Partial Wave Decomposition in Friedrichs Model With Self-interacting Continua
Zhiguang Xiao, Zhi-Yong Zhou
We consider the nonrelativistic model of coupling bare discrete states with continuum states in which the continuum states can have interactions among themselves. By partial-wave d…

On Friedrichs Model with Two Continuum States
Zhiguang Xiao, Zhi-Yong Zhou
The Friedrichs model with one discrete state coupled to more than one continuum is studied. The exact eigenstates for the full Hamiltonian can be solved explicitly. The discrete st…

Virtual states and generalized completeness relation in the Friedrichs Model
Zhiguang Xiao, Zhi-Yong Zhou
We study the well-known Friedrichs model, in which a discrete state is coupled to a continuum state. By examining the pole behaviors of the Friedrichs model in a specific form fact…
