Variational Perturbation Approach to Resonance-State Wave Functions
T. Tanaka
The variational perturbation theory for wave functions, which has been shown to work well for bound states of the anharmonic oscillator, is applied to resonance states of the anhar…

Optimized Perturbation Theory for Wave Functions of Quantum Systems
T. Hatsuda, T. Kunihiro, T. Tanaka
The notion of the optimized perturbation, which has been successfully applied to energy eigenvalues, is generalized to treat wave functions of quantum systems. The key ingredient i…
