Passage-time distributions from a spin-boson detector model
Gerhard C. Hegerfeldt, Jens Timo Neumann, Lawrence S. Schulman
The passage-time distribution for a spread-out quantum particle to traverse a specific region is calculated using a detailed quantum model for the detector involved. That model, de…
Investigation of a quantum mechanical detector model for moving, spread-out particles
Gerhard C. Hegerfeldt, Jens Timo Neumann, Lawrence S. Schulman
We investigate a fully quantum mechanical spin model for the detection of a moving particle. This model, developed in earlier work, is based on a collection of spins at fixed locat…
Scattering of two-level atoms by delta lasers: Exactly solvable models in atom optics
D. Seidel, J. G. Muga, G. C. Hegerfeldt
We study the scattering of two-level atoms at narrow laser fields, modeled by a -shape intensity profile. The unique properties of these potentials allow us to give simple analy…
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…
