Laughlin-like states in bosonic and fermionic synthetic ladders — •Marcello Calvanese Strinati — NEST, Scuola Normale Superiore and Istituto Nanoscienze-CNR, I-56126 Pisa, Italy

We present a numerical study of one-dimensional Laughlin-like states in bosonic and fermionic ladders, which can be realized in one-dimensional gases with synthetic dimension. Similar to two-dimensional genuine Laughlin states, our system exhibits counter-propagating fractional modes. Laughlin-like states in our systems are identified by specific signatures in the chiral current and entanglement properties. We corroborate our numerical results with an analytical analysis based on bosonization techniques.
