Exact WKB analysis of inverted triple-well: resonance, PT-symmetry breaking, and resurgence
Syo Kamata, Tatsuhiro Misumi, Cihan Pazarbaşı +1
We study non-Hermitian quantum mechanics of an inverted triple-well potential within the exact WKB framework. For a single classical potential, different Siegert boundary condition…
QFT approach to dressed particle processes in preheating and non-perturbative mechanism in kinematically-forbidden regime
Hidetoshi Taya, Yusuke Yamada
We provide a quantum-field theoretic formulation of dressed particle dynamics that systematically include particle production and scattering/decay processes in the preheating era.…
Gyrohydrodynamics: Relativistic spinful fluid with strong vorticity
Zheng Cao, Koichi Hattori, Masaru Hongo +2
We develop a relativistic (quasi-)hydrodynamic framework, dubbed the gyrohydrodynamics, to describe fluid dynamics of many-body systems with spin under strong vorticity based on en…
Exact WKB analysis of the vacuum pair production by time-dependent electric fields
Hidetoshi Taya, Toshiaki Fujimori, Tatsuhiro Misumi +2
We study the vacuum pair production by a time-dependent strong electric field based on the exact WKB analysis. We identify the generic structure of a Stokes graph for systems with…
Fate of spin polarization in a relativistic fluid: An entropy-current analysis
Koichi Hattori, Masaru Hongo, Xu-Guang Huang +2
We derive relativistic hydrodynamic equations with a dynamical spin degree of freedom on the basis of an entropy-current analysis. The first and second laws of local thermodynamics…
