Berry-Phase and Symmetry of the Ground State in Dynamical Jahn-Teller Systems
Paolo De Los Rios, Nicola Manini
We show through selected examples, relevant to the physics of fullerene ions, that the presence of a Berry phase in dynamical Jahn-Teller systems does not guarantee the degeneracy…
Self-organized criticality in deterministic systems with disorder
Paolo De Los Rios, Angelo Valleriani, Jose Luis Vega
Using the Bak-Sneppen model of biological evolution as our paradigm, we investigate in which cases noise can be substituted with a deterministic signal without destroying Self-Orga…
Self-Organized Criticality Driven by Deterministic Rules
Paolo De Los Rios, Angelo Valleriani, José Luis Vega
We have investigated the essential ingredients allowing a system to show Self Organized Criticality (SOC) in its collective behavior. Using the Bak-Sneppen model of biological evol…
Dynamical Jahn-Teller Effect and Berry Phase in Positively Charged Fullerene I. Basic Considerations
P. De Los Rios, N. Manini, E. Tosatti
We study the Jahn-Teller effect of positive fullerene ions C and C. The aim is to discover if this case, in analogy with the negative ion, possesses…
