Hamiltonian Dynamics

2

Phase Space vs State Space

  • Phase Space:
    • microscopic detail
    • high dimensionality
  • State Space:
    • macroscopic observables
    • low dimensionality
    • can have microstate degeneracy

3

Basic Assumption of Statistical Mechancis

All microstates are equally probable!

4

Degeneracy of (N, V, E) State Ω

Number of microstates with energy E, number of particles N, and volume V

5

Entropy Definition (microcanonical)

6
