Hi, This week's seminar talk will be given by Johan Aaberg: Tuesday, Nov. 9, 17:00 in CAB H 53 at Zentrum. Best regards, Stefan _______________________________________________________________ Title: Yet another work extraction Abstract: In lack of better ideas I am going to torment you with another of those "work extraction" and "erasure" problems. This investigation provides a small step towards understanding single-shot erasure and work extraction in systems with non-trivial Hamiltonians. I have to admit that this is going to be somewhat physics flavored, but I will try to keep myself in check. In any case, the pain will be very brief; I will only present the model and the main results. _______________________________________________________________
