Fixing Divergence in Carleman Linearization via Analytical Continuation
Mingshuo Zhu, Hayato Higuchi, Hokuto Iwakiri +4
Nonlinear differential equations play a crucial role in modeling a wide range of phenomena, yet their solutions remain notoriously difficult to obtain. With the rapid development o…
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…
On exact-WKB analysis, resurgent structure, and quantization conditions
Naohisa Sueishi, Syo Kamata, Tatsuhiro Misumi +1
There are two well-known approaches to studying nonperturbative aspects of quantum mechanical systems: Saddle point analysis of the partition functions in Euclidean path integral f…
problem in resurgence
Naohisa Sueishi
This paper considers the problem, which is the divergent behavior of the ground state energy of asymmetric potential in quantum mechanics, which is calculated with semi-class…
