Transient effects and reconstruction of the energy spectra in the time evolution of transmitted Gaussian wave packets
Sergio Cordero, Gaston Garcia-Calderon
We derive an exact analytical solution to the time-dependent Schrödinger equation for transmission of a Gaussian wave packet through an arbitrary potential of finite range. We cons…
Invisibility of quantum systems to tunneling of matter waves
Sergio Cordero, Gaston Garcia-Calderon
We show that an appropriate choice of the potential parameters in one-dimensional quantum systems allows for unity transmission of the tunneling particle at all incident tunneling…
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…
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…
Full time nonexponential decay in double-barrier quantum structures
Gaston Garcia-Calderon, Jorge Villavicencio
We examine an analytical expression for the survival probability for the time evolution of quantum decay to discuss a regime where quantum decay is nonexponential at all times. We…
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…
