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 demonstrates numerically that the vortex core structure in spin-triplet superfluid He is significantly altered near a surface due to the interplay between spin-orbit interaction and surface symmetry breaking, creating an inhomogeneous vortex line that differs fundamentally from its bulk counterpart and cautioning that surface-limited observations may not reflect the true bulk pairing nature.
This paper theoretically demonstrates that VO-based altermagnets, modeled via a six-orbital framework, robustly exhibit spin-polarized specular Andreev reflection at superconductor interfaces, offering a viable platform for generating energy-entangled electron pairs through a proposed multiterminal detection setup.
This paper proposes and analytically derives a mechanism for generating phonon angular momentum in mixed-parity and spin-orbit-coupled s-wave superconductors driven by a supercurrent, while also providing a physical interpretation of the effect.
This paper demonstrates that a Bloch-like domain wall in a ferromagnetic racetrack enables precise control over Josephson coupling between superconducting electrodes, allowing for tunable critical currents, $0$-- transitions, and complex supercurrent patterns that establish domain walls as viable control elements for superconducting racetrack memory devices.
This study reports the ambient-pressure superconductivity of monolayer-bilayer and bilayer-trilayer Ruddlesden-Popper nickelate superstructures with transition temperatures exceeding 46 K, revealing that the emergence of superconductivity is intrinsically linked to specific Fermi surface topologies featuring Ni -derived hole-like bands.
This paper predicts that superconductor/antiferromagnet/superconductor heterostructures enable ultrastrong magnon-photon coupling at terahertz frequencies, where magnetic fields tune the interaction between one or both magnon modes and photons to create highly tunable magnon-polaritons with group velocities reaching several tenths of the speed of light.
This paper presents a theoretical framework and experimental verification demonstrating that 2D SQUID arrays can function as absolute magnetometers with ultra-high performance by utilizing "synthetic area spread" generated through bare superconducting loops, thereby eliminating the need for physically incommensurate loop areas.
Using cellular dynamical mean-field theory, this study of the two-dimensional Hubbard model reveals that superconducting pairing in cuprates is driven by low-frequency pair-forming processes mediated by the superexchange interaction, while high-frequency pair-breaking processes eliminate the direct effects of the interaction strength .
This paper investigates a non-Hermitian Josephson junction to identify and propose an experimental protocol for detecting a novel supercurrent contribution arising from the phase derivative of Andreev level broadening, demonstrating that this fingerprint of non-Hermiticity can be observed even in the absence of exceptional points.
This study demonstrates that thermally-activated epitaxy at temperatures exceeding 1000°C enables the reproducible growth of high-quality NbO films with superior structural and transport properties, thereby establishing a prototypical understanding of NbO's electrical behavior and highlighting the utility of high-temperature synthesis for refractory metal compounds.
