TL;DR
This paper extends the deformed boson scheme within the time-dependent variational method to systems with two types of bosons, exploring deformed coherent states related to su(2) and su(1,1) algebras.
Contribution
It introduces a generalized framework for deformed boson coherent states involving two boson types and analyzes their algebraic structures.
Findings
Deformation of coherent states for su(2) and su(1,1) algebras is systematically discussed.
Various forms of deformed algebras are explored, including the most popular form.
The approach enhances understanding of algebraic structures in quantum many-body systems.
Abstract
In this paper as a continuation of Part I, the case of two kinds of boson operators is treated. The deformation of the coherent states for the su(2)- and the su(1,1)-algebra and their related deformed algebras are discussed in various forms including the most popular form.
