Problem 1. (total: 15 points) Again! Spin 1/2 system. Consider a system of N localized weakly interacting particles, each of spin 1/2 and magnetic moment , located in an external magnetic field H. The total number of states Q(E) lying in the energy range between E and E + SE N! SE n(E) : N E N E (2MH) ' (1) 2 2UH. ! (2 + 2UH) Using the expression for In Q(E) and the definition S = 0 In 1 /OE, find the relation between the absolute temperature T and the total energy E of this system
