Strings on conifolds from strong coupling dynamics: quantitative results

چکیده
Three quantitative features of string theory on AdS5×X5, for any (quasi)regular SasakiEinstein X5, are recovered exactly from an expansion of field theory at strong coupling around configurations in the moduli space of vacua. These configurations can be thought of as a generalized matrix model of (local) commuting matrices. First, we reproduce the spectrum of scalar Kaluza-Klein modes on X5. Secondly, we recover the precise spectrum of BMN string states, including a nontrivial dependence on the volume of X5. Finally, we show how the radial direction in global AdS5 emerges universally in these theories by exhibiting states dual to AdS giant gravitons.

Strings on conifolds from strong coupling dynamics, part I
A method to solve various aspects of the strong coupling expansion of the superconformal field theory duals of AdS5×X geometries from first principles is proposed. The main idea is that at strong coupling the configurations that dominate the low energy dynamics of the field theory compactified on a three sphere are given by certain non-trivial semi-classical configurations in the moduli space o...
متن کاملOpen-Closed String Duality from Orbifolded Conifolds
We study large N dualities for a class of N = 1 theories realized on type IIB D5 branes wrapping 2-cycles of local Calabi-Yau threefolds which is obtained from resolving orbifolded conifolds or as effective field theories on D4 branes in type IIA brane configurations. The field theory is N = 1 supersymmetric ∏U(Nij) Yang-Mills gauge theory. Strong coupling effects are analyzed in the deformed g...
متن کاملString Theory Dynamics in Various Dimensions
The strong coupling dynamics of string theories in dimension d ≥ 4 are studied. It is argued, among other things, that eleven-dimensional supergravity arises as a low energy limit of the ten-dimensional Type IIA superstring, and that a recently conjectured duality between the heterotic string and Type IIA superstrings controls the strong coupling dynamics of the heterotic string in five, six, a...
متن کاملThe Phases of 2D NCOS
We study the phases of the 1+1 dimensional Non-Commutative Open String theory on a circle. We find that the length scale of non-commutativity increases at strong coupling, the coupling in turn being dressed by a power of D-string charge. The system is stringy at around this length scale, with dynamics involving an interplay between the open and wrapped closed strings sectors. Above this energy ...
متن کاملSpatio-temporal Chaos and Vacuum Fluctuations of Quantized Fields
We consider deterministic chaotic models of vacuum fluctuations on a small (quantum gravity) scale. As a suitable small-scale dynamics, nonlinear versions of strings, so-called ‘chaotic strings’ are introduced. These can be used to provide the ‘noise’ for second quantization of ordinary strings via the Parisi-Wu approach of stochastic quantization. Extensive numerical evidence is presented that...
