Elective
3rd Cycle Studies
Recommended Prerequisites
Thermodynamics and Statistical Physics.
Teaching Methods
Lectures where the theory is complemented with practical applications that are physically relevant. There should be an emphasis in the application of these methods to practical problems in the tutorial classes.
Learning Outcomes
- To acknowledge that the correlations among different components of a system may lead to new laws of Physics.
- To differentiate between systems in equilibrium and systems out of equilibrium.
- To become acquainted with the equations that describe the dynamics of systems out of equilibrium (master equation, Langevin equation and Fokker-Planck equation).
- To be able to evaluate critical exponents and partition functions for systems in equilibrium and propagators for systems out of equilibrium. To evaluate the effect of non-linearity through perturbation theory and the renormalisation group.
