We consider a finite-size topological Josephson junction formed at the edge of a two-
dimensional topological insulator in proximity to conventional superconductors and study …

We study a superconductor Josephson junction with a Bogoliubov Fermi surface, employing
McMillan's Green's function technique. The low-energy degrees of freedom are described by …

We investigate odd-in-time—or odd-frequency—pairing of fermions in equilibrium systems
within the particle-number-conserving framework of Penrose, Onsager, and Yang, where …

We review recent theoretical progress in understanding spatially uniform s-wave
superconductivity which arises from a fermion–fermion interaction, which is repulsive on the …

In previous theoretical studies of phonon-mediated superconductors, the electron-phonon
coupling is treated by solving the Migdal-Eliashberg equations under the bare vertex …

We study the pairing of fermions by an interaction consisting of a Hubbard repulsion,
mimicking a screened Coulomb potential, and a dynamical phonon-mediated attraction. For …

We propose an approach for investigating the many-body effects on the phonon spectrum in
an electron-phonon coupled system by taking into account the electron self-energy and …
