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 proposes a heterostructure of antiferromagnetic MnBiTe and s-wave Fe(Se,Te) superconductor where interlayer sliding-induced ferroelectricity controls the chirality of chiral topological superconductivity by breaking specific symmetries, offering a new pathway for Majorana physics and topological quantum computation.
Using Dynamical Mean-Field Theory, this study demonstrates that a two-orbital attractive Hubbard model with repulsive Hund's exchange exhibits a superconductor-insulator transition at zero temperature and half-filling, where the exchange coupling enhances the effective interaction strength to drive the system toward an insulating state characterized by a vanishing quasi-particle weight, a phenomenon reminiscent of Mott physics despite the dominance of attractive interactions.
This paper predicts a novel structure for low-lying discrete states in the odd-parity sector of a capacitively shunted superconducting qubit containing a trapped quasiparticle, revealing a spectrum fundamentally distinct from the conventional even-parity case across both Coulomb-dominated and Josephson-dominated regimes.
By combining scanning tunneling microscopy, first-principles calculations, and global symmetry analysis on bismuth crystals grown on superconducting V3Si, this study provides direct evidence of higher-order topological bulk-boundary correspondence through the observation of spin-helical hinge state loops and proximity-induced superconductivity, establishing bismuth as a promising platform for realizing topological superconductivity and Majorana quasiparticles.
This paper demonstrates that in sign-changing, fully gapped superconductors, the Fubini-Study metric of electronic Bloch wavefunctions governs the localization length of disorder-induced Andreev bound states, where an increased metric promotes delocalization and drives the system toward a gapless, dirty nodal superconductor state relevant to moiré graphene experiments.
This paper investigates how the odd-even parity of lattice sites and magnetic flux modulate electron transport in an annular Kitaev chain, revealing that asymmetric electrode connections break transmission symmetry and drastically enhance Andreev reflection processes compared to direct transmission, with these parity-dependent effects remaining robust against weak disorder.
This paper presents an analytical study of dilute two-dimensional spin-1/2 Fermi gases with -wave altermagnetic spin splitting and -wave pairing, identifying a ground-state phase diagram that includes unconventional Fulde-Ferrell-Larkin-Ovchinnikov states and topological Bogoliubov Fermi surfaces, thereby highlighting the pivotal role of altermagnetism in enabling exotic superconductivity.
This paper predicts that strong short-range repulsion in a spin-polarized two-dimensional triangular lattice can induce high-temperature f-wave superconductivity by symmetry-forbidding the usual pair-breaking first-order interactions, thereby allowing subleading-order processes to drive pairing with a critical temperature reaching approximately 1% of the bandwidth.
This paper identifies specific electronic band structure properties that enable robust unconventional superconductivity resistant to disorder, demonstrating through kagome and Lieb lattice models that certain sign-changing order parameters can maintain high transition temperatures unlike their counterparts in square and honeycomb lattices.
This study combines NMR, NQR, and AC-susceptibility measurements under pressure to reveal that the Weyl semimetal superconductor 1T-MoTe exhibits a pressure-induced enhancement of the density of states consistent with BCS theory at low pressures, but transitions to a strong-coupling, potentially unconventional superconducting state at higher pressures characterized by the absence of a Hebel-Slichter coherence peak and a non-BCS temperature dependence of the upper critical field.
