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…
Statistics of charge transfer in a tunnel junction coupled to an oscillator
J. Wabnig, D. V. Khomitsky, J. Rammer +1
The charge transfer statistics of a tunnel junction coupled to a quantum object is studied using the charge projection technique. The joint dynamics of the quantum object and the n…
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…
A network-based threshold model for the spreading of fads in society and markets
Andreas Gronlund, Petter Holme
We investigate the behavior of a threshold model for the spreading of fads and similar phenomena in society. The model is giving the fad dynamics and is intended to be confined to…
Searchability of Networks
M. Rosvall, A. Gronlund, P. Minnhagen +1
We investigate the searchability of complex systems in terms of their interconnectedness. Associating searchability with the number and size of branch points along the paths betwee…
