Non-Abelian Giant Gravitons
We argue that the giant graviton configurations known from the literature have a complementary, microscopical description in terms of multiple gravitational waves undergoing a dielectric (or magnetic moment) effect. We present a non-Abelian effective action for these gravitational waves with dielectric couplings and show that stable dielectric solutions exist. These solutions agree in the large...
متن کاملGiant Hedge-Hogs: Spikes on Giant Gravitons
We consider giant gravitons on the maximally supersymmetric plane-wave background of type IIB string theory. Fixing the light-cone gauge, we deduce the low energy effective light-cone Hamiltonian of the three-sphere giant graviton. At first order, this is a U(1) gauge theory on R × S. We place sources in this effective gauge theory. Although nonvanishing net electric charge configurations are d...
متن کاملCounting Giant Gravitons in AdS3
We quantize the set of all quarter BPS brane probe solutions in global AdS3 × S × T /K3 found in [1]. We show that, generically, these solutions give rise to states in discrete representations of the SL(2, R) WZW model on AdS3. Our procedure provides us with a detailed description of the low energy 1 4 and 1 2 BPS sectors of string theory on this background. The 1 4 BPS partition function jumps...
متن کاملVibration modes of giant gravitons
We examine the spectrum of small vibrations of giant gravitons, when the gravitons expand in the anti-de-Sitter space and when they expand on the sphere. For any given angular harmonic, the modes are found to have frequencies related to the curvature length scale of the background; these frequencies are independent of radius (and hence angular momentum) of the brane itself. This implies that th...
متن کاملSemiclassical Quantization of Giant Gravitons
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 . Th...
