Lyapunov exponent for products of random Ising transfer matrices: the balanced disorder case
Giambattista Giacomin, Rafael L. Greenblatt
We analyze the top Lyapunov exponent of the product of sequences of two by two matrices that appears in the analysis of several statistical mechanics models with disorder: for exam…
