In nuclear physics, random matrices were introduced by Eugene Wigner to model the nuclei of heavy atoms. Wigner postulated that the spacings between the lines in the spectrum of a heavy atom nucleus should resemble the spacings between the eigenvalues of a random matrix, and should depend only on the symmetry class of the underlying evolution. In solid-state physics, random matrices model the behaviour of large disordered Hamiltonians in the mean-field approxi… WebRandom Matrix Theory andζ(1/2 +it)59 that is, in the limit asT, the height up the critical line, tends to infinity, the value distri- butions of the real and imaginary parts of logζ(1/2 +iT)/ (1/2)loglogTeach tend independently to a Gaussian with unit variance and zero mean.
