Structural and dynamical aspects of avoided-crossing resonances in a $3$-level $\Lambda$ system

Autor: Lizuain, I., Echanobe, J., Ruschhaupt, A., Muga, J. G., Steck, D. A.

Publikováno v: Phys. Rev. A 82, 065602 (2010)

In a recent publication [Phys. Rev. A 79, 065602 (2009)] it was shown that an avoided-crossing resonance can be defined in different ways, according to level-structural or dynamical aspects, which do not coincide in general. Here a simple $3$-level s

Cold atom dynamics in crossed laser beam waveguides

Autor: Torrontegui, E., Echanobe, J., Ruschhaupt, A., Guéry-Odelin, D., Muga, J. G.

Publikováno v: Phys Rev A (2010)

We study the dynamics of neutral cold atoms in an $L$-shaped crossed-beam optical waveguide formed by two perpendicular red-detuned lasers of different intensities and a blue-detuned laser at the corner. Complemented with a vibrational cooling proces

Generalized relation between pulsed and continuous measurements in the quantum Zeno effect

Autor: Muga, J. G., Echanobe, J., del Campo, A., Lizuain, I.

Publikováno v: J. Phys. B: At. Mol. Opt. Phys. 41, 175501 (2008)

A relation is found between pulsed measurements of the excited state probability of a two-level atom illuminated by a driving laser, and a continuous measurement by a second laser coupling the excited state to a third state which decays rapidly and i

Report

Disclosing hidden information in the quantum Zeno effect: Pulsed measurement of the quantum time of arrival

Autor: Echanobe, J., del Campo, A., Muga, J. G.

Publikováno v: Phys. Rev. A 77, 032112 (2008)

Repeated measurements of a quantum particle to check its presence in a region of space was proposed long ago [G. R. Allcock, Ann. Phys. {\bf 53}, 286 (1969)] as a natural way to determine the distribution of times of arrival at the orthogonal subspac
