Shifts and widths of collective excitations in trapped Bose gases by the dielectric formalism
J. Reidl, A. Csordás, R. Graham +1
We present predictions for the temperature dependent shifts and damping rates. They are obtained by applying the dielectric formalism to a simple model of a trapped Bose gas. Withi…

Cat States and Single Runs for the Damped Harmonic Oscillator
Peter Goetsch, Robert Graham, Fritz Haake
We discuss the fate of initial states of the cat type for the damped harmonic oscillator, mostly employing a linear version of the stochastic Schrödinger equation. We also comment…
