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~…

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…

Universal low-density power laws of the dc conductivity and Hall constant in the self-consistent Born approximation
Giacomo Morpurgo, Christophe Berthod, Thierry Giamarchi
The dc conductivity tensor of two-dimensional one-band metals with weak pointlike disorder and magnetic field is studied in the self-consistent Born approximation, with special emp…
