Higher-dimensional chaotic features and random matrix signatures following a local quench
Dmitry S. Ageev, Jacob Sonnenschein
We study the multidimensional erratic structure of correlation functions produced by local operator quenches in finite-volume free massive scalar field theory in dimensions 2 and 3…
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…
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…
On Chaos in QFT
Jacob Sonnenschein, Nadav Shrayer
In this note we explore the chaotic behavior of non-integrable QFTs and compare them to integrable ones. We choose as prototypes the double sine-Gordon and the sine-Gordon models.…
