State space structure and entanglement of rotationally invariant spin systems
Heinz-Peter Breuer
We investigate the structure of SO(3)-invariant quantum systems which are composed of two particles with spins j_1 and j_2. The states of the composite spin system are represented…
Entanglement in SO(3)-invariant bipartite quantum systems
Heinz-Peter Breuer
The structure of the state spaces of bipartite (N tensor N) quantum systems which are invariant under product representations of the group SO(3) of three-dimensional proper rotatio…
Genuine quantum trajectories for non-Markovian processes
Heinz-Peter Breuer
A large class of non-Markovian quantum processes in open systems can be formulated through time-local master equations which are not in Lindblad form. It is shown that such process…
Non-Markovian dynamics in a spin star system: Exact solution and approximation techniques
Heinz-Peter Breuer, Daniel Burgarth, Francesco Petruccione
The reduced dynamics of a central spin coupled to a bath of N spin-1/2 particles arranged in a spin star configuration is investigated. The exact time evolution of the reduced dens…
The non-Markovian quantum behavior of open systems: An exact Monte Carlo method employing stochastic product states
Heinz-Peter Breuer
It is shown that the exact dynamics of a composite quantum system can be represented through a pair of product states which evolve according to a Markovian random jump process. Thi…
Exact quantum jump approach to open systems in Bosonic and spin baths
Heinz-Peter Breuer
A general method is developed which enables the exact treatment of the non-Markovian quantum dynamics of open systems through a Monte Carlo simulation technique. The method is base…
