Dynamical phase transitions in dissipative quantum dynamics with quantum optical realization
Valentin Link, Walter T. Strunz
We study dynamical phase transitions (DPT) in the driven and damped Dicke model, realizable for example by a driven atomic ensemble collectively coupled to a damped cavity mode. Th…
Revealing the nature of non-equilibrium phase transitions with quantum trajectories
Valentin Link, Kimmo Luoma, Walter T. Strunz
A damped and driven collective spin system is analyzed by using quantum state diffusion. This approach allows for a mostly analytical treatment of the investigated non-equilibrium…
Stochastic Feshbach Projection for the Dynamics of Open Quantum Systems
Valentin Link, Walter T. Strunz
We present a stochastic projection formalism for the description of quantum dynamics in Bosonic or spin environments. The Schrödinger equation in coherent state representation with…
Geometry of Gaussian quantum states
Valentin Link, Walter T. Strunz
We study the Hilbert-Schmidt measure on the manifold of mixed Gaussian states in multi mode continuous variable quantum systems. An analytical expression for the Hilbert-Schmidt vo…
