Density-Dependent Synthetic Gauge Fields Using Periodically Modulated Interactions
S. Greschner, G. Sun, D. Poletti +1
We show that density-dependent synthetic gauge fields may be engineered by combining periodically modu- lated interactions and Raman-assisted hopping in spin-dependent optical latt…

Dirac fields in curved spacetime as Fermi-Hubbard model with non unitary tunnelings
Jiří Minář, Benoît Grémaud
In this article we show that a Dirac Hamiltonian in a curved background spacetime can be interpreted, when discretized, as a tight binding Fermi-Hubbard model with non unitary tunn…
