Consider a one-dimensional Ising model with N spins, at very loOw temperatures when almost all the spins are aligned parallel to each other. There will be a few spin flips with each flip costino an energy 2J. In a configuration with r spin flips, the energy of the system is E = -NJ + 2rJ and the number of configuration is NC; r varies from 0 to N. The partition function is N (A) T (kT (B) eNJ/kaT (C) sinh N J N kT (D) COsh kT
