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…

Quantum coherence and criticality in irreversible work
Adalberto D. Varizi, André P. Vieira, Cecilia Cormick +2
The irreversible work during a driving protocol constitutes one of the most widely studied measures in non-equilibrium thermodynamics, as it constitutes a proxy for entropy product…

Quantum Ising model in a period-2 modulated transverse field
Adalberto D. Varizi, Raphael C. Drumond
We study a finite spin- Ising chain with a spatially alternating transverse field of period 2. By means of a Jordan-Wigner transformation for even and odd sites, we ar…
