Colored diffraction catastrophes.
On fine scales, caustics produced with white light show vividly colored diffraction fringes. For caustics described by the elementary catastrophes of singularity theory, the colors are characteristic of the type of singularity. We study the diffraction colors of the fold and cusp catastrophes. The colors can be simulated computationally as the superposition of monochromatic patterns for differe...
متن کاملConfinement, Turbulence and Diffraction Catastrophes
Many features of the large Nc transition that occurs in the spectral density of Wilson loops as a function of loop area (observed recently in numerical simulations of Yang-Mills theory by Narayanan and Neuberger) can be captured by a simple Burgers equation used to model turbulence. Spectral shock waves that precede this asymptotic limit exhibit universal scaling with Nc, with indices that can ...
متن کاملProbing colored glass via qq̄ photoproduction II: diffraction
In this paper, we consider the diffractive photoproduction of quarkantiquark pairs in peripheral heavy ion collisions. The color field of the nuclei is treated within the Colored Glass Condensate model. The crosssection turns out to be very sensitive to the value of the saturation scale.

متن کاملClimate catastrophes
Climate catastrophes, which many times occurred in the geological past, caused the extinction of large or small populations of animals and plants. Changes in the terrestrial and marine biota caused by the catastrophic climate changes undoubtedly resulted in considerable fluctuations in global carbon cycle and atmospheric gas composition. Primarily, carbon dioxide and other greenhouse gas conten...
متن کاملClimate Change Catastrophes
Most studies that compare price and quantity controls for greenhouse gas emissions under uncertainty find that price mechanisms perform substantially better. In these studies, the benefits from reducing emissions are proportional to the level of reductions, and such linear benefits strongly favor price policies (Weitzman 1974). Catastrophic damages, however, challenge that intuition as conseque...
