Unformatted text preview: Case when one cannot have more than one particle at a given site, for instance a vacancy Probability = 1/{1+exp([EE F ]/kT)} E F = Fermi energy E=E F , probability is 0.5 EE F >> kT tends to a Boltzmann distribution Also useful is the entropy for FD S = k{ xlnx + (1x)ln(1x)} 0 < x < 1 BoseEinstein, we won’t use in this class Case when one can have many identical particles, e.g. in a laser Elasticity Ended up talking about the importance of boundary conditions in setting up a problem...
