On the exact renormalization of states in quantum field theories
… by a non-unitary quantum channels generated by a Lindbladian which we derive. We solve the resulting Lindblad equation for Gaussian density matrices and compute the flow equation to second order in perturbation theory for a φ4 self interaction. We also calculate channel monotones such as the …

Analytical and Numerical Study of Lindblad Equations
<p>Lindblad equations, since introduced in 1976 by Lindblad, and by Gorini, Kossakowski, and Sudarshan, have received much attention in many areas of scientific research. Around the past fifty years, many properties and structures of Lindblad equations have been discovered and identified. In this …

Dinamica effettiva di sistemi quantistici driven chiusi e aperti
… which expresses the solution of a differential equation into an exponential form. The result of the technique is a coarse-grained effective Hamiltonian valid at low energies which is able to average out the fast dynamics and to capture the degrees of freedom which are more relevant for the …

Many-body entangled dynamics of closed and open systems for quantum simulators
… We focus on large reservoirs described by the Lindblad master equation. The research questions revolve around the thermalization of a many-body quantum system. This study treating open quantum systems can be seen as the analog of the eigenstate thermalization hypothesis vs. generalized Gibbs …
