The Microcanonical Entropy model considers an isolated system consisting of N identical, non-interacting quantum particles energy E. We wish to determine the entropy of the system S(N,E).
For fixed total energy E, we consider a system of N distinguishable particles to be composed of a subsystem of (N ? 1) particles and a subsystem of 1 particle. The system comprising N particles with energy E. (1,E?) are the degeneracies of the single particle levels with energy E? less than or equal to E. The number of microstates is used to compute entropy when N is small and a recursive algorithm is used to construct the entropy when N is large. The model displays the entropy S(N,E) and the computation time as users vary the number of particles N and the total energy E.
The Microcanonical Entropy model was developed by Wolfgang Christian, Trisha Salagaram, and Nithaya Chetty using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_stp_MicrocanonicalEntropy.jar file will run the program if Java is installed.
