Lattice symmetry and emergence of antiferromagnetic quantum Hall states
Morad Ebrahimkhas, Mohsen Hafez-Torbati, Walter Hofstetter
Strong local interaction in systems with non-trivial topological bands can stabilize quantum states such as magnetic topological insulators. We investigate the influence of the lat…
Interaction-driven topological phase transitions in fermionic SU() systems
Mohsen Hafez-Torbati, Jun-Hui Zheng, Bernhard Irsigler +1
We consider SU() fermions on the triangular lattice in the presence of a gauge potential which stabilizes a quantum Hall insulator (QHI) at the density of one particle per latti…
Competing Charge and Magnetic Order in Fermionic Multi-Component Systems
Mohsen Hafez-Torbati, Walter Hofstetter
We consider the fermionic SU() Hubbard model on the triangular lattice in the presence of a three-sublattice staggered potential which provides the possibility to investigate th…
Spin-imbalance-induced transverse magnetization in the Hofstadter-Hubbard model
Bernhard Irsigler, Jun-Hui Zheng, Mohsen Hafez-Torbati +1
The fermionic, time-reversal invariant Hofstadter-Hubbard model with a population difference between the two spin states is investigated. In the strongly interacting regime, where…
Density-wave steady-state phase of dissipative ultracold fermions with nearest-neighbor interactions
Jaromir Panas, Michael Pasek, Arya Dhar +6
In this work we investigate the effect of local dissipation on the presence of density-wave ordering in spinful fermions with both local and nearest-neighbor interactions as descri…
Artificial Spin-Orbit Coupling and Exotic Mott Insulators
Mohsen Hafez-Torbati, Walter Hofstetter
Motivated by recent progress in the realization of artificial gauge fields and Mott insulators using alkaline-earth-like atoms in optical lattices, we develop an unbiased $…
