Statistical Physics of Non Thermal Phase Transitions : From Foundations to Applications Statistical physics can be used to better understand non thermal complex systems phenomena such as stock market crashes revolutions in society and in science fractures in engineered materials and in the Earth’s crust catastrophes traffic jams petroleum clusters polymerization self organized criticality and many others exhibit behaviors resembling those of thermodynamic systems. In particular many of these systems possess phase transitions identical to critical or spinodal phenomena in statistical physics. The application of the well developed formalism of statistical physics to non thermal complex systems may help to predict and prevent such catastrophes as earthquakes snow avalanches and landslides failure of engineering structures or economical crises. This book addresses the issue step by step from phenomenological analogies between complex systems and statistical physics to more complex aspects such as correlations fluctuation dissipation theorem susceptibility the concept of free energy renormalization group approach and scaling. Fractals and multifractals the Ising model percolation damage phenomena critical and spinodal phase transitions crossover effects and finite size effects are some of the topics covered in Statistical Physics of Non Thermal Phase Transitions
