/2 Heisenberg dimer enables the control of quantum correlations and enhances magnetic field sensitivity by linking distinct vibrational modes to spin configurations, thereby sustaining nonclassical correlations beyond the entanglement regime and amplifying thermodynamic response in crossover regions.

Time-dependent Berry curvature and quantum metric of Floquet-Bloch states

This paper extends the framework of quantum geometry to periodically driven Floquet systems by introducing time-dependent Berry curvature and quantum metrics, deriving optical sum rules, revealing non-adiabatic charge-pumping mechanisms, and establishing a unified symmetry-constrained framework that connects geometric, topological, and dynamical properties to observable responses like optical conductivity and transport.

Anisotropic transport of Josephson vortices in atomic-layer superconductors on vicinal surfaces

This study experimentally demonstrates that atomic steps on vicinal Si(111)-(7×3)(\sqrt{7}\times\sqrt{3})-In surfaces induce extreme anisotropy in Josephson vortex transport, characterized by a 10310^3-fold difference in mobility and a transition from thermally activated creep to one-dimensional pinning-free flow and quantum tunneling as magnetic field and temperature vary.

Suppressed plasmon excitations, enhanced damping and static screening in Kek-Y strained αT3\alpha-\mathcal{T}_3 model

This paper theoretically investigates the Kek-α\alpha model, revealing that its unique electronic structure—characterized by flat bands and inequivalent Dirac cones—leads to suppressed plasmon excitations and enhanced damping, thereby restricting stable plasmons to small values of the parameter α\alpha or small wave vectors.

Resonantly-enhanced Raman response in graphene-capped bismuthene on SiC

This study demonstrates that resonantly-enhanced Raman micro-spectroscopy serves as a rapid, non-destructive, and spatially resolved ex situ method for characterizing the lattice dynamics and interfacial coupling of graphene-capped bismuthene on SiC, overcoming the limitations of traditional ultra-high vacuum techniques.

Extracting higher-order nonlinearities in nanomechanical resonators using the backbone relation

This paper introduces a robust framework for accurately extracting conservative nonlinearities in high-Q nanomechanical resonators by utilizing backbone curves derived from ringdown measurements, a method that effectively accounts for both symmetry-breaking and non-symmetry-breaking effects while demonstrating superior resilience to frequency fluctuations compared to conventional frequency-response techniques.

Resolving High-Energy States of Interlayer Excitons in MoSe2_2/WSe2_2 Heterostructures

This study utilizes photoluminescence excitation spectroscopy to experimentally resolve a Rydberg-like series of high-energy interlayer exciton states in MoSe2_2/WSe2_2 heterostructures, demonstrating that these states are largely independent of twist angle and align with theoretical predictions based on screened Coulomb interactions.
