• ### Landauer's Principle and the balance equation

February 29, 2016

I’ve been working on my thesis over reading week, and I think I’ve finished my introduction to Landauer’s Principle. I ended up writing a pretty detailed derivation of the balance equation, and thus Landauer’s bound, so I thought it might be useful to post here.

Landauer's principle states that there is a minimal energetic cost for a state transformation $\sysstate\init \to \sysstate\fin$ on a system $\sys$ via the action of a thermal reservoir $\env$ at temperature $(k_B\beta)\inv$.
