Semiclassical Quantization of Giant Gravitons
نویسندگان
چکیده
We study excited spherical branes (“giant gravitons”) in AdS × S spacetimes with background flux. For large excitation, these branes may be treated semiclassically. We compute their spectra using Bohr-Sommerfeld quantization and use the AdS/CFT correspondence to relate them to anomalous dimensions in the dual field theory at strong coupling, expressed as a series expansion in powers of 1/N . These effects resemble those due to k-body forces between quarks in Hartree-Fock models of baryons at large N . For branes expanded in AdS, we argue that the anomalous dimensions are due to loop corrections to the effective action.

Dilatation operator and the Super Yang-Mills duals of open strings on AdS Giant Gravitons
We study the one-loop anomalous dimensions of the Super Yang-Mills dual operators to open strings ending on AdS giant gravitons. AdS giant gravitons have no upper bound for their angular momentum and we represent them by the contraction of scalar fields, carrying the appropriate R-charge, with a totally symmetric tensor. We represent the open string motion along AdS directions by appending to t...
متن کاملBasis states for gravitons in non-perturbative loop representation space
A relation between the non-perturbative loop representation space (for use of exact quantization of general relativity) and the semi-classical loop representation space (for use of approximate quantization of general relativity with a flat background spacetime) is studied. A sector of (approximate) states and a sector of operators in the non-perturbative loop representation space are made relat...

We propose an exact, finite N formula for the partition function over 1/4 BPS states in the conformal field theory on the world volume of N coincident M5 branes, and 1/8 BPS states in the theory of N conincident M2 branes. We obtain our partition function by performing the radial quantization of the Coulomb Branches of these theories and rederive the same formula from the quantization of supers...
متن کاملDual giant gravitons in AdSm × Y (Sasaki-Einstein)
We consider BPS motion of dual giant gravitons on AdS5 × Y 5 where Y 5 represents a five-dimensional Sasaki-Einstein manifold. We find that the phase space for the BPS dual giant gravitons is symplectically isomorphic to the Calabi-Yau cone over Y 5, with the Kähler form identified with the symplectic form. The quantization of the dual giants therefore coincides with the Kähler quantization of ...
متن کاملSemiclassical Quantization of the Giant Magnon
Solitons in field theory provide a window into regimes not directly accessible by the fundamental perturbative degrees of freedom. Motivated by interest in the worldsheet S-matrix of string theory in AdS5×S in the limit of infinite worldsheet volume we consider the semiclassical quantization of a particular soliton of this theory: the Hofman-Maldacena ‘giant magnon’ spinning string. We obtain e...
