Generalised Eisenhart lift of the Toda chain
Abstract
The Toda chain of nearest neighbour interacting particles on a line can be described both in terms of geodesic motion on a manifold with one extra dimension, the Eisenhart lift, or in terms of geodesic motion in a symmetric space with several extra dimensions. We examine the relationship between these two realisations and discover that the symmetric space is a generalised, multiparticle Eisenhart lift of the original problem that reduces to the standard Eisenhart lift. Such generalised Eisenhart lift acts as an inverse KaluzaKlein reduction, promoting coupling constants to momenta in higher dimension. In particular, isometries of the generalised lift metric correspond to energy preserving transformations that mix coordinates and coupling constants. A byproduct of the analysis is that the lift of the Toda Lax pair can be used to construct higher rank Killing tensors for both the standard and generalised lift metrics.

This paper is devoted to the specific question of constructing soliton solutions to the equations of the periodic Toda chain on the basis of the formalism of the scalar LA pair, i.e., the system of linear equations of higher dimensions for one unique scalar function psi, the condition of compatibility of the system being the equations of the generalized periodic Toda chain. With each representation of a semisimple algebra there is associated a scalar LA pair. The number of equations in it exceeds by unity the dimension of the corresponding representation, and the maximal degree of the derivative in themore »

Chaos and nonlinear modes in a perturbed Toda chain
The role of spatially coherent modes in a chaotic state of the damped and driven Toda chain is investigated with the help of the scattering transform. 
2 + 1 Toda chain. I. Inverse scattering method
A formal scheme of the inverse scattering method is constructed for the2 + 1 Toda chain in the class of rapidly decreasing Cauchy data. Application of the inverse scattering method to the twodimensional infinite Toda chain was made difficult by the circumstance that this system is a (2 + 1)dimensional object, i.e., possesses time and two spatial variables, the role of one of these being played by the chain site number. Because of this, our information about the 2 + 1 Toda chain was limited to a rich set of particular solutions of soliton type obtained in the cycle ofmore » 
Aspects of the inverse problem for the Toda chain
We generalize Babelon's approach to equations in dual variables so as to be able to treat new types of operators which we build out of the subconstituents of the model's monodromy matrix. Further, we also apply Sklyanin's recent monodromy matrix identities so as to obtain equations in dual variables for yet other operators. The schemes discussed in this paper appear to be universal and thus, in principle, applicable to many models solvable through the quantum separation of variables.
