Isothermal susceptibility of the ising chain more insight into the properties of the ising chain can be found by understandine the temperture dependence of the isothermal susceptibility x. (a) calculate y using (5.83). (b) what is the limiting behavior of x in the limit t - o for h > 0? (c) show that the limiting behavior of the zero-field susceptibility in the limit! t- ois y d. (the zero-field susceptibility is found by calculating! the susceptibility for h 0 and then taking the limit h → 0 before other limits such as t 0 are taken.) express the limiting behavior in terms of the correlation length. why does x diverge as t - 0?
