ab: Summary: We prove a number of identities relating the sofic entropy of a
    certain class of non-expansive algebraic dynamical systems, the sofic
    entropy of the Wired Spanning Forest and the tree entropy of Cayley
    graphs of residually finite groups. We also show that homoclinic points
    and periodic points in harmonic models are dense under general
    conditions.
