The above article is about a family of Maxwell–like demons for which there are correlations between “information–bearing degrees of freedom” (quoting from the authors’ description of their work). More precisely, it is another paper (in quite a long series of recent papers) about an extended second law for a family of models of systems that consist of an information reservoir (in the form of a running digital tape) and it is shown that the amount of heat that can be transformed into work, done…

A solvable model of a thermodynamic ratchet that leveraged information to convert thermal energy to work and one of its longest-lived counterexamples—Maxwell’s Demon is introduced.


Sequence complexity and work extraction
We consider a simplified version of a solvable model by Mandal and Jarzynski, which constructively demonstrates the interplay between work extraction and the increase of the Shannon entropy of an
