ABSTRACT | Microcanonical analysis is a powerful method that can be used to generalize the concept of
phase transitions to finite-size systems. However, microcanonical analysis has only been
applied to equilibrium systems. I show that it is possible to conduct the microcanonical analysis
of a finite-size nonequilibrium system by generalizing the concept of microcanonical entropy.
A one-dimensional asymmetric diffusion process is studied as an example for which such a
generalized entropy can be explicitly found, and the microcanonical method is used to define
a phase transition for the finite-size nonequilibrium system.
