We study the thermodynamical properties of a Dicke model with classical spins. As in the quantum case, the model exhibits a phase transition associated with the spontaneous breaking of the gauge symmetry. We calculate the thermodynamical equilibrium photon state in a relatively simple way both at an

Using mean-field renormalization group (MFRG) and surface-bulk mean-field renormalization group (SBMFRG) methods, we study the critical properties of classical Heisenberg and XY models. We show the exact result that there is no finite temperature phase transition in one dimension and very good value
The critical behaviour of an exactly solvable model with developed classical and quantum fluctuations depending on the temperature, the quantum parameter and the space dimension, is studied. The critical exponents on the whole phase diagram, including two multicritical points (quantum and classical)
