Phase diagram of the one-dimensional three-state Potts model with an additional mean-field interaction
Alessandro Campa, Vahan Hovhannisyan, Stefano Ruffo +1
We derive the phase diagram of the one-dimensional three-state Potts model with an additional mean-field interaction in the canonical ensemble. The free energy is obtained by mappi…

Lagrangian Homotopy Analysis Method using the Least Action Principle
Gervais Nazaire Chendjou Beukam, Jean Pierre Nguenang, Stefano Ruffo +1
The Homotopy Analysis Method (HAM) is a powerful technique which allows to derive approximate solutions of both ordinary and partial differential equations. We propose to use a var…
