Quantum transients
A. del Campo, G. Garcia-Calderon, J. G. Muga
Quantum transients are temporary features of matter waves before they reach a stationary regime. Transients may arise after the preparation of an unstable initial state or due to a…
Relation between quantum dwell times and flux-flux correlations
J. Munoz, D. Seidel, J. G. Muga
We examine the connection between the dwell time of a quantum particle in a region of space and flux-flux correlations at the boundaries. It is shown that the first and second mome…
Momentum-space interferometry with trapped ultracold atoms
A. Ruschhaupt, A. del Campo, J. G. Muga
Quantum interferometers are generally set so that phase differences between paths in coordinate space combine constructive or destructively. Indeed, the interfering paths can also…
Avoided crossing resonances: structural and dynamical aspects
I. Lizuain, E. Hernandez-Concepcion, J. G. Muga
We examine structural and dynamical properties of quantum resonances associated with an avoided crossing and identify the parameter shifts where these properties attain maximal or…
Generalized relation between pulsed and continuous measurements in the quantum Zeno effect
J. G. Muga, J. Echanobe, A. del Campo +1
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…
Quantum motion effects in an ultracold-atom Mach-Zehnder interferometer
I. Lizuain, S. V. Mousavi, D. Seidel +1
We study the effect of quantum motion in a Mach-Zehnder interferometer where ultracold, two-level atoms cross a -- configuration of separated, laser illuminated regio…
