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 numerically investigates chiral Andreev edge states in a quantum Hall system proximitized by a superconductor, demonstrating how Andreev reflection induces edge mode mixing, how Zeeman splitting preserves spin orthogonality, and how Rashba spin-orbit coupling combined with magnetic fields drives complex spin mixing and robust transmission degeneracies.
This paper demonstrates that momentum-dependent altermagnetic spin splitting in two-dimensional metals suppresses singlet pairing to stabilize highly anisotropic equal-spin triplet superconductivity, which generates spin-resolved Majorana boundary states with characteristic spin-edge locking without requiring external magnetic fields.
This paper investigates field theory models of holographic superconductors in two dimensions where order parameter condensation is induced by Robin boundary conditions, utilizing modular invariance to analytically reproduce holographic phase diagrams and matching near-critical behavior with Ginzburg-Landau theory while exploring fractional Little-Parks effects through vortex models.
This first-principles study predicts that the RbH system can host high-temperature superconductivity with critical temperatures up to 111 K at remarkably low pressures (as low as 10 GPa) when lattice quantum anharmonic effects are incorporated.
This study utilizes RIXS measurements to demonstrate that while superconducting PrNiO2 and insulating CaCuO2 share most spin and orbital properties despite their different charge-transfer energies, they exhibit distinct behaviors in the dispersion of Ni-dxy orbital excitations due to orbital superexchange coupling.
This paper presents an ensemble XGBoost machine learning approach trained on a curated hydride dataset to effectively screen and identify promising ternary superconducting candidates, such as Ca-Ti-H and Li-K-H, at high pressures without requiring prior structural information.
This paper reveals that triplet superconductors exhibit a non-relativistic spin-orbit coupling induced by the triplet order parameter, which entangles orbital and spin motions to enable electric-field-driven spin polarization (Edelstein effect) and efficient nonlinear generation of DC spin currents without requiring relativistic spin-orbit coupling.
Using ultra-low temperature scanning tunneling microscopy and electrical transport measurements, researchers observed a nodeless, flat-bottom U-shaped superconducting energy gap in ambient-pressure (La,Pr)₃Ni₂O₇ thin films with an onset Tc above 40 K, providing new insights into high-Tc nickelate superconductivity and potential hints for liquid-nitrogen-temperature superconductivity.
This paper establishes the theoretical and experimental relationship between reactive magnetron sputtering parameters and the properties of ultrathin NbN films on various substrates, ultimately identifying specific film characteristics (a critical temperature near 9 K and sheet resistance of 400 /sq) as optimal for fabricating ultrahigh-performance superconducting nanowire single-photon detectors.
This paper predicts a new family of ambient-pressure superconducting boron-rich compounds (XB) composed of interconnected B icosahedral superatoms and electropositive guest atoms, which exhibit critical temperatures up to 42 K driven by broad electron-phonon coupling across both intra- and inter-superatomic vibrations.
