Quantum optical time-of-arrival model in three dimensions
V. Hannstein, G. C. Hegerfeldt, J. G. Muga
We investigate the three-dimensional formulation of a recently proposed operational arrival-time model. It is shown that within typical conditions for optical transitions the resul…
An atom diode
A. Ruschhaupt, J. G. Muga
An atom diode, i.e., a device that lets the ground state atom pass in one direction but not in the opposite direction in a velocity range is devised. It is based on the adiabatic t…
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…
Simultaneous arrival of information in absorbing wave guides
A. Ruschhaupt, J. G. Muga
We demonstrate that the temporal peak generated by specific electromagnetic pulses may arrive at different positions simultaneously in an absorbing wave guide. The effect can be us…
