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…
