Shortcuts to adiabaticity
E. Torrontegui, S. Ibáñez, S. Martínez-Garaot +6
Quantum adiabatic processes -that keep constant the populations in the instantaneous eigenbasis of a time-dependent Hamiltonian- are very useful to prepare and manipulate states, b…
Matter wave scattering on an amplitude-modulated optical lattice
Pierrick Cheiney, Charlotte Fabre, François Vermersch +4
We experimentally study the scattering of guided matter waves on an amplitude-modulated optical lattice. We observe different types of frequency-dependent dips in the asymptotic ou…
Optically guided beam splitter for propagating matter waves
Giovanni Luca Gattobigio, Antoine Couvert, Gael Reinaudi +2
We study experimentally and theoretically a beam splitter setup for guided atomic matter waves. The matter wave is a guided atom laser that can be tuned from quasi-monomode to a re…
