Multi-dimensional chaos II: String scattering amplitudes, curve repulsion, and RMT

Massimo Bianchi, Maurizio Firrotta, Jacob Sonnenschein +1

Multi-dimensional chaos refers to processes described by erratic functions of several dynamical variables. In this letter we analyze the string scattering amplitudes of highly-exci…

One-loop mass corrections and decay widths of Type II heavy string states

Massimo Bianchi, Maurizio Firrotta, Lorenzo Grimaldi

We approach a systematic investigation of the one-loop mass corrections to (super-)string massive higher-spin states. While the imaginary part of the relevant amplitudes are finite…

Multi-dimensional chaos I: Classical and quantum mechanics

Massimo Bianchi, Maurizio Firrotta, Jacob Sonnenschein +1

We introduce the notion of multi-dimensional chaos that applies to processes described by erratic functions of several dynamical variables. We employ this concept in the interpreta…

From spectral to scattering form factor

Massimo Bianchi, Maurizio Firrotta, Jacob Sonnenschein +1

We propose a novel indicator for chaotic quantum scattering processes, the scattering form factor (ScFF). It is based on mapping the locations of peaks in the scattering amplitude…

Measuring chaos in string scattering processes

Massimo Bianchi, Maurizio Firrotta, Jacob Sonnenschein +1

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 th…

Measure for chaotic scattering amplitudes

Massimo Bianchi, Maurizio Firrotta, Jacob Sonnenschein +1

We propose a novel measure of chaotic scattering amplitudes. It takes the form of a log-normal distribution function for the ratios of (consecutive) spacings…
