Creating Ground State Molecules with Optical Feshbach Resonances in Tight Traps
Christiane P. Koch Françoise Masnou-Seeuws Ronnie Kosloff
We propose to create ultracold ground state molecules in an atomic Bose-Einstein condensate by adiabatic crossing of an optical Feshbach resonance. We envision a scheme where the l…
Coherence protection by the quantum Zeno effect and non-holonomic control in a Rydberg Rubidium isotope
E. Brion, V. M. Akulin, D. Comparat +6
The protection of the coherence of open quantum systems against the influence of their environment is a very topical issue. A scheme is proposed here which protects a general quant…
Dissipative quantum dynamics with the Surrogate Hamiltonian approach. A comparison between spin and harmonic baths
D. Gelman, C. P. Koch, R. Kosloff
The dissipative quantum dynamics of an anharmonic oscillator coupled to a bath is studied with the purpose of elucidating the differences between the relaxation to a spin bath and…
Stabilization of Ultracold Molecules Using Optimal Control Theory
Christiane P. Koch, José P. Palao, Ronnie Kosloff +1
In recent experiments on ultracold matter, molecules have been produced from ultracold atoms by photoassociation, Feshbach resonances, and three-body recombination. The created mol…
Ionization of Rydberg atoms embedded in an ultracold plasma
Nicolas Vanhaecke, Daniel Comparat, Duncan A. Tate +1
We have studied the behavior of cold Rydberg atoms embedded in an ultracold plasma. We demonstrate that even deeply bound Rydberg atoms are completely ionized in such an environmen…
