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 study demonstrates that precise control of oxygen content in LaNiO not only tailors phase purity by suppressing intergrown structures but also directly modulates the upper critical field, thereby establishing a comprehensive phase diagram of superconducting properties essential for understanding the mechanism of high- superconductivity in Ruddlesden-Popper nickelates.
This paper investigates superconductivity in twisted WSe bilayers by comparing two theoretical frameworks—a conventional negative -Hubbard model yielding an isotropic -wave gap and a strongly correlated -- model allowing for unconventional symmetries—to evaluate their consistency with recent experimental observations.
This study reports the observation of superconductivity in heavy p-doped germanium point contacts, characterized by a critical temperature of 6 K, a critical magnetic field of 1 T, and an anomalously large superconducting gap ratio, while noting the absence of such effects in similarly doped n-type germanium.
This paper introduces a novel class of topological pairing orders characterized by half-integer monopole charges and Berry phase-enforced symmetry, which emerge from pairing Fermi surfaces with Chern numbers differing by an odd integer and exhibit unique features such as single gap nodes, nontrivial surface states, and fractionalized superfluid velocity relations.
This paper demonstrates that coupling itinerant electrons to noncollinear, frustrated spin textures induces anisotropic Josephson couplings between triplet superconducting vectors, leading to spatially varying pairing orders, anomalous vortices, and a Josephson diode effect.
This paper demonstrates that frustrated spin textures induce anisotropic, spatially inhomogeneous triplet pairing and a Josephson diode effect in superconductors by generating -vector-dependent couplings that break inversion and time-reversal symmetries, distinct from mechanisms driven by spin-orbit coupling.
This study demonstrates that point-contact measurements on trigonal PtBi2 using both normal and ferromagnetic tips significantly enhance the superconducting critical temperature up to 8 K and the critical magnetic field, likely due to strain effects, suggesting the material's potential for realizing topological superconductivity at more accessible temperatures.
This paper utilizes a non-perturbative two-dimensional Yukawa-SYK model to provide a microscopic description of quantum-critical incoherent metals, successfully explaining their unconventional transport properties such as non-Boltzmann resistivity and violations of fundamental physical bounds.
This paper establishes a unified framework based on the Cooper pair quadrupole moment to define superconducting pair size, revealing that in flat-band systems with broken time-reversal symmetry, Berry curvature provides a crucial geometric contribution that, together with the quantum metric, sets a fundamental lower bound on the coherence length.
This paper demonstrates that zero-energy Majorana flat bands in topological superconductors drive the spontaneous emergence of nonuniform superconducting states, specifically pair density waves and phase crystals, which lower the system's free energy by gapping out the flat band and exhibit distinct temperature-dependent stability regimes.
