Spontaneous time-reversal symmetry breaking for spinless fermions on a triangular lattice
Olivier Tieleman, Omjyoti Dutta, Maciej Lewenstein +1
As a minimal fermionic model with kinetic frustration, we study a system of spinless fermions in the lowest band of a triangular lattice with long-range repulsion. We find that the…
Quantum spin models with long-range interactions and tunnelings: A quantum Monte Carlo study
Michal Maik, Philipp Hauke, Omjyoti Dutta +2
We use a quantum Monte Carlo method to investigate various classes of 2D spin models with long-range interactions at low temperatures. In particular, we study a dipolar XXZ model w…
Orbital physics of polar Fermi molecules
O. Dutta, T. Sowiński, M. Lewenstein
We study a system of polar dipolar fermions in a two-dimensional optical lattice and show that multi-band Fermi-Hubbard model is necessary to discuss such system. By taking into ac…
