Coupling of Higher Spin Gauge Fields to a Scalar Field in and their Holographic Images in the -Dimensional Sigma Model
T. Leonhardt, R. Manvelyan, W. Ruehl
The three-point functions of two scalar fields and the higher spin field of HS(4) on the one side and of their proposed holographic images and $\mathcal{J^{(\e…
Is it possible to construct exactly solvable models?
Oliver Haschke, Werner Ruehl
We develop a constructive method to derive exactly solvable quantum mechanical models of rational (Calogero) and trigonometric (Sutherland) type. This method starts from a linear a…
Construction of exactly solvable quantum models of Calogero and Sutherland type with translation invariant four-particle interactions
Oliver Haschke, Werner Ruehl
We construct exactly solvable models for four particles moving on a real line or on a circle with translation invariant two- and four-particle interactions.
Double Scaling Limits, Airy Functions and Multicritical Behaviour in O(N) Vektor Sigma Models
J. Maeder, W. Ruehl
O(N) vector sigma models possessing catastrophes in their action are studied. Coupling the limit N --> infinity with an appropriate scaling behaviour of the coupling constants, the…
