Diagram methods for reduction factor calculations in Jahn-Teller systems
A novel method is developed for the description and calculation of Ham reduction factors in 'Jahn-Teller active' systems which are weakly coupled to many lattice modes. Diagrammatic many-body perturbation theory for finite temperatures is combined with diagrammatic group theory into a cohe...
