This study demonstrates that while chiral molecular potentials in superconducting Josephson junctions have minimal impact on equilibrium charge supercurrents, they induce distinct, anisotropic spin-polarized supercurrents dependent on molecular handedness, thereby establishing spin-polarized Josephson interferometry as a sensitive platform for detecting molecular chirality and advancing superconducting spintronics.
This paper presents a computationally efficient framework for calculating the zero-temperature superfluid weight and magnetic penetration depth from first principles by separating conventional and quantum geometric contributions, thereby enabling large-scale screening of superconductors and validating the method against experimental data for conventional materials.
This paper presents a phenomenological resistively-shunted junction model demonstrating that bias-dependent peaks in differential resistance can suppress odd-numbered Shapiro steps in conventional Josephson junctions, offering an alternative explanation for this phenomenon often attributed to Majorana zero modes.
This paper reports the first direct observation of double-dome superconductivity in magic-angle twisted trilayer graphene, where the suppression of superconductivity near a specific filling factor reveals a distinct phase transition and supports the existence of an unconventional superconducting order parameter linked to an incommensurate Kekulé spiral state.
This study utilizes muon-spin rotation and resistivity measurements to reveal that in the trilayer nickelate LaNiO, pressure suppresses intertwined spin- and charge-density-wave transitions at a uniform rate while oxygen-isotope substitution selectively enhances the charge-density-wave transition, highlighting a distinct coupling between charge and spin orders that differs from bilayer nickelates.
Using muon-spin rotation under high pressure, this study demonstrates that the magnetic properties of the double-layer Ruddlesden-Popper nickelate LaPrNiO, characterized by a pressure-enhanced Néel temperature and stable critical exponents, remain largely unaffected by Pr-to-La substitution, suggesting similar magnetic behavior in the related superconducting compound LaNiO.
This paper proposes a theoretical framework asserting that high-temperature superconductivity in cuprates and nickelates is driven by ionic-bond-mediated electron pairing bridged by oxygen or metal atoms, a mechanism supported by 32 experimental evidences and offering a potential path toward room-temperature superconductivity.
This study demonstrates that oxygen isotope substitution () significantly increases the charge-density wave transition temperature in LaNiO while leaving the spin-density wave transition unaffected, indicating that lattice vibrations drive charge ordering whereas spin ordering is primarily electronic in origin.
This study reveals that the supermoiré lattice in mirror-symmetry-broken twisted trilayer graphene generates unique mini-flat and mini-Dirac bands that host interaction-induced symmetry-broken phases and robust superconductivity, establishing the supermoiré lattice as a powerful new degree of freedom for engineering correlated quantum states.
This paper provides experimental evidence for intrinsic, spin-polarized superconductivity in mesoscopic Fe(Te,Se) rings, characterized by a current-dependent magnetic field and dual flux quantization that is explained by a model combining Rashba coupling with anisotropic out-of-plane interactions.
