Dissipative framework for subsystem dynamics of noninteracting quantum chains
Michele Coppola, Zala Lenarčič
When only local observables of a many-body quantum system are of interest, it is desirable to formulate a reduced description within the Hilbert space of the corresponding subsyste…
Limitations of the Markovian approximation in the harmonic oscillator
Michele Coppola, Zoubair Daouma, Malte Henkel
The quantum fluctuation-dissipation theorem is a central ingredient in the construction of quantum dynamics of Brownian motion which necessarily is non-Markovian. Yet, often Markov…
Learning the non-Markovian features of subsystem dynamics
Michele Coppola, Mari Carmen Bañuls, Zala LenarÄiÄ
The dynamics of local observables in a quantum many-body system can be formally described in the language of open systems. The problem is that the bath representing the complement…
Exact solution to a Bhatnagar-Gross-Krook-type equation for quantum lattice gases with dephasing noise
Michele Coppola
The mean-state dynamics of free fermions subject to random projective measurements of local occupation number operators is governed by a Lindblad equation with dephasing noise. In…
Measurments-induced quantum phase transitions
Dragi Karevski, Michele Coppola, Emanuele Tirrito +1
Dynamical phase transitions induced by local projective measurements have attracted a lot of attention in the past few years. It has been in particular argued that measurements may…
