Large N Expansion from Fuzzy Ads 2

We study the quantum analogue of primary fields and their descendants on fuzzy AdS2, proposed in hep-th/0004072. Three-point vertices are calculated and shown to exhibit the conventional 1/N expansion as well as nonperturtive effects in large N , thus providing a strong consistency check of the fuzzy AdS2 model. A few new physical motivations for this model are also presented.

Semiquantum Chaos and the Large N Expansion

We consider the dynamical system consisting of a quantum degree of freedom A interacting with N quantum oscillators described by the Lagrangian L = 1 2 Ȧ + N ∑ i=1 { 1 2 ẋi − 1 2 (m + eA)xi } . (1) In the limit N → ∞, with eN fixed, the quantum fluctuations in A are of order 1/N . In this limit, the x oscillators behave as harmonic oscillators with a time dependent mass determined by the soluti...

A Large N expansion for Gravity

A Large N expansion for gravity is proposed. The scheme is based on the splitting of the Einstein-Hilbert action into the BF topological action plus a constraint. The method also allows to include matter fields. The relation between matter and non orientable fat graphs in the expansion is stressed; the special role of scalars is shortly discussed. The connections with the Holographic Principle ...

The emergence of AdS2 from quantum fluctuations

We have shown how the quantization of two-dimensional quantum gravity with an action which contains only a positive cosmological constant and boundary cosmological constants leads to the emergence of a spacetime which can be described as a constant negative curvature spacetime with superimposed quantum fluctuations. Talk given by W. Westra at the Eleventh Marcel Grossmann Meeting on General Rel...

The large-N expansion of unitary-matrix models

The general features of the 1/N expansion in statistical mechanics and quantum field theory are briefly reviewed both from the theoretical and from the phenomenological point of view as an introduction to a more detailed analysis of the large-N properties of spin and gauge models possessing the symmetry group SU(N )× SU(N ). An extensive discussion of the known properties of the single-link int...
