By fabricating nano-holes in infinite-layer nickelate superconductors to engineer Josephson junction arrays, this study demonstrates that enhanced phase fluctuations drive a two-stage transition to an anomalous metallic state and reveal hidden intertwined orders, including charge-2e coherence and a reversal of superconducting anisotropy.
This paper theoretically demonstrates that off-resonant circularly polarized light applied to a semi-Dirac normal metal/superconductor junction induces a phase-coherent, transversely asymmetric Andreev reflection, thereby generating a switchable tunneling Hall effect that reverses direction with the light's handedness.
This study demonstrates that stoichiometry-controlled disorder in nanocrystalline NbxSn thin films significantly tunes superconducting properties by inducing thickness-dependent transitions from superconducting to insulating states and altering dimensionality, with Sn-rich compositions exhibiting enhanced sensitivity to disorder and earlier onset of localization compared to stoichiometric films.
This review summarizes recent experimental advances in the non-reciprocal transport phenomena of two-dimensional superconductors, detailing the origins and tunability of second harmonic resistance and the supercurrent diode effect while highlighting their potential applications in high-efficiency rectification and superconducting computing.
This paper defends the authors' established methodology for estimating superconducting shielding volume fractions in pressurized nickelates against recent criticism, arguing that the critics' alternative approach is fundamentally flawed due to its invalid assumption of linear proportionality between diamagnetic moment and shielding fraction in the presence of significant demagnetization.
This study utilizes Ni -edge resonant inelastic x-ray scattering to demonstrate that in compressively strained LaSrNiO thin films, robust double-stripe spin excitations persist across the superconducting regime but collapse upon overdoping to , establishing a direct link between magnetic coherence and superconductivity.
This study demonstrates that multichannel Rashba nanowires with both harmonic and rectangular confinement exhibit robust superconducting diode effects with efficiencies up to ~60%, driven by asymmetric Fulde-Ferrell states that enable high-efficiency nonreciprocal transport and allow for direct topological manipulation of Majorana zero modes via externally injected supercurrents.
This paper presents a newly designed, compact Scanning Tunneling Microscope mounted on a rotatable platform that enables high-precision measurements of electronic density of states under vectorial magnetic fields in arbitrary directions, overcoming the directional limitations of conventional STM setups.
This paper demonstrates that Josephson junctions fabricated on InAs-on-Insulator exhibit extremely weak electron-phonon coupling and robust superconductivity, establishing InAsOI as a superior platform for coherent caloritronics, ultrasensitive bolometry, and gate-controlled thermal circuits.
This paper presents the design, fabrication, and characterization of a 4-pixel NbN hot-electron bolometer integrated with SiN planar waveguides and on-chip fiber-alignment trenches, demonstrating a voltage responsivity of 3800 V/W at 3 GHz for compact, multi-channel cryogenic optical receiver systems.
