Wave Function Renormalization Effects in Resonantly Enhanced Tunneling
N. Lörch, F. V. Pepe, H. Lignier +8
We study the time evolution of ultra-cold atoms in an accelerated optical lattice. For a Bose- Einstein condensate with a narrow quasi-momentum distribution in a shallow optical la…
Time-resolved measurement of Landau--Zener tunneling in different bases
G. Tayebirad, A. Zenesini, D. Ciampini +5
A comprehensive study of the tunneling dynamics of a Bose--Einstein condensate in a tilted periodic potential is presented. We report numerical and experimental results on time-res…
Stochastic webs and quantum transport in superlattices: an introductory review
S. M. Soskin, P. V. E. McClintock, T. M. Fromhold +2
Stochastic webs were discovered, first by Arnold for multi-dimensional Hamiltonian systems, and later by Chernikov et al. for the low-dimensional case. Generated by weak perturbati…
Atomic micromotion and geometric forces in a triaxial magnetic trap
J. H. Müller, O. Morsch, D. Ciampini +3
Non-adiabatic motion of Bose-Einstein condensates of rubidium atoms arising from the dynamical nature of a time-orbiting-potential (TOP) trap was observed experimentally. The orbit…
Oscillation Frequencies for a Bose Condensate in a Triaxial Magnetic Trap
E. Cerboneschi, R. Mannella, E. Arimondo +1
We investigate the dynamics of a Bose condensate, interacting with either repulsive or attractive forces, confined in a fully anisotropic harmonic potential. The (3+1)-dimensional…
