Microcanonical ensemble

Ensemble variables[edit]

(One component system, 3-dimensional system, ... ):

  • : number of particles
  • : is the volume
  • : is the internal energy (kinetic + potential)

Partition function[edit]

where:

  • represents the 3N Cartesian position coordinates.
  • represents the 3N momenta.
  • represents the Hamiltonian, i.e. the total energy of the system as a function of coordinates and momenta.

Thermodynamics[edit]

where:

  • is the entropy.
