Supersolid and pair correlations of the extended Jaynes-Cummings-Hubbard model on triangular lattices
Lijuan Guo, Sebastian Greschner, Siyu Zhu +1
We study the extended Jaynes-Cummings-Hubbard model on triangular cavity lattices and zigzag ladders. By using density-matrix renormalization group methods, we observe various type…
Phases of Attractive Fermi Gases in Synthetic Dimensions
Sudeep Kumar Ghosh, Sebastian Greschner, Umesh K. Yadav +3
A novel way to produce quantum Hall ribbons in a cold atomic system is to use M hyperfine states of atoms in a 1D optical lattice to mimic an additional "synthetic dimension". A no…
Symmetry-broken states in a system of interacting bosons on a two-leg ladder with a uniform Abelian gauge field
S. Greschner, M. Piraud, F. Heidrich-Meisner +3
We study the quantum phases of bosons with repulsive contact interactions on a two-leg ladder in the presence of a uniform Abelian gauge field. The model realizes many interesting…
Ground State Properties of the One-Dimensional Unconstrained Pseudo-Anyon Hubbard Model
Wanzhou Zhang, Sebastian Greschner, Ernv Fan +2
We study the (pseudo-) anyon Hubbard model on a one-dimensional lattice without the presence of a three-body hardcore constraint. In particular, for the pseudo-fermion limit of a l…
Engineering interactions and anyon statistics by multicolor lattice-depth modulations
Lorenzo Cardarelli, Sebastian Greschner, Luis Santos
We show that a multicolor modulation of the depth of an optical lattice allows for a flexible independent control of correlated hopping, occupation-dependent gauge fields, effectiv…
