Contributions from populations and coherences in non-equilibrium entropy production
Adalberto D. Varizi, Mariana A. Cipolla, Martí Perarnau-Llobet +2
The entropy produced when a quantum system is driven away from equilibrium can be decomposed in two parts, one related with populations and the other with quantum coherences. The l…

Exact open dynamics of a generalized class of dephasing-type spin-boson models
Mariana Afeche Cipolla, Gabriel T. Landi
We discuss a generalization of the dephasing-type spin-boson model in which N qubits are connected to K bosonic modes in an arbitrary way. The model can be solved exactly for any i…
