Detailed Jarzynski Equality applied on a Logically Irreversible Procedure

Abstract : A single bit memory system is made with a brownian particle held by an optical tweezer in a double-well potential. For a memory erasure procedure, which is a logically irreversible operation, a detailed Jarzynski Equality is verified, retrieving the Landauer limit independently of the work done on the system. For the two separated subprocesses, i.e. the transition from state 1 to state 0 and the transition from state 0 to state 0, the Jarzynski equality does not hold but the generalized version links the work done on the system to the probability that the it returns to its initial state under the time-reversed procedure.
