Hi all,
Tomorrow Lukas Brenner will tell us about their Semesterthesis with Philipp Kammerlander entitled 'Comparing Entropies via Erasure Processes on Multiple-Conserved-Quantity-Memories'. See below for the abstract. The talk will take place at 2pm in HIT E 41.1 or on Zoom: https://ethz.zoom.us/j/362994444.
Best, Ladina
%%%%%%% Abstract:
The relevance of memories in the context of thermodynamics was illustrated by their appearance in Szilard’s engine as a solution to Maxwell’s demon paradox. We formulize the notion of memories in the language of the Kammerlander framework, which provides the possibility to talk about thermodynamics of single and multiple conserved quantities. Memories are introduced as a family of thermodynamic systems which allow for generalized erasure processes i.e. resetting a memory to a reference state is achievable outside the realm of energy conservation. Such processes can be exploited in order to compare entropies induced by different conserved quantities. We demonstrate that a universal ratio of entropies is established when relating optimal erasure processes of memories.
