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…

Platforms for the realization and characterization of Tomonaga-Luttinger liquids
Isabelle Bouchoule, Roberta Citro, Tim Duty +5
The concept of a Tomonaga-Luttinger liquid (TLL) has been established as a fundamental theory for the understanding of one-dimensional quantum systems. Originally formulated as a r…

Hall response in interacting bosonic and fermionic ladders
R. Citro, T. Giamarchi, E. Orignac
We use bosonization, retaining band curvature terms, to analyze the Hall response of interacting bosonic and fermionic two-leg ladders threaded by a flux. We derive an explicit exp…
