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…
Topological nature and the multiple Dirac cones hidden in Bismuth high-Tc superconductors
Gang Li, Binghai Yan, Ronny Thomale +1
Recent theoretical studies employing density-functional theory have predicted BaBiO (when doped with electrons) and YBiO to become a topological insulator (TI) with a l…
Numerical exploration of spontaneous broken symmetries in multi-orbital Hubbard models
Y. F. Kung, C. -C. Chen, B. Moritz +3
We study three proposals for broken symmetry in the cuprate pseudogap - oxygen antiferromagnetism, orbital loop currents, and circulating currents involving apex oxygens -…
Accessing topological superconductivity via a combined STM and renormalization group analysis
Lars Elster, Christian Platt, Ronny Thomale +2
The search for topological superconductors has recently become a key issue in condensed matter physics, because of their possible relevance to provide a platform for Majorana bound…
Generalized Kitaev Models and Slave Genons
Maissam Barkeshli, Hong-Chen Jiang, Ronny Thomale +1
We present a wide class of partially integrable lattice models with two-spin interactions, which generalize the Kitaev honeycomb model. These models have an infinite number of cons…
