Landau levels of Majorana fermions in a spin liquid
Stephan Rachel, Lars Fritz, Matthias Vojta
Majorana fermions were originally proposed as elementary particles acting as their own antiparticles. In recent years, it has become clear that Majorana fermions can instead be rea…
Phase Diagram and Quantum Order by Disorder in the Kitaev - Honeycomb Magnet
Ioannis Rousochatzakis, Johannes Reuther, Ronny Thomale +2
We show that the topological Kitaev spin liquid on the honeycomb lattice is extremely fragile against the second-neighbor Kitaev coupling , which has recently been shown to be…
Quantum disordered insulating phase in the frustrated cubic-lattice Hubbard model
Manuel Laubach, Darshan G. Joshi, Johannes Reuther +3
In the quest for quantum spin liquids in three spatial dimensions (3D), we study the half-filled Hubbard model on the simple cubic lattice with hopping processes up to third neighb…
Spin texture of generic helical edge states
Alexia Rod, Thomas L. Schmidt, Stephan Rachel
We study the spin texture of a generic helical liquid, the edge modes of a two-dimensional topological insulator with broken axial spin-symmetry. By considering honeycomb and squar…
Entanglement analysis of isotropic spin-1 chains
Ronny Thomale, Stephan Rachel, B. Andrei Bernevig +1
We investigate entanglement spectra of the SO(3) bilinear-biquadratic spin-1 chain, a model with phases exhibiting spontaneous symmetry breaking (both translation and spin rotation…
