Dynamics of Anti-de Sitter Domain Walls
We study solutions corresponding to moving domain walls in the RandallSundrum universe. The bulk geometry is given by patching together black hole solutions in AdS5, and the motion of the wall is determined from the junction equations. Observers on the wall interpret the motion as cosmological expansion or contraction. We describe the possible wall trajectories, and examine the consequences for...
متن کاملDomain Walls from Anti - de Sitter Spacetime
We examine (D − 2)-brane solutions in supergravities, showing that they fall into four categories depending on the details of the dilaton coupling. In general they describe domain walls, although in one of the four categories the metric describes anti-de Sitter spacetime. We study this case, and its S 1 dimensional reduction to a more conventional domain wall in detail, focussing in particular ...
متن کاملAnti-de Sitter D-brane dynamics
We study the anti-de Sitter D-brane dynamics in Hamiltonian formulation. By exploiting the existence of certain conserved charges, we solve the equation of motion for a D1-brane in the AdS3 background and find the space-time dependent solutions. We further study the dynamics by mapping the problem to that of the open string tachyon, and examine the time dependent solutions in some detail.
متن کاملSuper algebra and Harmonic Oscillator in Anti de Sitter space
The harmonic oscillator in anti de Sitter space(AdS) is discussed. We consider the harmonic oscillator potential and then time independent Schrodinger equation in AdS space. Then we apply the supersymmetric Quantum Mechanics approach to solve our differential equation. In this paper we have solved Schrodinger equation for harmonic oscillator in AdS spacetime by supersymmetry approach. The shape...
متن کاملAnti-de Sitter Fragmentation
Some general aspects of the AdS2/CFT1 correspondence, previously discussed in hep-th/9812073, are summarized. The majority of this summary is devoted to the question of where the CFT1 should live. Almost as a byproduct, the decay—or fragmentation—of AdS2 is also discussed. As is hopefully symptomatic of the number of contributions in the Cargese ’99 proceedings devoted to this conjecture, the A...
