Correlation-driven charge order in a frustrated two-dimensional atom lattice
Florian Adler, Stephan Rachel, Manuel Laubach +4
We thoroughly examine the ground state of the triangular lattice of Pb on Si(111) using scanning tunneling microscopy. We detect charge-order, accompanied by a subtle structural re…
Three-band Hubbard model for NaIrO: Topological insulator, zigzag antiferromagnet, and Kitaev-Heisenberg material
Manuel Laubach, Johannes Reuther, Ronny Thomale +1
NaIrO was one of the first materials proposed to feature the Kane-Mele type topological insulator phase. Contemporaneously it was claimed that the very same material is in…
Density wave instabilities and surface state evolution in interacting Weyl semimetals
Manuel Laubach, Christian Platt, Ronny Thomale +2
We investigate the interplay of many-body and band structure effects of interacting Weyl semimetals (WSM). Attractive and repulsive Hubbard interactions are studied within a model…
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…
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…
Phase diagram of the Hubbard model on the anisotropic triangular lattice
Manuel Laubach, Ronny Thomale, Christian Platt +2
We investigate the Hubbard model on the anisotropic triangular lattice as a suggested effective description of the Mott phase in various triangular organic compounds. Employing the…
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…
Fluctuation-induced Topological Quantum Phase Transitions in Quantum Spin Hall and Quantum Anomalous Hall Insulators
Jan Carl Budich, Ronny Thomale, Gang Li +2
We investigate the role of quantum fluctuations in topological quantum phase transitions of quantum spin Hall insulators and quantum anomalous Hall insulators. Employing the variat…
