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~…
Electronic Sound and Diffusion in Disordered Multiband Metals
Miguel-Ãngel Sánchez-MartÃnez, Blaise Goutéraux, Louk Rademaker +1
Multiband metals can host acoustic plasmons: gapless collective charge excitations involving out-of-phase motion of electrons in different bands, sometimes referred to as 'demons'.…
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…
Tuning correlated states of twisted mono-bilayer graphene with proximity-induced spin-orbit coupling
Jeyong Park, Mingdi Luo, Louk Rademaker +3
We study the correlated ground states of twisted mono-bilayer graphene with and without proximity-induced spin-orbit coupling (SOC) from a transition-metal dichalcogenide layer pla…
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…
