Superconductivity is a fascinating state of matter where materials conduct electricity without any resistance, often defying our everyday expectations of how energy behaves. Researchers in this field explore the quantum mechanics behind these phenomena, seeking new materials that can operate at higher temperatures or under more practical conditions. This work holds the promise of revolutionizing everything from power grids to medical imaging devices, making the invisible world of quantum physics feel increasingly tangible and useful.

This paper reports the discovery of ambient-pressure superconductivity with an onset temperature of approximately 63 K in compressively strained (La,Pr)₃Ni₂O₇ thin films, achieved via a giant-oxidative atomic-layer-by-layer epitaxy method that enhances interlayer coupling and links the high transition temperature to strange-metal behavior.
This paper reports the discovery of bulk superconductivity with a transition temperature of 0.7 K in the structurally pristine kagome metal YRu3B2, as confirmed by magnetization, resistivity, and heat-capacity measurements.
This paper develops a symmetry-adapted multipolar theory for noncentrosymmetric crystals in the strong spin-orbit coupling limit, revealing that multipolar interactions for reshape Fermi surfaces and create distinct total-angular-momentum textures that lead to nonmonotonic, enhanced Edelstein effects in heavy-element materials.
This study demonstrates that epitaxial La2.82Sr0.18Ni2O7 thin films exhibit intrinsic three-dimensional bulk superconductivity with a sharp transition at 31.6 K, where the in-plane upper critical field is significantly suppressed by spin-paramagnetic pair breaking near the Pauli limit, resulting in a reduced anisotropy ratio of approximately 1.34.
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 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 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 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 demonstrates that a temporal Berry phase in a clean U(1) nonlinear sigma model induces space-time anisotropic vortex interference, leading to a quasi-disordered phase with short-range spatial order and persistent temporal coherence that shares the essential correlation properties of the disordered Bose Glass phase, thereby suggesting a unified topological origin for glassy behavior in phase-fluctuation-driven superfluid transitions.
This paper demonstrates that the transition between and superconducting states in a two-band model with nonmagnetic impurities evolves from a smooth crossover at high temperatures to a first-order phase transition at low temperatures, thereby establishing a critical end point on the temperature-impurity scattering rate phase diagram that suggests the possibility of a quantum phase transition.
