This paper proposes a unified paradigm for fabricating superconducting materials under near-ambient conditions using room-temperature liquid metals as dynamic, multifunctional media, offering a versatile, energy-efficient route to diverse superconducting forms while enabling new fundamental studies and data-driven design.
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 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 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 study reports the successful synthesis of a novel bismuth dihydride superconductor, Cmcm-BiH, at high pressures, which exhibits a critical temperature of approximately 62 K at 163 GPa and features a unique open-channel framework where the bismuth host structure, rather than hydrogen, plays the dominant role in driving superconductivity.
This study demonstrates that type-II time-reversal-symmetric Weyl semimetals can host a self-consistent hybrid -wave and -wave superconducting state, where surface Fermi-arc configurations dictate spatial pairing dominance and give rise to second-order topological superconductivity with hinge states.
This paper presents a topology optimization framework based on time-dependent Ginzburg-Landau theory under the Weyl gauge to inversely design the structural geometries of type-II superconductors with superconductor-dielectric/vacuum interfaces, aiming to enhance flux pinning and current density through optimal defect placement.
This study demonstrates that copper-oxide high-temperature superconductors exhibit a zero-field superconducting diode effect indicative of intrinsic time-reversal symmetry breaking, thereby challenging theoretical models that rely on time-reversal-symmetric mechanisms.
This study demonstrates that high-pressure synthesis stabilizes an insulating cubic MgIrH phase coexisting with a hexagonal hydride, confirming theoretical predictions and suggesting that non-equilibrium processing of these structurally similar phases could enable the realization of the predicted high-Tc superconductivity in MgIrH.
