comment Interacting representation of the Poincaré group
@BGal One can easily find an interaction term, and construct the expressions of the interacting algebra in terms of the field variables. For example in a scalar field theory \mathcal{H} = \lambda \phi^4 is a possible interaction term, and it is easy to exactly construct interacting Poincaré generators in terms of the field and its derivatives. Finding a representation on the other hand would mean to find a Hilbert space on which the action of the interacting Poincaré generators is completely known.

comment What are the solution spaces of Nonlinear Schrödinger equations?
@Arnold, please see the Crncovic-Witten and Zuckerman's articles given in Urs Schreiber's answer physics.stackexchange.com/questions/26883/…. The Crncovic-Witten's link is not working, but you can find their article in the book: books.google.co.il/…

comment Mathematically challenging areas in Quantum information theory and quantum cryptography
Coherent states which are widely used in quantum cryptography, have a geometric origin (Bargmann space). Please see for example Ma's thesis: web.williams.edu/go/math/sjmiller/public_html/crypto/handouts/…
