Long-range Tail Dependence: Edm vs. Extremogram
The dependence of large values in a stochastic process is an important topic in risk, insurance and finance. The idea of risk contagion is based on the idea of large value dependence. The Gaussian copula notoriously fails to capture this phenomenon. Two notions in a process context which attempt to summarize this extremal dependence in a function comparable to a sample correlation function are ...
متن کاملA weak, attractive, long-range force in Higgs condensates
Due to the peculiar nature of the underlying medium, density fluctuations in a ‘Higgs condensate’ are predicted to propagate for infinitely long wavelengths with a group velocity cs → ∞. On the other hand, for any large but finite cs there is a weak, attractive 1/r potential of strength 1 cs and the energy spectrum deviates from the purely massive form √ p2 +M2 h at momenta smaller than δ ∼ Mh ...
متن کاملHomogeneous Cooling with Repulsive and Attractive Long-Range Potentials
The interplay between dissipation and long-range repulsive/attractive forces in homogeneous, dilute, mono-disperse particle systems is studied. The pseudo-Liouville operator formalism, originally introduced for hard-sphere interactions, is modified such that it provides very good predictions for systems with weak long-range forces at low densities, with the ratio of potential to fluctuation kin...
متن کاملHomogeneous Cooling with Repulsive and Attractive Long-range Interactions
In granular matter, consisting of discrete particles, long-range interactions imply that each of the particles is interacting with all others. For many charged granular materials with Coulomb repulsion or large-scale gravitationally attractive systems, a Molecular Dynamics environment is developed. In granular systems with long-range interaction forces and dissipative collisions, both effects c...
متن کاملScaling of dynamics with the range of interaction in short-range attractive colloids.
We numerically study the dependence of the dynamics on the range of interaction Delta for the short-range square well potential. We find that, for small Delta, dynamics scale exactly in the same way as thermodynamics, both for Newtonian and Brownian microscopic dynamics. For interaction ranges from a few percent down to the Baxter limit, the relative location of the attractive-glass line and th...
