Recurrence relations and path representations of matrix elements of an SU(1,1) algebra
C. V. Sukumar
It is shown that a SU(1,1) algebra may be used to provide a unified description of the simple hamonic oscillator and the angular momentum algebras and a class of other semi-infinit…
Squeezed states and Symplectic transformations
C. V. Sukumar
It is shown that the time evolution of the squeezed and displaced state may be obtained by solving the Heisenberg equation of motion of an appropriate operator and finding the eige…
Parametric evolution, addition of boundstates and generalised Lax hierarchies
C. V. Sukumar
The connection of the 'time' evolution of the eigenstates of the reflectionless potentials of the Lax hierarchy to the more general case of the 'time' evolution of the eigenstates…
Lax hierarchy, Solitons, Sumrules and a dual Lax hierarchy
C. V. Sukumar
It is shown that a set of functions which characterise the Lax hierarchy of non-linear equations may be represented in terms of the eigenstates of the potential which satisfies the…
