Consider an object containing 9 one-dimensional oscillators (this object could represent a model of 3 atoms in an Einstein solid). There are 4 quanta of vibrational energy in the object.
(a) How many microstates are there, all with the same energy?
(b) If you examined a collection of 48000 objects of this kind, each containing 4 quanta of energy, about how many of these objects would you expect to find in the microstate 000000004?

Consider a one-dimensional tight binding model of electrons hopping between atoms. Let the distance between atoms be called a, and here let us label the atomic orbital on atom n as In) for n-1,..N (you may assume orthonormality of orbitals, i.e, (n|m) -8nm) Suppose there is an on-site energy є and a hopping matrix element-t. In other words, suppose 〈nlH1m)=ε for n-mand (IH1m)=-t for n-m±1. (b) How many different eigenstates are there in this system?
