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.

The authors demonstrate that depositing an ultrathin titanium sacrificial layer on tantalum films acts as a solid-state oxygen getter to chemically reduce the native oxide interface, subsequently removed to yield tantalum coplanar waveguide resonators with internal quality factors exceeding 1.5 million, representing a threefold improvement over untreated devices.
This study demonstrates that field-induced re-entrant superconductivity in Eu-doped NdNiO2 arises from a delicate balance between competing Eu2+ and Nd3+ magnetic ions, whose influence on magneto-transport is activated only upon magnetic polarization.
This work demonstrates the fabrication and characterization of a flux-tunable transmon qubit incorporating an Al/AlO/4Hb-TaS Josephson junction, establishing a viable pathway for integrating van der Waals superconductors into superconducting quantum circuits while revealing distinct discrepancies between spectroscopic and resistive Josephson energy estimates.
This paper proposes that p-wave magnets, a newly discovered class of materials with zero net magnetization and non-collinear real-space spin arrangements, uniquely support an exotic form of Ising superconductivity characterized by a 50:50 singlet-triplet Cooper pair mixture and enhanced pair-breaking resilience, distinguishing them from both conventional antiferromagnets and altermagnets.
This paper proposes the Resonating Entanglement and Confinement Hole Pair (RECHP) theory, a novel pairing mechanism based on entanglement and confinement that provides a comprehensive explanation for the entire phase diagram, including the pseudogap, superconducting dome, and strange metal behaviors, of both electron- and hole-doped high-Tc cuprates.
This paper attributes the unexpected nonzero Josephson currents observed in topological insulator junctions at integer fluxoid states to junction imperfections rather than Majorana zero modes, proposing that low-energy bound states arising from irregularities drive the current and suggesting microwave spectroscopy as a method to experimentally verify this mechanism through distinctive vortex transition selection rules.
Inspired by the extreme field-boosted superconductivity observed in uranium ditelluride (UTe), this paper proposes an effective theory demonstrating how a strong Zeeman field can induce a robust superconducting state with an upper critical field far exceeding the transition temperature, driven by the interplay between superconductivity and metamagnetism.
This study provides microscopic evidence for the Fulde-Ferrel-Larkin-Ovchinnikov (FFLO) state in the multiband superconductor KFeAs through As NMR measurements, revealing a distinct low-temperature phase boundary driven by multiband effects.
This paper predicts that density-balanced, mass-asymmetric electron-hole bilayers can host a unique electron-liquid hole-crystal phase where acoustic plasmons mediate BCS-type superconductivity, offering a tunable platform for experimental realization in van der Waals heterostructures.
This paper establishes a comprehensive symmetry-based classification for predicting topological phonon emergent particles and chiral phonons, leverages this framework to screen over 25 million such modes in a materials database, and provides a dedicated online resource to facilitate the discovery of materials with surface chirality momentum locking and giant phonon magnetic moments.
