The occurrence of superconductivity in doped SrTiO3 at low carrier densities points to the
presence of an unusually strong pairing interaction that has eluded understanding for …

Identifying the microscopic mechanism for superconductivity in magic-angle twisted bilayer
graphene (MATBG) is an outstanding open problem. While MATBG exhibits a rich phase …

A superconductor emerges as a condensate of electron pairs, which bind despite their
strong Coulomb repulsion. Eliashberg's theory elucidates the mechanisms enabling them to …

Motivated by the observation of superconductivity in SrTiO 3 and Bi, we analyze phonon-
mediated superconductivity in three-dimensional systems at low carrier density, when the …

The experimental observation of superconductivity in doped semimetals and
semiconductors, where the Fermi energy is comparable to or smaller than the characteristic …

Electrons driven coherently by laser light can exhibit nonperturbative geometric effects.
Drastic deformation and gap openings of the electrons' Floquet bands occur at one-photon …

The microscopic pairing mechanism for superconductivity in magic-angle twisted bilayer
graphene remains an open question. Recent experimental studies seem to rule out a purely …

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

Recent advancement in laser technology has opened the path toward the manipulation of
functionalities in quantum materials by intense coherent light. Here, we study three …

We examine the effect of repulsion on superconductivity in a three-dimensional system with
a Bardeen-Pines-like interaction in the low-density limit, where the chemical potential μ is …
