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 systematically classifies strain-induced piezomagnetic effects in collinear altermagnets through symmetry analysis and first-principles calculations, revealing distinct band-filling and exchange-driven mechanisms while demonstrating how strain can drive the transition from unitary to non-unitary triplet superconductivity.
This paper presents a generalized set of self-consistent Gor'kov-Hedin-Baym equations that integrate spin-dependent electron-electron and electron-phonon interactions, relativistic effects, and lattice correlations to provide a unified framework for studying non-trivial superconductivity in candidate materials, which yields a generalized Migdal-Eliashberg theory and naturally incorporates ladder vertex corrections.
This paper predicts a novel dynamical proximity effect in topological superconductor/ferromagnetic insulator heterostructures where spin-momentum locking facilitates the coupling of ferromagnetic magnons and superconducting Nambu-Goldstone modes into hybrid excitations, enabling the interconversion of spin and spinless signals for advanced superconducting spintronics.
This paper reveals that in nonequilibrium superconductors, a supercurrent initiated by a probe field can paradoxically grow in time during the cooling phase due to momentum-relaxing scattering of Bogoliubov quasiparticles by impurities and phonons, leading to experimental signatures such as an ultrafast Meissner effect and optical reflectivity exceeding unity.
Through systematic experiments on Josephson junctions in a true resistive environment, this study resolves the long-standing debate on the Schmid-Bulgadaev transition by confirming that the crossover from superconducting to insulating behavior occurs at the theoretically predicted quantum resistance of , even at non-zero temperatures.
Using s-wave superconducting scanning tunneling microscopy, researchers identified a topological quasiparticle surface band and its specific conductance evolution in , providing evidence for a non-chiral, odd-parity, time-reversal-invariant superconducting order parameter.
Using finite-temperature tensor network simulations on the -- model, this study reveals that superconductivity in underdoped cuprates evolves from pairing correlations localized on intermediate-temperature hole clusters to a coherent, system-wide state in the ground-state stripe phase, providing a microscopic explanation for experimental observations of local pairing above and charge clustering.
This paper demonstrates that incorporating an electroluminescent GaP inhomogeneous phase into MgB2 enables optically activated superconductivity, where in situ light emission enhances the electron-phonon coupling to raise the critical temperature by ~1.4 K while simultaneously improving the critical current density by ~69% through structural pinning.
This paper reports the fabrication and successful integration of scalable, oxide-free Nb/NbN and Nb/TiN multilayer nanobridge Josephson junctions into dc SQUIDs, utilizing a geometrically defined weak link to engineer superconducting properties without relying on focused ion beam milling or tunnel barriers.
Muon-spin rotation measurements on PrNiO reveal that the oxygen-isotope effect on the spin-density wave transition remains invariant under hydrostatic pressure, providing evidence that the intertwined order in this trilayer nickelate is predominantly driven by electronic interactions rather than electron-phonon coupling.
