Embedded Representations and Quasi-Dynamical Symmetry
Embedded Representations Quasi-Dynamical Symmetry
2011/7/20
This presentation explains why models with a dynamical symmetry often work extraordinarily well even in the presence of large symmetry breaking interactions. A model may be a caricature of a more real...
Statistical and dynamical fluctuations in the ratios of higher cumulants in relativistic heavy ion collisions
Statistical dynamical fluctuations ratios higher cumulants relativistic heavy ion collisions
2010/12/29
The statistical and dynamical fluctuations in the ratios of higher net-proton cumulants are firstly estimated and discussed. It is shown that the statistical fluctuations dominate the behavior of the ...
Instantons revisited: dynamical tunnelling and resonant tunnelling
Tunnelling dynamical tunnelling resonant tunnelling instantons semiclassical methods Wick rotation complex time
2010/4/8
Starting from trace formulae for the tunnelling splittings (or decay rates) analytically continued in the complex time domain, we obtain explicit semiclassical expansions in terms of complex trajector...
Dissipative and Fluctuating Dynamical Description of Nuclear Reactions
Dynamical Description Nuclear Reactions
2010/10/25
We address the description of nuclear dynamics at intermediate energies within the DYWAN model. New fluctuation-dissipation aspects are discussed and confronted with experimental results in nucleus-nu...
