Fusion rings with few degrees

Few degrees of freedom

The climate change conference in Copenhagen last month went to the wire with no agreement emerging until late on the last day. Ahead of the meeting, President Obama was expected to make a significant financial commitment to a global climate protection fund rather than improve on his provisional offer of cutting emissions by 4 per cent on 990 levels by 2020. The final accord declared deep cuts i...

Nonsolvable groups with few character degrees

Fluctuations in partitioning systems with few degrees of freedom.

We study the behavior of a moving wall in contact with a particle gas and subjected to an external force. We compare the fluctuations of the system observed in the microcanonical and canonical ensembles, by varying the number of particles. Static and dynamic correlations signal significant differences between the two ensembles. Furthermore, velocity-velocity correlations of the moving wall pres...

Electronic structure of few-electron concentric double quantum rings

The ground state structure of few-electron concentric double quantum rings is investigated within the local spin density approximation. Signatures of inter-ring coupling in the addition energy spectrum are identified and discussed. We show that the electronic configurations in these structures can be greatly modulated by the inter-ring distance: At short and long distances the low-lying electro...

Fusion rings for degenerate minimal models

We study fusion rings for degenerate minimal models (p = q case) for N = 0 and N = 1 (super)conformal algebras. We consider a distinguished family of modules at the level c = 1 and c = 3 2 and show that the corresponding fusion rings are isomorphic to the representation rings for sl(2, C) and osp(1|2) respectively.
