Charge and spin density in the helical Luttinger liquid
N. Traverso Ziani, C. Fleckenstein, F. Crépin +1
The weakly interacting helical Luttinger liquid, due to spin momentum locking, is characterized by extremely peculiar local observables: we show that the density-density correlatio…
Nonperturbative phase diagram of interacting disordered Majorana nanowires
Francois Crépin, Gergely Zaránd, Pascal Simon
We develop a Gaussian variational approach in replica space to investigate the phase diagram of a one-dimensional interacting disordered topological superconducting wire in the str…
Random Rashba spin-orbit coupling at the quantum spin Hall edge
Florian Geissler, Francois Crépin, Björn Trauzettel
We study a one-dimensional helical system with random Rashba spin-orbit coupling. Using renor- malization group methods, we derive a consistent set of flow equations governing the…
