A perturbative approach to inelastic collisions in a Bose-Einstein Condensate
R. B. Mann, M. B. Young, I. Fuentes-Schuller
It has recently been discovered that for certain rates of mode-exchange collisions analytic solutions can be found for a Hamiltonian describing the two-mode Bose-Einstein condensat…

Adiabatic preparation without Quantum Phase Transitions
Gernot Schaller
Many physically interesting models show a quantum phase transition when a single parameter is varied through a critical point, where the ground state and the first excited state be…

Preservation of Positivity by Dynamical Coarse-Graining
Gernot Schaller, Tobias Brandes
We compare different quantum Master equations for the time evolution of the reduced density matrix. The widely applied secular approximation (rotating wave approximation) applied i…
