Preparation of atomic velocities by bound-state to resonance conversion
F. Delgado, A. Ruschhaupt, J. G. Muga
A procedure is proposed to control the average and width of the velocity distribution of ultra-cold atoms. The atoms are set initially in a bound state of an optical trap formed by…
Decay by tunneling of Bosonic and Fermionic Tonks-Girardeau Gases
A. del Campo, F. Delgado, G. Garcia-Calderon +2
We study the tunneling dynamics of bosonic and fermionic Tonks-Girardeau gases from a hard wall trap, in which one of the walls is substituted by a delta potential. Using the Fermi…
Suppression of Zeno effect for distant detectors
F. Delgado, J. G. Muga, G. Garcia-Calderon
We describe the influence of continuous measurement in a decaying system and the role of the distance from the detector to the initial location of the system. The detector is model…
The role of initial state reconstruction in short and long time deviations from exponential decay
J. G. Muga, F. Delgado, A. del Campo +1
We consider the role of the reconstruction of the initial state in the deviation from exponential decay at short and long times. The long time decay can be attributed to a wave tha…
Transition from discrete to continuous time of arrival distribution for a quantum particle
Eric A. Galapon, F. Delgado, J. Gonzalo Muga +1
We show that the Kijowski distribution for time of arrivals in the entire real line is the limiting distribution of the time of arrival distribution in a confining box as its lengt…
Velocity selection of ultra-cold atoms with Fabry-Perot laser devices: improvements and limits
A. Ruschhaupt, F. Delgado, J. G. Muga
We discuss a method to select the velocities of ultra-cold atoms with a modified Fabry-Perot type of device made of two effective barriers and a well created, respectively, by blue…
