Measuring chaos in string scattering processes
We analyze the amplitudes of one highly excited string (HES) state with two or three tachyons in open bosonic string theory. We argue that these processes are chaotic by showing that the spacing ratios of successive peaks in the angular dependence of the amplitudes are distributed as predicted by the β-ensemble of random matrix theory (RMT). We show how the continuous parameter β depends on the level and helicity of the scattered HES state.
Measure for Chaotic Scattering Amplitudes
Abstract We propose a novel measure of chaotic scattering amplitudes. It takes the form of a log-normal distribution function for the ratios rn=δn/δn+1 of (consecutive) spacings δn between two (consecutive) peaks of the scattering amplitude. We show that the same measure applies to the quantum mechanical scattering on a leaky torus as well as to the decay of highly excited string states into two tachyons.
Turning rotating D-branes and black holes inside out their photon-halo
Abstract We extend our investigation on Couch-Torrence conformal inversions of black holes (BHs) and D-branes in various directions. We analyze asymptotically flat rotating charged BHs in D=4, in particular extremal rotating BHs in STU supergravity, and find invariance for special choices of the charges.
Carbonara sauce recipe by Massimo Bianchi
The chef's guide to making the classic and cream Italian pasta dish. Oct 18, 2019 11:00pm By Massimo Bianchi Serves 6 Print Spaghetti carbonara Carbonara is a traditional pasta dish from Rome. Some sources date it as far back as ancient Rome, while others say it was a post-WWII invention. There is as much controversy over how the name came about. 'Carbone' is Italian for coal, and some say this dish is named for the charcoal makers or coal miners with whom it was popular.
