Tailoring the properties of YBa2_{2}Cu3_{3}O7δ_{7-\delta} thin films by 30 keV He+^+ irradiation: An enabling route to superconducting device nanopatterning

This study establishes quantitative fluence thresholds and a practical operational window for 30 keV He+^+ ion irradiation of YBa2_2Cu3_3O7δ_{7-\delta} thin films, demonstrating that controlled defect engineering via Frenkel pair generation—rather than oxygen depletion—enables precise superconducting property suppression and nanopatterning while maintaining structural integrity within a specific fluence range.

Cavity electrodynamics of van der Waals heterostructures

This paper demonstrates that intrinsic plasmonic cavity modes formed by microstructured graphite gates in van der Waals heterostructures can ultrastrongly couple with graphene plasmons, enabling the manipulation of low-energy electrodynamics through on-chip THz spectroscopy despite sub-wavelength device dimensions.

Anomalous terahertz nonlinearity in disordered s-wave superconductor close to the superconductor-insulator transition

This study reveals that in strongly disordered NbN thin films near the superconductor-insulator transition, an anomalous third-harmonic generation signal persists above the critical temperature due to quantum path interference between unpaired electrons and Cooper pairs, which subsequently couples strongly to the driven Higgs mode below the transition.

Interlayer Five-Spin Polaron in Superconducting Bilayer Nickelates

Using resonant x-ray scattering and spectroscopy, this study reveals that superconductivity in bilayer nickelate La2_2PrNi2_2O7_7 thin films emerges in oxygen-stoichiometric regions free of spin density wave order, driven by a robust interlayer five-spin polaron state formed by ligand holes at apical oxygen sites.

Charting the emergent low-dimensional manifold of quantum materials

This paper demonstrates that unsupervised nonlinear dimensionality reduction applied to the Inorganic Crystal Structure Database reveals a hidden low-dimensional geometric manifold that organizes crystalline materials, successfully segregating superconductors and enabling accurate prediction of critical temperatures without knowledge of the underlying pairing mechanism.

Revealing nonvolatile behaviors in magneto-thermal switching using microstructure-controlled superconducting composites

This study demonstrates that nonvolatile magneto-thermal switching in superconducting Sn/Pb composites can be systematically controlled by microstructure engineering via accumulative roll bonding, revealing that the formation of micro-scaled Sn inclusions comparable to magnetic vortices is essential for trapping magnetic flux and enabling this effect.

Exact Dynamics of Topological Order Across a CDW--SPT Transition

This paper investigates the nonequilibrium dynamics of a one-dimensional system transitioning from a charge-density-wave to a symmetry-protected topological phase, demonstrating that while both sudden quenches and slow ramps melt the initial order, only slow ramps successfully establish topological order by suppressing excitation production, whereas quenches fail due to a finite density of defects.
