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…
Exact WKB in all sectors II: Potentials with non-degenerate saddles
Tatsuhiro Misumi, Cihan Pazarbaşı
We discuss the exact quantization of general one-dimensional potentials in view of the exact-WKB formalism. Building on our previous work, we perform analytic continuations across…
Polyakov Model in 't Hooft flux background: A quantum mechanical reduction with memory
Cihan Pazarbaşı, Mithat Ünsal
We construct a compactification of Polyakov model on down to quantum mechanics which remembers non-perturbative aspects of field theory even at an arbitrari…
Pair Production in Real Proper Time and Unitarity Without Borel Ambiguity
Cihan Pazarbaşı
The pair production of scalar particles in electromagnetic background fields is analyzed using real proper time formulation of 1-loop effective action. After explaining how real pr…
