How to measure the wave-function absolute squared of a moving particle by using mirrors
Volker Hannstein, Gerhard C. Hegerfeldt
We consider a slow particle with wave function , moving freely in some direction. A mirror is briefly switched on around a time and its position is scanned. It is…
Simplified approach to double jumps for fluorescing dipole-dipole interacting atoms
Volker Hannstein, Gerhard C. Hegerfeldt
A simplified scheme for the investigation of cooperative effects in the quantum jump statistics of small numbers of fluorescing atoms and ions in a trap is presented. It allows the…
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…
Cooperative quantum jumps for three dipole-interacting atoms
Volker Hannstein, Gerhard C. Hegerfeldt
We investigate the effect of the dipole-dipole interaction on the quantum jump statistics of three atoms. This is done for three-level systems in a V configuration and in what may…
Cooperative fluorescence effects for dipole-dipole interacting systems with experimentally relevant level configurations
Volker Hannstein, Gerhard C. Hegerfeldt
The mutual dipole-dipole interaction of atoms in a trap can affect their fluorescence. Extremely large effects were reported for double jumps between different intensity periods in…
