Implementation of STIRAP in degenerate systems by dimensionality reduction
G. Bevilacqua, G. Schaller, T. Brandes +1
We consider the problem of the implementation of Stimulated Raman Adiabatic Passage (STIRAP) processes in degenerate systems, with a view to be able to steer the system wave functi…
Vibrational mechanics in an optical lattice: controlling transport via potential renormalization
A. Wickenbrock, P. C. Holz, N. A. Abdul Wahab +3
We demonstrate theoretically and experimentally the phenomenon of vibrational resonance in a periodic potential, using cold atoms in an optical lattice as a model system. A high-fr…
Current reversals in a rocking ratchet: the frequency domain
A. Wickenbrock, D. Cubero, N. A. Abdul Wahab +2
Motivated by recent work [D. Cubero et al., Phys. Rev. E 82, 041116 (2010)], we examine the mechanisms which determine current reversals in rocking ratchets as observed by varying…
Two-dimensional rocking ratchet for cold atoms
V. Lebedev, F. Renzoni
We investigate experimentally a two-dimensional rocking ratchet for cold atoms, realized by using a driven three-beam dissipative optical lattice. AC forces are applied in perpendi…
Temperature and spatial diffusion of atoms cooled in a 3D linlin bright optical lattice
F. -R. Carminati, M. Schiavoni, L. Sanchez-Palencia +2
We present a detailed experimental study of a three-dimensional linlin bright optical lattice. Measurements of the atomic temperature and spatial diffusion coefficients are…
Slow light in three-level cold atoms: a numerical analysis
E. Cerboneschi, F. Renzoni, E. Arimondo
We investigate theoretically the slow group velocity of a pulse probe laser propagating through a cold sample and interacting with atoms in a three-level configuration having l…
