Eigenstates of linear combinations of two boson creation and annihilation operators : An algebraic approach

P. Shanta, S. Chaturvedi, V. Srinivasan

Eigenstates of the linear combinations $a^2+\beta a^{†2}$ and $ab+\beta a^{†}{b}^{†}$ of two boson creation and annihilation operators are presented. The algebraic procedure giv…
