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…

Analogue of cosmological particle creation in an ion trap
Ralf Schützhold, Michael Uhlmann, Lutz Petersen +3
We study phonons in a dynamical chain of ions confined by a trap with a time-dependent (axial) potential strength and demonstrate that they behave in the same way as quantum fields…
