Quantum simulation of conductivity plateaux and fractional quantum Hall effect using ultracold atoms
Nuria Barberán, Daniel Dagnino, Miguel Angel García-March +3
We analyze the role of impurities in the fractional quantum Hall effect using a highly controllable system of ultracold atoms. We investigate the mechanism responsible for the form…
Strongly correlated states of a small cold atomic cloud from geometric gauge fields
B. Juliá-Díaz, D. Dagnino, K. J. Günter +4
Using exact diagonalization for a small system of cold bosonic atoms, we analyze the emergence of strongly correlated states in the presence of an artificial magnetic field. This g…
Macroscopic self trapping in BECs: analysis of a dynamical quantum phase transition
B. Julia-Diaz, D. Dagnino, M. Lewenstein +2
We consider a Bose-Einstein condensate in a double-well potential undergoing a dynamical transition from the regime of Josephson oscillations to the regime of self-trapping. We ana…
Vortex nucleation in mesoscopic Bose superfluid and breaking of the parity symmetry
D. Dagnino, N. Barberán, M. Lewenstein
We analyze vortex nucleation in mezoscopic 2D Bose superfluid in a rotating trap. We explicitly include a weakly anisotropic stirring potential, breaking thus explicitly the axial…
Vortex nucleation as a case study of symmetry breaking in quantum systems
D. Dagnino, N. Barberan, M. Lewenstein +1
Mean-field methods are a very powerful tool for investigating weakly interacting many-body systems in many branches of physics. In particular, they describe with excellent accuracy…
Symmetry breaking in small rotating cloud of trapped ultracold Bose atoms
D. Dagnino, N. Barberán, M. Lewenstein +2
We study the signatures of rotational and phase symmetry breaking in small rotating clouds of trapped ultracold Bose atoms by looking at rigorously defined condensate wave function…
