Backscattering in a helical liquid induced by Rashba spin-orbit coupling and electron interactions: locality, symmetry, and cutoff aspects
Maxim Kharitonov, Florian Geissler, Björn Trauzettel
The combination of the time-reversal-symmetric single-particle backscattering field (commonly known as Rashba spin-orbit coupling) and non-backscattering electron interactions is g…
When intuition fails in assessing conditional risks: the example of the frog riddle
Daniel Hetterich, Florian Geissler
Recently, the educational initiative TED-Ed has published a popular brain teaser coined the 'frog riddle', which illustrates non-intuitive implications of conditional probabilities…
Magnetic moments in a helical edge can make weak correlations seem strong
Jukka I. Väyrynen, Florian Geissler, Leonid I. Glazman
We study the effect of localized magnetic moments on the conductance of a helical edge. Interaction with a local moment is an effective backscattering mechanism for the edge electr…
Evidence for broken Galilean invariance at the quantum spin Hall edge
Florian Geissler, François Crépin, Björn Trauzettel
We study transport properties of the helical edge channels of a quantum spin Hall (QSH) insulator, in the presence of electron-electron interactions and weak, local Rashba spin-orb…
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…
Group theoretical and topological analysis of the quantum spin Hall effect in silicene
Florian Geissler, Jan Carl Budich, Björn Trauzettel
Silicene consists of a monolayer of silicon atoms in a buckled honeycomb structure. It was recently discovered that the symmetry of such a system allows for interesting Rashba spin…
