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...
متن کاملOn the Large R - charge Expansion in N = 2 Superconformal Field Theories
In this note we study two point functions of Coulomb branch chiral ring elements with large R-charge, in quantum field theories with N = 2 superconformal symmetry in four spacetime dimensions. Focusing on the case of one-dimensional Coulomb branch, we use the effective-field-theoretic methods of [1], to estimate the two-point correlation function Yn ≡ |x − y|O 〈 (O(x)) (Ō(y)) 〉 in the limit whe...
متن کاملPuzzles at Large N
We consider the AdS/CFT correspondence and find that essentially all " single particle " primary fields with higher spin, predicted from the CFT side are missing from the Kaluza-Klein excitations of the AdS supergravity. Some 2 and 4 dimensional CFT's are used to illustrate the puzzle. In the 2 dimensional case, the high mass extension of these missing states gives rise to the macroscopic entro...
متن کاملA 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 ...
متن کاملLarge 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.
