Quadratic algebras :Three-mode bosonic realizations and applications

V. SunilKumar, B. A. Bambah, R. Jagannathan

Quadratic algebras of the type $\lsb Q_0, Q_\pm \rsb$ $=$ $\pm Q_{\pm}$ , $\lsb Q_+, Q_- \rsb$ $=$ $a Q_{0}^{2} + b Q_{0} + c$ are studied using three-mode bosonic realizations. Matrix repres…
