Controlling double ionization of atoms in intense bichromatic laser pulses
ionization atoms intense bichromatic laser pulses
2010/11/17
We consider the classical dynamics of a two-electron system subjected to an intense bichromatic linearly polarized laser pulse. By varying the parameters of the field, such as the phase lag and the r...
Ultracold Atoms as a Target: Absolute Scattering Cross-Section Measurements
Ultracold Atoms Target Scattering Cross-Section Measurements
2010/11/12
We report on a new experimental platform for the measurement of absolute scattering cross-sections. The target atoms are trapped in an optical dipole trap and are exposed to an incident particle beam...
Vacancy decay in endohedral atoms: the role of non-central position of the atom
endohedral atoms non-central position of the atom
2010/11/16
We demonstrate that the Auger decay rate in an endohedral atom is very sensitive to the atom's location in the fullerene cage. Two additional decay channels appear in an endohedral system: (a) the cha...
A Moving Magnetic Trap Decelerator: a New Source for Cold Atoms and Molecules
Moving Magnetic Trap Decelerator Source Cold Atoms Molecules
2010/11/12
We present a new source of cold paramagnetic atoms and molecules. The paramagnetic particles are cooled during the adiabatic expansion and become entrained in an intense, cold but fast supersonic bea...
Dirac Equation For Cold Atoms In Artificial Curved Spacetimes
Dirac Equation Cold Atoms Artificial Curved Spacetimes
2010/11/11
We argue that the Fermi-Hubbard Hamiltonian describing the physics of ultracold atoms on optical lattices in the presence of artificial non-Abelian gauge fields, is exactly equivalent to the gauge the...

Spin-squeezed atoms interferometry atomic clocks
2010/4/15
Physicists in Germany are the first to use "spin-squeezed" atoms to boost the precision of an interferometer based on interacting atoms. Their work involves entangling several hundred atoms in a way t...
Autoionization of He atoms induced by partially stripped ion impact
autoionization post-collisional interactions rainbow scattering
2010/6/30
A study of the autoionization process induced by partially stripped ion impact is performed. The Barrachina-Macek model is extended to the case in which the projectile-emitted electron interaction is ...
Spin dynamics of wave packets evolving with the Dirac Hamiltonian in atoms with high Z
Spin dynamics wave packets evolving Dirac Hamiltonian atoms high Z
2010/10/15
The motion of circular WP for one electron in central Coulomb field with high Z is calculated. The WP is defined in terms of solutions of the Dirac equation in order to take into account all possible ...
