Transient backbending behavior in the Ising model with fixed magnetization

, 2003
The physical origin of the backbendings in the equations of state of finite but not necessarily small systems is studied in the Ising model with fixed magnetization (IMFM) by means of the topological properties of the observable distributions and the ...

The thermodynamic approach to multifractal analysis

, 2011
Most results in multifractal analysis are obtained using either a thermodynamic approach based on existence and uniqueness of equilibrium states or a saturation approach based on some version of the specification property.
