We study the quantum phases of bosons with repulsive contact interactions on a two-leg
ladder in the presence of a uniform Abelian gauge field. The model realizes many …

The interplay between spontaneous symmetry breaking in many-body systems, the wavelike
nature of quantum particles and lattice effects produces an extraordinary behavior of the …

The joint action of a magnetic field and of interactions is crucial for the appearance of exotic
quantum phenomena, such as the quantum Hall effect. Owing to their rich nuclear structure …

Quantum gas systems are ideal analog quantum simulation platforms for tackling some of
the most challenging problems in strongly correlated quantum matter. However, they also …

This work explores the possibility of creating and controlling unconventional nonlinearities
by periodic driving, in a broad class of systems described by the nonlinear Schrödinger …

We study bosonic and fermionic quantum two-leg ladders with orbital magnetic flux. In such
systems, the ratio ν of particle density to magnetic flux shapes the phase space, as in …

The realization and detection of various phase transitions in interacting two-leg bosonic flux
ladders are at the frontier of the present theoretical and experimental research in condensed …

Flux ladders constitute the minimal setup enabling a systematic understanding of the rich
physics of interacting particles subjected simultaneously to strong magnetic fields and a …

We theoretically study the Hall effect on interacting M-leg ladder systems, comparing
different measures and properties of the zero temperature Hall response in the limit of weak …

The phase diagram of a half-filled hard-core boson two-leg ladder in a flux is investigated by
means of numerical simulations based on the density matrix renormalization group (DMRG) …
