On the geometry of classically integrable two-dimensional non-linear sigma models
نویسنده
چکیده
A master equation expressing the classical integrability of two-dimensional non-linear sigma models is found. The geometrical properties of this equation are outlined. In particular, a closer connection between integrability and T-duality transformations is emphasised. Finally, a whole new class of integrable non-linear sigma models is found and all their corresponding Lax pairs depend on a spectral parameter. ∗e-mail: [email protected]

Non-linear Sigma Models on a Half Plane
In the context of integrable field theory with boundary, the integrable non-linear sigma models in two dimensions, for example, the O(N ), the principal chiral, the CP and the complex Grassmannian sigma models are discussed on a half plane. In contrast to the well known cases of sine-Gordon, non-linear Schrödinger and affine Toda field theories, these non-linear sigma models in two dimensions a...

A non-technical overview on gravity in two dimensions is provided. Applications discussed in this work comprise 2D type 0A/0B string theory, Black Hole evaporation/thermodynamics, toy models for quantum gravity, for numerical General Relativity in the context of critical collapse and for solid state analogues of Black Holes. Mathematical relations to integrable models, non-linear gauge theories...
متن کاملChaotic Spectra of Classically Integrable Systems
We prove that any spectral sequence obeying a certain growth law is the quantum spectrum of an equivalence class of classically integrable non-linear oscillators. This implies that exceptions to the BerryTabor rule for the distribution of quantum energy gaps of classically integrable systems, are far more numerous than previously believed. In particular we show that for each finite dimension k,...
متن کاملNew classical r-matrices from integrable non-linear sigma models Contribution presented at the XIX ICGTMP Salamanca
Non linear sigma models on Riemannian symmetric spaces constitute the most general class of classical non linear sigma models which are known to be integrable. Using the the current algebra structure of these models their canonical structure is analysed and it is shown that their non ultralocal fundamental Poisson bracket relation is governed by a field dependent non antisymmetric r-matrix obey...

We propose a graphic method to derive the classical algebra (Dirac brackets) of non-local conserved charges in the two-dimensional supersymmetric non-linear O(N) sigma model. As in the purely bosonic theory we find a cubic Yangian algebra. We also consider the extension of graphic methods to other integrable theories. 1 Introduction Non-linear sigma models [1-3] are prototypes of a remarkable c...
