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 theoretically demonstrates a tunable quasiparticle-mediated thermal diode effect in inversion symmetry-broken Weyl Josephson junctions, where an external Zeeman field induces asymmetric thermal currents that can be controlled by the superconducting phase difference and junction length to enable functional thermal switching.
This paper demonstrates that quantum confinement in a two-dimensional nodal topological superconductor can gap out bulk bands while preserving edge states to generate Majorana zero modes, thereby enabling the construction of quasi-one-dimensional topological superconducting phases characterized by a quantized conductance of .
Motivated by recent experiments on rhombohedral tetralayer graphene, this study utilizes the random-phase approximation to demonstrate that density-density interactions drive chiral -wave pairing, successfully predicting the observed superconducting range and distinguishing between finite-momentum chiral states in SC1 and SC2 and zero-momentum spin-singlet superconductivity in SC4.
This paper proposes a method to achieve photo-induced superconducting diode effects by breaking time-reversal symmetry through photon exchange with chiral cavity modes, thereby embedding chirality into the many-body ground state to enable non-invasive, ultrafast control of nonreciprocal responses in quantum circuits.
This paper generalizes Onsager's relation for a single-orbital spinful Hamiltonian to identify two distinct mechanisms of pairing-induced momentum-space magnetism—arising from Cooper pair angular momentum and spin-orbit coupling, respectively—that drive the optical anomalous Hall effect in chiral superconductors, thereby highlighting the essential role of spin degrees of freedom.
This paper investigates enhanced Andreev reflection in lattice junctions, revealing that flat bands and anisotropic dispersion induce directional asymmetry and a Hall-like response in Josephson transport through real-time wave packet dynamics.
Motivated by recent experiments on multiterminal Josephson junctions, this paper proposes a model for the intermediate bias regime that treats the central normal metal as a continuum with nonequilibrium electronic populations, predicting characteristic voltage scales that govern mesoscopic critical current oscillations and bridge interpretations across quartet, topological, and Floquet physics.
This paper demonstrates that Fe-based superconductors with coplanar magnetic order realize an odd-parity magnetic state characterized by -wave spin splitting and a non-linear anomalous Hall effect, while exhibiting a vanishing Edelstein effect in the absence of spin-orbit coupling that is only restored upon its inclusion.
This paper establishes a theoretical framework for the quantum twisting microscope (QTM) as a direct momentum-resolved probe of superconductivity in two-dimensional materials, enabling the measurement of pairing symmetry, coherence factors, and rotational symmetry breaking through planar tunneling between a rotated graphene tip and a sample.
This paper numerically demonstrates that strong Rashba spin-orbit coupling in noncentrosymmetric altermagnets stabilizes a reentrant finite-momentum superconducting stripe phase at low temperatures, driven by anisotropic Fermi surface deformations that facilitate unique pairing mechanisms distinct from conventional helical phases.
