On the q-analogues of the Zassenhaus formula for dientangling exponential operators
R. Sridhar, R. Jagannathan
Katriel, Rasetti and Solomon introduced a -analogue of the Zassenhaus formula written as , where and …
Foldy-Wouthuysen transformation and a quasiparaxial approximation scheme for the scalar wave theory of light beams
Sameen Ahmed Khan, Ramaswamy Jagannathan, Rajiah Simon
The Foldy-Wouthuysen iterative diagonalization technique is applied to the Helmholtz equation to obtain a Hamiltonian description of the propagation of a monochromatic quasiparaxia…
Quadratic algebras :Three-mode bosonic realizations and applications
V. SunilKumar, B. A. Bambah, R. Jagannathan
Quadratic algebras of the type $\lsb Q_0, Q_\pm \rsb$ , $\lsb Q_+, Q_- \rsb$ are studied using three-mode bosonic realizations. Matrix repres…
Coherent States of Non-Linear Algebras:Application to Quantum Optics
V. SunilKumar, B. A. Bambah, R. Jagannathan +2
We present a general unified approach for finding the coherent states of polynomially deformed algebras such as the quadratic and Higgs algebras, which are relevant for various mul…
The Dirac equation approach to spin-1/2 particle beam optics
R. Jagannathan
The traditional approach to accelerator optics, based mainly on classical mechanics, is working excellently from the practical point of view. However, from the point of view of cur…
(P,Q)-Special Functions
R. Jagannathan
It is suggested that the (p,q)-hypergeometric series studied by Burban and Klimyk (in Integral Transforms and Special Functions, 2 (1994) 15 - 36) can be considered as a special ca…
