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 ab initio study of PbTe/Pb heterostructures reveals that while proximity-induced superconductivity with anisotropic pairing emerges, a large Schottky barrier in the normal state likely prevents the formation of Majorana zero modes, challenging the viability of these specific interfaces for topological quantum computing.
Using millikelvin scanning tunneling microscopy on clean-limit lead, this study demonstrates how crystallographic defects can locally tune interband coupling to transform the superconducting order parameter from two distinct gaps to a single merged gap, thereby providing a direct experimental route to visualize and control defect-induced interband proximity effects in multiband superconductors.
This paper investigates the magnetic ground states of bilayer nickelates derived from a hypothetical parent state, demonstrating that the interplay of superexchange and Hund's coupling leads to distinct high-spin, low-spin, or spin-gapped phases, with the high-spin state proving more robust and highlighting the critical need to identify the specific spin state to understand the material's superconductivity.
This paper demonstrates that dissipation in a periodically driven Rashba nanowire coupled to an s-wave superconductor induces both topological and trivial edge-localized Majorana 0- and -modes, significantly modifying the system's topological phase diagram and enabling the creation of topological phases in non-topological setups.
This paper proposes a theoretical pairing model mediated by spin and charge fluctuations, combined with Ising spin-orbit coupling and even-odd parity mixing, to explain the unconventional superconductivity, nodal gap, large upper critical field, and gap anisotropy observed in monolayer transition metal dichalcogenides like TaS.
This paper employs a systematic Schrieffer-Wolff transformation to derive an effective Hamiltonian for Josephson junctions that recovers the conventional cosine potential while simultaneously revealing how Bogoliubov quasiparticles induce correlated dynamics and how higher-order terms naturally generate Josephson harmonics linked to microscopic junction properties.
This study demonstrates that extended two-dimensional hyperuniform patterns comprising tens of thousands of components can be nucleated using the low-temperature vortex structure in pristine Bi2Sr2CaCu2O8 samples as a template, offering a pathway to synthesize next-generation technological devices.
This paper presents a flexible and accurate numerical model for 3D multilayer superconducting devices that validates its ability to enhance qubit anharmonicity and study proximity effects by calculating critical currents and energy gaps without approximating physical layouts or limiting constituent materials.
Using an f-d-p model for UTe2, this study demonstrates that while a point-node-like s-wave pairing state exhibits a reduced but still robust Hebel-Slichter peak, it remains inconsistent with experimental nuclear magnetic resonance measurements.
This paper presents an exact analytical theory for planar ballistic SNS junctions at zero temperature that incorporates phase gradients in superconducting leads, resolving charge conservation issues and revealing a distinct current-phase relation for short junctions that aligns with recent numerical calculations and experimental observations on InAs nanowires.
