Rashba spin orbit coupling in the Kane-Mele-Hubbard model
Manuel Laubach, Johannes Reuther, Ronny Thomale +1
Spin-orbit (SO) coupling is the crucial parameter to drive topological insulating phases in electronic band models. In particular, the generic emergence of SO coupling involves the…
Cluster Functional Renormalization Group
Johannes Reuther, Ronny Thomale
Functional renormalization group (FRG) has become a diverse and powerful tool to derive effective low-energy scattering vertices of interacting many-body systems. Starting from a n…
Gate defined wires in HgTe quantum wells: from Majorana fermions to spintronics
Johannes Reuther, Jason Alicea, Amir Yacoby
We introduce a promising new platform for Majorana zero-modes and various spintronics applications based on gate-defined wires in HgTe quantum wells. Due to the Dirac-like band str…
Renormalization group analysis of competing quantum phases in the J1-J2 Heisenberg model on the kagome lattice
Raik Suttner, Christian Platt, Johannes Reuther +1
Recent discoveries in neutron scattering experiments for Kapellasite and Herbertsmithite as well as theoretical calculations of possible spin liquid phases have revived interest in…
