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…
Resonance expansions in quantum mechanics
R. de la Madrid, G. Garcia-Calderon, J. G. Muga
The goal of this contribution is to discuss various resonance expansions that have been proposed in the literature.
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…
Tunneling dynamics in relativistic and nonrelativistic wave equations
F. Delgado, J. G. Muga, A. Ruschhaupt +2
We obtain the solution of a relativistic wave equation and compare it with the solution of the Schroedinger equation for a source with a sharp onset and excitation frequencies belo…
Equivalence between the real time Feynman histories and the quantum shutter approaches for the "passage time" in tunneling
Gaston Garcia-Calderon, Jorge Villavicencio, Norifumi Yamada
We show the equivalence of the functions and for the ``passage time'' in tunneling. The former, obtained within the framework of the real time Feynman h…
