High-accuracy Complete Active Space multiconfiguration Dirac-Hartree-Fock calculations of hyperfine structure constants of the gold atom
Jacek Bierón, Charlotte Froese Fischer, Paul Indelicato +2
The multiconfiguration Dirac-Hartree-Fock (MCDHF) model has been employed to calculate the expectation values for the hyperfine splittings of the 5d96s2 2D3/2 and 5d96s2 2D5/2 leve…
Optimal geometry for efficient loading of an optical dipole trap
Andrzej Szczepkowicz, Leszek Krzemien, Adam Wojciechowski +6
One important factor which determines efficiency of loading cold atoms into an optical dipole trap from a magneto-optical trap is the distance between the trap centers. By studying…
Controlling atomic vapor density in paraffin-coated cells using light-induced atomic desorption
T. Karaulanov, M. T. Graf, D. English +10
Atomic-vapor density change due to light induced atomic desorption (LIAD) is studied in paraffin-coated rubidium, cesium, sodium and potassium cells. In the present experiment, low…
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…
Magnetometry Based on Nonlinear Magneto-Optical Rotation with Amplitude-Modulated Light
S. Pustelny, A. Wojciechowski, M. Gring +3
We report on an all-optical magnetometric technique based on nonlinear magneto-optical rotation with amplitude-modulated light. The method enables sensitive magnetic-field measurem…
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…
