Yang-Lee and Fisher zeros generalized on some far-from-equilibrium systems (2008)

Sargsyan, K. G.

A generalization of the Yang-Lee and Fisher zeros on far-from-equilibrium systems coupled with two thermal baths is proposed. The Yang-Lee zeros were obtained for minimal models which exhibit...

Topological Disorder in Spin Models on Hierarchical Lattices (2008)

Ananikian, N. S., Sargsyan, K. G.

A general approach for the description of spin systems on hierarchial lattices with coordination number $q$ as a dynamical variable is proposed. The ferromagnetic Ising model on the Bethe lattice was...
