Hall effect in multi-leg bosonic ladders
Edmond Orignac, Roberta Citro, Thierry Giamarchi
We use bosonization to analyze the ground state Hall response of interacting bosonic N-leg ladders threaded by a flux. We derive an explicit expression of the Hall imbalance in a p…

One dimensional Bose-Hubbard model with long range hopping
Edmond Orignac
Interacting one-dimensional bosons with long range hopping decaying as a power law with distance are considered with the renormalization group and the self-consistent…
