1-r' Problem 16.12 (30 pts) This chapter examines the two-state system but consider instead the infinite-state system consisting of N non-interacting particles. Each particle i can be in one of an infinite number of states designated by an integer, n; = 0,1,2, .... The energy of particle i is given by a = en; where e is a constant. Note: you may need the series sum Li-ori = a) If the particles are distinguishable, compute QIT,N) and A(T,N) for this...
1. Quick Exercises (a) In lecture 15, we showed that the canonical partition function, Q, is related to the Helmholz free energy: A = -kTinQ. Using the fundamental thermo- dynamic relation of Helmheltz free energy i.e. dA = -SAT - PDV + pdN), express P, and p in terms of Q. (b) The canonical partition function for N non-interacting, indistinguishable parti- cles in volume V at temperature T is given by Q(N,V,T) = where where q(V.T) is the partition function...

trying for last time :( Can anyone please help and explain how to do this task ? Thank you Q4 (QUANTUM IDEAL GASES) Is the statement "Given a two-spinless-fermion system, and two orbitals o labeled by quantum numbers a, b, the two-body wavefunction (1,2 represent the particle variables) V (1, 2) = 0a(1)$a (2) - 06(1)$6(2) +0a(1)º(2) - 06(1)$a(2) correctly describes a possible state of the system” true or false ? Explain your answer (0.5p). 4b) Consider a Fermi gas...
