Query: Perspective: Quantum Thermodynamics   Classical thermodynamics is unrivalled in its range of applications and
relevance to everyday life. It enables a description of complex systems, made
up of microscopic particles, in terms of a small number of macroscopic
quantities, such as work and entropy. As systems get ever smaller, fluctuations
of these quantities become increasingly relevant, prompting the development of
stochastic thermodynamics. Recently we have seen a surge of interest in
exploring the quantum regime, where the origin of fluctuations is quantum
rather than thermal. Many questions, such as the role of entanglement and the
emergence of thermalisation, lie wide open. Answering these questions may lead
to the development of quantum heat engines and refrigerators, as well as to
vitally needed simple descriptions of quantum many-body systems.
