Effect of transverse confinement on a quasi-one dimensional dipolar Bose gas
Stefania De Palo, Edmond Orignac, Roberta Citro +1
We study a gas of bosonic dipolar atoms in the presence of a transverse harmonic trapping potential by using an improved variational Bethe ansatz, which includes the transverse wid…
Polarization angle dependence of the breathing modes in confined one-dimensional dipolar bosons
S. De Palo, E. Orignac, M. L. Chiofalo +1
Probing the radial collective oscillation of a trapped quantum system is an accurate experimental tool to investigate interactions and dimensionality effects. We consider a fully p…
Variational Bethe Ansatz approach for dipolar one-dimensional bosons
S. De Palo, R. Citro, E. Orignac
We propose a variational approximation to the ground state energy of a one-dimensional gas of interacting bosons on the continuum based on the Bethe Ansatz ground state wavefunctio…
Quantum phase transitions of a two-leg bosonic ladder in an artificial gauge field
R. Citro, S. De Palo, M. Di Dio +1
We consider a two leg bosonic ladder in a gauge field with both interleg hopping and interleg repulsion. As a function of the flux, the interleg interaction converts the com…
Vortex lattice melting in a boson-ladder in artificial gauge field
E. Orignac, R. Citro, M. Di Dio +1
We consider a two-leg boson ladder in an artificial U(1) gauge field and show that, in the presence of interleg attractive interaction, the flux induced Vortex state can be melted…
Incommensurate phases of a bosonic two-leg ladder under a flux
Edmond Orignac, Roberta Citro, Mario Di Dio +2
A boson two--leg ladder in the presence of a synthetic magnetic flux is investigated by means of bosonization techniques and Density Matrix Renormalization Group (DMRG). We follow…
