Density-induced geometric frustration of ultra-cold bosons in optical lattices
Tapan Mishra, Sebastian Greschner, Luis Santos
A density-dependent gauge field may induce density-induced geometric frustration, leading to a non-trivial interplay between density modulation and frustration, which we illustrate…
Frustration-induced supersolids in the absence of inter-site interactions
Tapan Mishra, Sebastian Greschner, Luis Santos
We discuss a mechanism for the realization of supersolids in lattices in the absence of intersite interactions that surprisingly works as well at unit filling. This mechanism, that…
Density-dependent synthetic magnetism for ultracold atoms in optical lattices
Sebastian Greschner, Daniel Huerga, Gaoyong Sun +2
Raman-assisted hopping can allow for the creation of density-dependent synthetic magnetism for cold neutral gases in optical lattices. We show that the density-dependent fields lea…
The Anyon Hubbard Model in One-Dimensional Optical Lattices
Sebastian Greschner, Luis Santos
Raman-assisted hopping may be used to realize the anyon Hubbard model in one-dimensional optical lattices. We propose a feasible scenario that significantly improves the proposal o…
