Work and efficiency fluctuations in a quantum Otto cycle with idle levels
Maron F. Anka, Thiago R. de Oliveira, Daniel Jonathan
We study the performance of a quantum Otto heat engine with two spins coupled by a Heisenberg interaction, taking into account not only the mean values of work and efficiency but a…

Smooth Crossover Between Weak and Strong Thermalization using Rigorous Bounds on Equilibration of Isolated Systems
Luis Fernando dos Prazeres, Thiago R. de Oliveira
It is usually expected and observed that non-integrable isolated quantum systems thermalize. However, for some non-integrable spin chain models, in a numerical study, initial state…

Canonical typicality under general quantum channels
Pedro S. Correia, Gabriel Dias Carvalho, Thiago R. de Oliveira +2
With the control of ever more complex quantum systems becoming a reality, new scenarios are emerging where generalizations of the most foundational aspects of statistical quantum m…
