Consider the one-dimensional Ising model described in Example 16.2.

a) What is the average  as a function of temperature? Hint: what is the relation of this quantity to (E)?

b) As T = 0, how many ways are there for the energy to approach its ground state

energy?

c) Find an expression for the heat capacity. What is its behavior at both ܶ→0 and ܶ→∞? Explain. d) Find a temperature where the heat capacity is a maximum. What is the physical basis for this temperature?

a) Average Magnetization as a Function of Temperature The average magnetization, denoted as , is a measure of the average alignment of the spins in the Ising model. It can be calculated using the relation: = (1/Z) * ?(M * exp(-E/kT)) where Z is the partition function, M is the magnetization, E is the energy, k is the Boltzmann constant, and T is the temperature. The relation of the average magnetization to the energy can...
