The idea is that temperature alway gives you an energy distribution p(E) =exp(-E/kT)*const. https://de.m.wikipedia.org/wiki/Boltzmann-Statistik https://de.m.wikipedia.org/wiki/Boltzmann-Statistik if you want to store information with one particle in a double well potential (tiny ist information storage), you need the barrier at least so high that you don't just hop to the next bin due to these fluctuation. This means you have to introduce a minimum energy effort depending on temperature needed to delete the information later. Ps statistical physics is slightly weird, not sure about a good book. Maybe Berkeley physics course vol 5 or so. About the Landauer principle itself I remember the paper actually to be quite accessible.
