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…
Fluctuations and Entanglement spectrum in quantum Hall states
Alexandru Petrescu, H. Francis Song, Stephan Rachel +6
The measurement of quantum entanglement in many-body systems remains challenging. One experimentally relevant fact about quantum entanglement is that in systems whose degrees of fr…
