Nonequilibrium formulation of varying-temperature bit erasure
Stephen Whitelam
Landauer's principle states that erasing a bit of information at fixed temperature T costs at least kT ln 2 units of work. Here we investigate erasure at varying temperature, to wh…

Free-energy estimates from nonequilibrium trajectories under varying-temperature protocols
Stephen Whitelam
The Jarzynski equality allows the calculation of free-energy differences using values of work measured from nonequilibrium trajectories. The number of trajectories required to accu…
