Abstract We study the problem of energetic cost information erasure by looking at it through lens Jarzynski equality. observe that Landauer bound, $$\langle W \rangle \ge kT \ln 2$$ ? W ? ? k T ln 2</m...

In this paper we present an analysis of information transfer based on Landauer s principle (i.e., erasure of information is associated with an increase in entropy), as well as considerations of analyticity and causality. We demonstrate that holomorphic functions allowing complete analytic continuation cannot propagate any information, such that information transfer only occurs with analytic fun...
