Further results on the free energy of the random field Ising chain in the case of centered disorder

Orphée Collin

We study the expansion of the limiting free energy density of the random field Ising chain with centered IID disorder and homogeneous coupling parameter, when the latter goes to in…

On the Lyapunov exponent for the random field Ising transfer matrix, in the critical case

Orphée Collin, Giambattista Giacomin, Rafael L. Greenblatt +1

We study the top Lyapunov exponent of a product of random $2 \times 2$ matrices appearing in the analysis of several statistical mechanical models with disorder, extending a previo…
