Single atom edge-like states via quantum interference
G. Pelegrí, J. Polo, A. Turpin +3
We demonstrate how quantum interference may lead to the appearance of robust edge-like states of a single ultracold atom in a two-dimensional optical ribbon. We show that these sta…
Emergent non-trivial lattices for topological insulators
O. Dutta, A. Przysiezna, M. Lewenstein
Materials with non-trivial lattice geometries allow for the creation of exotic states of matter like topologically insulating states. Therefore searching for such materials is an i…
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…
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…
Strongly correlated states of a small cold atomic cloud from geometric gauge fields
B. Juliá-Díaz, D. Dagnino, K. J. Günter +4
Using exact diagonalization for a small system of cold bosonic atoms, we analyze the emergence of strongly correlated states in the presence of an artificial magnetic field. This g…
Two component Bose-Hubbard model with higher angular momentum states
J. Pietraszewicz, T. Sowinski, M. Brewczyk +3
We study a Bose-Hubbard Hamiltonian of ultracold two component gas of spinor Chromium atoms. Dipolar interactions of magnetic moments while tuned resonantly by ultralow magnetic fi…
