Phonon-mode specific contributions to room-temperature superconductivity in atomic hydrogen at high pressures
Ashok K. Verma, P. Modak, Fabian Schrodi +2
We investigate the role of specific phonon mode symmetries for the room temperature superconductivity in atomic hydrogen under large pressure. Using anisotropic Migdal-Eliashberg t…
Cascade of replica bands in flat band systems: predictions for twisted bilayer graphene
Fabian Schrodi, Alex Aperis, Peter M. Oppeneer
We investigate the effect of electron-phonon interactions (EPI) in systems exhibiting one or more flat electron bands close to the Fermi level and a comparatively large phonon ener…
Influence of phonon renormalization in Eliashberg theory for superconductivity in 2D and 3D systems
Fabian Schrodi, Alex Aperis, Peter M. Oppeneer
Eliashberg's foundational theory of superconductivity is based on the application of Migdal's approximation, which states that vertex corrections to first order electron-phonon sca…
Multichannel superconductivity of monolayer FeSe on SrTiO: Interplay of spin fluctuations and electron-phonon interaction
Fabian Schrodi, Alex Aperis, Peter Oppeneer
We investigate the effects of electron-phonon coupling, as well as of spin and charge fluctuations on the superconducting state in a single layer of FeSe on SrTiO substrate. Th…
Charge Density Waves beyond the Pauli paramagnetic limit in 2D systems
Alex Aperis, Georgios Varelogiannis
Two-dimensional materials are ideal candidates to host Charge density waves (CDWs) that exhibit paramagnetic limiting behavior, similarly to the well known case of superconductors.…
Eliashberg theory for spin-fluctuations mediated superconductivity -- Application to bulk and monolayer FeSe
Fabian Schrodi, Alex Aperis, Peter M. Oppeneer
We present a novel method for embedding spin and charge fluctuations in an anisotropic, multi-band and full-bandwidth Eliashberg treatment of superconductivity. Our analytical fram…
