Query: Optimal reversible flipping strategies for kinetic Ising models   There is a deep connection between thermodynamics, information and work
extraction. Ever since the birth of thermodynamics, various types of Maxwell
demons have been introduced in order to deepen our understanding of the second
law. Thanks to them it has been shown that there is a deep connection between
thermodynamics and information, and between information and work in a thermal
system, which usually helps in resolving apparent paradoxes arising when demons
are present. Here we show that even in a complex system such as an Ising model,
a being with perfect information but satisfying the laws of thermodynamics can
extract energy by applying optimal (but local) strategies of spin flipping. We
call these entities, in contrast to Maxwell's demons which have physical
superpowers, $\textit{thermodynamic kobolds}$.
