Quantum model for double ionization of atoms in strong laser fields
Jakub S. Prauzner-Bechcicki, Krzysztof Sacha, Bruno Eckhardt +1
We discuss double ionization of atoms in strong laser pulses using a reduced dimensionality model. Following the insights obtained from an analysis of the classical mechanics of th…
Suppression of correlated electron escape in double ionization in strong laser fields
Bruno Eckhardt, Jakub S. Prauzner-Bechcicki, Krzysztof Sacha +1
The effect of the Pauli exclusion principle on double ionization of He atoms by strong, linearly polarized laser pulses is analyzed. We show that correlated electron escape, with e…
N-conserving Bogoliubov vacuum of a two component Bose-Einstein condensate: Density fluctuations close to a phase separation condition
Bartlomiej Oles, Krzysztof Sacha
Two-component Bose-Einstein condensates are considered within a number conserving version of the Bogoliubov theory. We show that the Bogoliubov vacuum state can be obtained in the…
