Behaviour of large eigenvalues for the asymmetric quantum Rabi model
Mirna Charif, Ahmad Z. Fino, Lech Zieliński · Asymptotic Analysis · 2023
We prove that the spectrum of the asymmetric quantum Rabi model consists of two eigenvalue sequences [Formula: see text], [Formula: see text], satisfying a two-term asymptotic formula with error estimate of the form [Formula: see text], when m tends to infinity.
