Quantum back-reaction problems
Ralf Schützhold
The macroscopic behavior of many physical systems can be approximately described by classical quantities. However, quantum theory demands the existence of omnipresent quantum fluct…
Bogoliubov theory of quantum correlations in the time-dependent Bose-Hubbard model
Uwe R. Fischer, Ralf Schützhold, Michael Uhlmann
By means of an adapted mean-field expansion for large fillings , we study the evolution of quantum fluctuations in the time-dependent Bose-Hubbard model, starting in the sup…
Quantum toy model for black-hole back-reaction
Clovis Maia, Ralf Schützhold
We propose a simple quantum field theoretical toy model for black hole evaporation and study the back-reaction of Hawking radiation onto the classical background. It turns out that…
Decoherence in the dynamical quantum phase transition of the transverse Ising chain
Sarah Mostame, Gernot Schaller, Ralf Schützhold
For the prototypical example of the Ising chain in a transverse field, we study the impact of decoherence on the sweep through a second-order quantum phase transition. Apart from t…
