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…

Linear stochastic wave-equations for continuously measured quantum systems
Peter Goetsch, Robert Graham
While the linearity of the Schrödinger equation and the superposition principle are fundamental to quantum mechanics, so are the backaction of measurements and the resulting nonlin…
