Drosophila of phonon-mediated superconductivity: Full Eliashberg theory of the jellium model
Christophe Berthod, Louk Rademaker, Dirk van der Marel
We present a full numerical solution of the Migdal--Eliashberg equations for the jellium model of phonon-mediated superconductivity. We find very low critical temperatures below 1~…
How twist angle inhomogeneity masks the BKT transition and the order parameter symmetry
Ilaria Maccari, Louk Rademaker, Giulia Venditti
Two-dimensional superconductors, including twisted multilayer graphene, should exhibit a BKT transition, and the -dependence of the superfluid stiffness should distinguish betwe…
Realistic Pearl vortices in thin film superconductors
Aurélien Balzli, Louk Rademaker, Giulia Venditti
We analyze magnetic field profiles of vortices in thin-film superconductors, shedding new light on this old and presumed settled problem. In sufficiently thin films with realistic…
Optimal superconductivity in twisted bilayer WSe where the Van Hove singularity crosses half-filling
Michał Zegrodnik, Waseem Akbar, Andrzej Biborski +1
The recent discovery of unconventional superconductivity has pointed to twisted WSe bilayer as a versatile platform for studying the correlated and topological phases of matter…
Angular momentum of vortex-core Majorana zero modes
Giulia Venditti, Christophe Berthod, Louk Rademaker
Majorana zero modes (MZMs) are highly sought-after states with a possible application in quantum computation. Here, we show that vortex-core MZMs can carry a nontrivial angular mom…
Topological superconductivity with mixed singlet-triplet pairing in moiré transition-metal-dichalcogenide bilayers
Waseem Akbar, Andrzej Biborski, Louk Rademaker +1
We investigate strong coupling topological superconductivity in twisted moiré bilayer WSe. Our approach is based on an effective - model with displacement-field-dependent…
Enhanced superconductivity in FeSe/SrTiO from the combination of forward scattering phonons and spin fluctuations
Louk Rademaker, Gustavo Alvarez-Suchini, Ken Nakatsukasa +2
We study the effect of combining spin fluctuations and forward scattering electron-phonon ({\eph}) coupling on the superconductivity in the FeSe/SrTiO system modeled by a pheno…
Phonon linewidth due to electron-phonon interactions with strong forward scattering in FeSe thin films on oxide substrates
Yan Wang, Louk Rademaker, Elbio Dagotto +1
The discovery of an enhanced superconducting transition temperature in monolayers of FeSe grown on several oxide substrates has opened a new route to high- superconducti…
Aspects of electron-phonon interactions with strong forward scattering in FeSe Thin Films on SrTiO substrates
Y. Wang, K. Nakatsukasa, L. Rademaker +2
Mono- and multilayer FeSe thin films grown on SrTiO and BiTiO substrates exhibit a greatly enhanced superconductivity over that found in bulk FeSe. A numb…
Enhanced superconductivity due to forward scattering in FeSe thin films on SrTiO3 substrates
Louk Rademaker, Yan Wang, Tom Berlijn +1
We study the consequences of an electron-phonon (-) interaction that is strongly peaked in the forward scattering () direction in a two-dimensional supercond…
