Coexistence of near- Flat Band and Van Hove Singularity in a Two-Phase Superconductor
Quantum many-body systems, particularly, the ones with large near-EF density states, are
well known for exhibiting rich phase diagrams as a result of enhanced electron correlations …

Multiple superconducting phases in heavy-fermion metals
Symmetry breaking beyond a global U (1) phase is the key signature of unconventional
superconductors. As prototypical strongly correlated materials, heavy-fermion metals …

Role of the Berry curvature on BCS-type superconductivity in two-dimensional materials
F Simon, M Gabay, MO Goerbig, L Pagot - Physical Review B, 2022 - APS
We theoretically investigate how the Berry curvature, which arises in multiband structures
when the electrons can be described by an effective single-band Hamiltonian, affects the …

Nonreciprocal superconductivity
M Davydova, M Geier, L Fu - arXiv preprint arXiv:2407.01681, 2024 - arxiv.org
We introduce the notion of nonreciprocal superconductors where inversion and time-
reversal symmetries are broken, giving rise to an asymmetric energy dispersion. We …

Superconducting meron phase in locally noncentrosymmetric superconductors
A Minamide, Y Yanase - arXiv preprint arXiv:2405.13507, 2024 - arxiv.org
Theory of the superconducting parity transition is extended by incorporating the vortex
degree of freedom. We employ the bilayer Rashba model representing locally …
