**Unformatted text preview: **Physics 427 Fall 2008 Homework # 10 October 27; due November 3, 2008 1. 2. Kittel and Kroemer: Chapter 7; Problem 7; “Phonon condensation” Kittel and Kroemer: Chapter 7; Problem 8; “Energy, heat capacity, and entropy of a degenerate boson gas” Kittel and Kroemer: Chapter 7; Problem 13; “Chemical potential versus concentration” 3. 4. Consider a system of N weakly interacting particles, all of which are identical Fermions with spin 3/2 and mass m, moving with nonrelativistic speeds in two dimensions in a two‐dimensional square box with side L. a.) Find the chemical potential μ at temperature T = 0. b.) Find the average kinetic energy of the particles at temperature T = 0. ...
