Improved Stability for Pulsating Multi-Spin String Solitons
A. Khan, A. L. Larsen
We derive and analyse, analytically and numerically, the equations for perturbations around the pulsating two-spin string soliton in AdS(5) x S(5).We show that the pulsation in S(5…
Novel Explicit Multi Spin String Solitons in AdS(5)
A. L. Larsen, A. Khan
We find new explicit solutions describing closed strings spinning with equal angular momentum in two independent planes in AdS(5). These are 2N-folded strings in the radial directi…
Spinning Pulsating String Solitons in AdS_5 x S^5
A. Khan, A. L. Larsen
We point out the existence of some simple string solitons in AdS_5 x S^5, which at the same time are spinning in AdS_5 and pulsating in S^5, or vice-versa. This introduces an addit…
Open String Fluctuations in AdS with and without Torsion
A. L. Larsen, M. A. Lomholt
The equations of motion and boundary conditions for the fluctuations around a classical open string, in a curved space-time with torsion, are considered in compact and world-sheet…
Cosmic Strings and Black Holes
A. L. Larsen
In the first part of this talk, I consider some exact string solutions in curved spacetimes. In curved spacetimes with a Killing vector (timelike or spacelike), the string equation…
