Shortcuts to adiabaticity (STA) are fast routes to the final results of slow, adiabatic changes
of the controlling parameters of a system. The shortcuts are designed by a set of analytical …

Thermodynamics originated in the need to understand novel technologies developed by the
Industrial Revolution. However, over the centuries, the description of engines, refrigerators …

Heat engines convert thermal energy into mechanical work and generally involve a large
number of particles. We report the experimental realization of a single-atom heat engine. An …

The study of open quantum systems often relies on approximate master equations derived
under the assumptions of weak coupling to the environment. However when the system is …

Classical and quantum electronic circuits provide ideal platforms to investigate stochastic
thermodynamics, and they have served as a stepping stone to realize Maxwell's Demons …

The finite-time operation of a quantum heat engine that uses a single particle as a working
medium generally increases the output power at the expense of inducing friction that lowers …

We study a minimal quantum Otto heat engine, where the working medium consists of an
interacting few-body system in a harmonic trap. This allows us to consider the interaction …

We develop a deep learning (DL) framework assisted by differentiable programming for
discovery of optimal quantum control protocols under hard constraints. To that end, we use …

Real quantum heat engines lack the separation of time and length scales that is
characteristic for classical engines. They must be understood as open quantum systems in …

Local master equations are a widespread tool to model open quantum systems, especially
in the context of many-body systems. These equations, however, are believed to lead to …
