Open quantum systems (OQSs) cannot always be described with the Markov approximation,
which requires a large separation of system and environment time scales. An overview is …

The quantum Otto cycle serves as a bridge between the macroscopic world of heat engines
and the quantum regime of thermal devices composed from a single element. We compile …

The inexorable miniaturisation of technologies, the relentless drive to improve efficiency and
the enticing prospect of boosting performance through quantum effects are all compelling …

The working substance fueling a quantum heat engine may contain coherence in its energy
basis, depending on the dynamics of the engine cycle. In some models of quantum Otto heat …

When deriving a master equation for a multipartite weakly-interacting open quantum
systems, dissipation is often addressed locally on each component, ie ignoring the coherent …

We study bounds on ratios of fluctuations in steady-state time-reversal energy conversion
devices. In the linear response regime, we prove that the relative fluctuations (precision) of …

We study the performance of three-level quantum absorption refrigerators, paradigmatic
autonomous quantum thermal machines, and reveal central impacts of strong couplings …

The thermodynamic uncertainty relation, originally derived for classical Markov-jump
processes, provides a tradeoff relation between precision and dissipation, deepening our …

Thermal machines perform useful tasks, such as producing work, cooling, or heating by
exchanging energy, and possibly additional conserved quantities such as particles, with …

Collective behavior, where a set of elements interact and generate effects that are beyond
the reach of the individual noninteracting elements, is always of great interest in physics …
