A methodology is given to determine the effect of different mass distributions for triatomic reactions using the geometry of shape space. Atomic masses are incorporated into the non-Euclidean shape space metric after the separation of rotations. Using the equations of motion in this non-Euclidean shape space, an averaged field of velocity-dependent fictitious forces is determined. This force fi...

This paper studies a flexible hierarchic design approach of large processor networks with distributed media access. The cluster-based interconnection combines passive metal buses and passive optical star couplers at two hierarchic levels, independently employing interleaved TDMA for conflict-free interprocessor communication. The system delay analysis highlights the tradeoffs of arbitrarily com...

We consider the small-volume dynamics of nonsupersymmetric orbifold and orientifold field theories defined on a three-torus, in a test of the claimed planar equivalence between these models and appropriate supersymmetric " parent models ". We study one-loop effective potentials over the moduli space of flat connections and find that planar equivalence is preserved for suitable averages over the...

It has been suggested that the enlarged spin susceptibility in topological insulators, described by Van Vleck's formalism, accounts for ferromagnetism of bismuth-antimony chalcogenides doped with transition metal impurities. In contrast, earlier studies HgTe and related systems pointed out interband analog Ruderman-Kittel-Kasuya-Yosida interaction (the Bloembergen-Rowland mechanism) leads to an...
