报告简介：The adaptive perturbation method decomposes a Hamiltonian by the diagonal elements and non-diagonal elements of the Fock state. The diagonal elements of the Fock state are solvable but can contain the information about interacting constants. The exact solution for each perturbed term can obtain in the harmonic oscillator with the interacting potential, λ1x4/6+λ2x6/120, where λ1 and λ2 are coupling constants, and x is the position operator. We demonstrate the accurate study of the spectrum and ⟨x2⟩ up to the next leading-order correction. In particular, we study a similar problem of Higgs field from the inverted mass term to demonstrate the possible non-trivial application of particle physics.
