Quantum dwell times
J. A. Damborenea, I. L. Egusquiza, J. G. Muga +1
We put forward several inherently quantum characteristics of the dwell time, and propose an operational method to detect them. The quantum dwell time is pointed out to be a conserv…
Atomic time-of-arrival measurements with a laser of finite beam width
J. A. Damborenea, I. L. Egusquiza, G. C. Hegerfeldt +1
A natural approach to measure the time of arrival of an atom at a spatial region is to illuminate this region with a laser and detect the first fluorescence photons produced by the…
A measurement-based approach to quantum arrival times
J. A. Damborenea, I. L. Egusquiza, G. C. Hegerfeldt +1
For a quantum-mechanically spread-out particle we investigate a method for determining its arrival time at a specific location. The procedure is based on the emission of a first ph…
Bounds and enhancements for the Hartman effect
J. G. Muga, I. L. Egusquiza, J. A. Damborenea +1
The time of passage of the transmitted wave packet in a tunneling collision of a quantum particle with a square potential barrier becomes independent of the barrier width in a rang…
Asymptotic behaviour of the probability density in one dimension
J. A. Damborenea, I. L. Egusquiza, J. G. Muga
We demonstrate that the probability density of a quantum state moving freely in one dimension may decay faster than 1/t. Inverse quadratic and cubic dependences are illustrated wit…
Model for the arrival-time distribution in fluorescence time-of-flight experiments
J. G. Muga, A. D. Baute, J. A. Damborenea +1
An operational arrival-time distribution is defined as the distribution of detection times of the first photons emitted by two level atoms in resonance with a perpendicular laser b…
