Waiting times for entropic fluctuations in non-equilibrium processes
Abhishek Dhar (International centre for theoretical sciences, ICTS, Bangalore)
Nonequilibrium processes generate entropy. The total entropy generated in a fixed finite time interval is a fluctuating variable. A lot of recent work have looked at the probability of observing entropic fluctuations of different sizes in a fixed time interval. These distributions have been discussed in the context of fluctuation relations and large deviation functions. Here, we ask the question: how long does one have to wait to see an entropic fluctuation of a specified size ? We present some results on the waiting time distribution, in the context of some simple examples of non-equilibrium processes.
