Multi-Instantons and Exact-WKB Stokes Jumps in Multi-Well Quantum Mechanics
Alireza Behtash, Syo Kamata
We study the relation between the exact-WKB Delabaere--Dillinger--Pham Stokes jumps and the multi-instanton expansion of a one-dimensional potential with equal-depth minima. Fo…
Transasymptotics and hydrodynamization of the Fokker-Planck equation for gluons
A. Behtash, S. Kamata, M. Martinez +2
We investigate the non-linear transport processes and hydrodynamization of a system of gluons undergoing longitudinal boost-invariant expansion. The dynamics is described within th…
Global flow structure and exact formal transseries of the Gubser flow in kinetic theory
Alireza Behtash, Syo Kamata, Mauricio Martinez +1
In this work we introduce the generic conditions for the existence of a non-equilibrium attractor that is an invariant manifold determined by the long-wavelength modes of the physi…
Dynamical systems and nonlinear transient rheology of the far-from-equilibrium Bjorken flow
Alireza Behtash, Syo Kamata, M. Martinez +1
In relativistic kinetic theory, the one-particle distribution function is approximated by an asymptotic perturbative power series in Knudsen number which is divergent. For the Bjor…
Non-perturbative rheological behavior of a far-from-equilibrium expanding plasma
Alireza Behtash, C. N. Cruz-Camacho, Syo Kamata +1
For the Bjorken flow we investigate the hydrodynamization of different modes of the one-particle distribution function by analyzing its relativistic kinetic equations. We calculate…
Critical Points at Infinity, Non-Gaussian Saddles, and Bions
Alireza Behtash, Gerald V. Dunne, Thomas Schaefer +2
It has been argued that many non-perturbative phenomena in quantum mechanics (QM) and quantum field theory (QFT) are determined by complex field configurations, and that these cont…
