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…
Exact-WKB Analysis of Two-level Floquet Systems
Toshiaki Fujimori, Syo Kamata, Tatsuhiro Misumi +2
We explore the application of the exact Wentzel-Kramers-Brillouin (WKB) analysis to two-level Floquet systems and establish a systematic procedure to calculate the quasi-energy and…
Resurgence for the non-conformal Bjorken flow with Fermi-Dirac and Bose-Einstein statistics
Syo Kamata
We consider resurgence for the nonconformal Bjorken flow with Fermi-Dirac and Bose-Einstein statistics on the extended relaxation-time approximation. We firstly consider full forma…
Novel features of attractors and transseries in non-conformal Bjorken flows
Syo Kamata, Jakub Jankowski, Mauricio Martinez
In this work we investigate the impact of conformal symmetry breaking on hydrodynamization of a far-from-equilibrium fluid. We find a new kind of transseries solutions for the non-…
All-order Resurgence from Complexified Path Integral in a Quantum Mechanical System with Integrability
Toshiaki Fujimori, Syo Kamata, Tatsuhiro Misumi +2
We discuss all-order transseries in one of the simplest quantum mechanical systems: a U(1) symmetric single-degree-of-freedom system with a first-order time derivative term. Follow…
Exact-WKB analysis for SUSY and quantum deformed potentials: Quantum mechanics with Grassmann fields and Wess-Zumino terms
Syo Kamata, Tatsuhiro Misumi, Naohisa Sueishi +1
Quantum deformed potentials arise naturally in quantum mechanical systems of one bosonic coordinate coupled to Grassmann valued fermionic coordinates, or to a topological Wes…
