This result is obtained by computing the ... WebMar 1, 2014 · The SK model was solved by means of the replica method and, consequently, it was originally thought that it was exactly solvable, although Sherrington and Kirkpatrick were aware that it suffers from a serious drawback, in that, it possesses a negative entropy at zero temperature, specifically S (T = 0 K) = − N k / 2 π.
