Precursor of Laughlin state of hard core bosons on a two leg ladder
Alexandru Petrescu, Marie Piraud, Guillaume Roux +2
We study hard core bosons on a two leg ladder lattice under the orbital effect of a uniform magnetic field. At densities which are incommensurate with flux, the ground state is a M…
Chiral Mott Insulators, Meissner Effect, and Laughlin States in Quantum Ladders
Alexandru Petrescu, Karyn Le Hur
We introduce generic bosonic models exemplifying that chiral Meissner currents can persist in insulating phases of matter. We first consider interacting bosons on a two-leg ladder.…
Chiral Bosonic Phases on the Haldane Honeycomb Lattice
Ivana Vasic, Alexandru Petrescu, Karyn Le Hur +1
Recent experiments in ultracold atoms and photonic analogs have reported the implementation of artificial gauge fields in lattice systems, facilitating the realization of topologic…
Bosonic Mott Insulator with Meissner Currents
Alexandru Petrescu, Karyn Le Hur
We introduce a generic bosonic model exemplifying that (spin) Meissner currents can persist in insulating phases of matter. We consider two species of interacting bosons on a latti…
Anomalous Hall Effects of Light and Chiral Edge Modes on the Kagome Lattice
Alexandru Petrescu, Andrew A. Houck, Karyn Le Hur
We theoretically investigate a photonic Kagome lattice which can be realized in microwave cavity arrays using current technology. The Kagome lattice exhibits an exotic band structu…
