Resonant tunneling of Bose-Einstein condensates in optical lattices
Alessandro Zenesini, Carlo Sias, Hans Lignier +7
In this article, we present theoretical as well as experimental results on resonantly enhanced tunneling of Bose-Einstein condensates in optical lattices both in the linear case an…
Resonantly enhanced tunneling of Bose-Einstein condensates in periodic potentials
C. Sias, A. Zenesini, H. Lignier +4
We report on measurements of resonantly enhanced tunneling of Bose-Einstein condensates loaded into an optical lattice. By controlling the initial conditions of our system we were…
Mechanism and Lineshapes of Sub-Fourier Resonances
Hans Lignier, Jean Claude Garreau, Pascal Szriftgiser +1
Subtle internal interference effects allow quantum-chaotic systems to display "sub-Fourier" resonances, i.e. to distinguish two neighboring driving frequencies in a time shorter th…
