Systematic Perturbation Theory for Dynamical Coarse-Graining
Gernot Schaller, Philipp Zedler, Tobias Brandes
We demonstrate how the dynamical coarse-graining approach can be systematically extended to higher orders in the coupling between system and reservoir. Up to second order in the co…
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…
Matter Coupling to Strong Electromagnetic Fields in Two-Level Quantum Systems with Broken Inversion Symmetry
O. V. Kibis, G. Ya. Slepyan, S. A. Maksimenko +1
We demonstrate theoretically the parametric oscillator behavior of a two-level quantum system with broken inversion symmetry exposed to a strong electromagnetic field. A multitude…
Convex Trace Functions on Quantum Channels and the Additivity Conjecture
Markus Mueller
We study a natural generalization of the additivity problem in quantum information theory: given a pair of quantum channels, then what is the set of convex trace functions that att…
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…
