Finite-Temperature Renormalization Group Analysis of Interaction Effects in 2D Lattices of Bose-Einstein Condensates
A. Smerzi, P. Sodano, A. Trombettoni
By using a renormalization group analysis, we study the effect of interparticle interactions on the critical temperature at which the Berezinskii-Kosterlitz-Thouless (BKT) transiti…
Phase Sensitivity of a Mach-Zehnder Interferometer
Luca Pezze', Augusto Smerzi
The best performance of a Mach-Zehnder interferometer is achieved with the input state |N_T/2 + 1>|N_T/2-1 > + |N_T/2 - 1>|N_T/2+1>, being N_T the total number of atoms/photons. Th…
Beyond the Landau Criterion for Superfluidity
Sara Ianeselli, Chiara Menotti, Augusto Smerzi
According to the Landau criterion for superfluidity, a Bose-Einstein condensate flowing with a group velocity smaller than the sound velocity is energetically stable to the presenc…
Sub Shot-Noise Phase Sensitivity with a Bose-Einstein Condensate Mach-Zehnder Interferometer
L. Pezze', L. A. Collins A. Smerzi, G. P. Berman +1
Bose Einstein Condensates, with their coherence properties, have attracted wide interest for their possible application to ultra precise interferometry and ultra weak force sensors…
On Defect-Mediated Transitions in Bosonic Planar Lattices
A. Trombettoni, A. Smerzi, P. Sodano
We discuss the finite-temperature properties of Bose-Einstein condensates loaded on a 2D optical lattice. In an experimentally attainable range of parameters the system is describe…
