Localized and extended states in a disordered trap
Luca Pezzé, Laurent Sanchez-Palencia
We study Anderson localization in a disordered potential combined with an inhomogeneous trap. We show that the spectrum displays both localized and extended states, which coexist a…
Macroscopic Superpositions of Phase States with Bose-Einstein Condensates
F. Piazza, L. Pezze', A. Smerzi
Quantum superpositions of macroscopically distinguishable states having distinct phases can be created with a Bose-Einstein condensate trapped in a periodic potential. The experime…
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…
