Interacting surface states of three-dimensional topological insulators
T. Neupert, S. Rachel, R. Thomale +1
We numerically investigate the surface states of a strong topological insulator in the presence of strong electron-electron interactions. We choose a spherical topological insulato…
Quantum paramagnet in a flux triangular lattice Hubbard model
Stephan Rachel, Manuel Laubach, Johannes Reuther +1
We propose the flux triangular lattice Hubbard model (-THM) as a prototypical setup to stabilize magnetically disordered quantum states of matter in the presence of charge f…
Spin-resolved entanglement spectroscopy of critical spin chains and Luttinger liquids
Nicolas Laflorencie, Stephan Rachel
Quantum critical chains are well described and understood by virtue of conformal field theory. Still the meaning of the real space entanglement spectrum -- the eigenvalues of the r…
Dimensional crossover and cold-atom realization of topological Mott insulators
Mathias S. Scheurer, Stephan Rachel, Peter P. Orth
We propose a cold-atom setup which allows for a dimensional crossover from a two-dimensional quantum spin Hall insulating phase to a three-dimensional strong topological insulator…
Fluctuations and Entanglement spectrum in quantum Hall states
Alexandru Petrescu, H. Francis Song, Stephan Rachel +6
The measurement of quantum entanglement in many-body systems remains challenging. One experimentally relevant fact about quantum entanglement is that in systems whose degrees of fr…
Spiral order in the honeycomb iridate Li2IrO3
Johannes Reuther, Ronny Thomale, Stephan Rachel
The honeycomb iridates A2IrO3 (A=Na, Li) constitute promising candidate materials to realize the Heisenberg-Kitaev model (HKM) in nature, hosting unconventional magnetic as well as…
