Optimal molecular alignment and orientation through rotational ladder climbing
Julien Salomon, Claude M. Dion, Gabriel Turinici
We study the control by electromagnetic fields of molecular alignment and orientation, in a linear, rigid rotor model. With the help of a monotonically convergent algorithm, we fin…
Time dependence of laser cooling in optical lattices
Claude M. Dion, Peder Sjolund, Stefan J. H. Petra +2
We study the dynamics of the cooling of a gas of caesium atoms in an optical lattice, both experimentally and with 1D full-quantum Monte Carlo simulations. We find that, contrary t…
Optimally Controlled Field-Free Orientation of the Kicked Molecule
Claude M. Dion, Arne Keller, Osman Atabek
Efficient and long-lived field-free molecular orientation is achieved using only two kicks appropriately delayed in time. The understanding of the mechanism rests upon a molecular…
Reaching optimally oriented molecular states by laser kicks
D. Sugny, A. Keller, O. Atabek +4
We present a strategy for post-pulse orientation aiming both at efficiency and maximal duration within a rotational period. We first identify the optimally oriented states which fu…
Molecular Alignment and Orientation: From Laser-Induced Mechanisms to Optimal Control
O. Atabek, C. M. Dion
Genetic algorithms, as implemented in optimal control strategies, are currently successfully exploited in a wide range of problems in molecular physics. In this context, laser cont…
Spectral method for the time-dependent Gross-Pitaevskii equation with a harmonic trap
Claude M. Dion, Eric Cances
We study the numerical resolution of the time-dependent Gross-Pitaevskii equation, a non-linear Schroedinger equation used to simulate the dynamics of Bose-Einstein condensates. Co…
