Gravitational Waves from Rotating Black Strings
In the Randall-Sundrum two-brane model (RS1), a Kerr black hole on the brane can be naturally identified with a section of rotating black string. To estimate KaluzaKlein (KK) corrections on gravitational waves emitted by perturbed rotating black strings, we give the effective Teukolsky equation on the brane which is separable equation and hence numerically manageable. In this process, we derive...
متن کاملRigidly Rotating Strings in Stationary Axisymmetric Spacetimes
In this paper we study a motion of a rigidly rotating Nambu-Goto test string in a stationary axisymmetric background spacetime. As special examples we consider rigid rotation of strings in a flat spacetime, where explicit analytic solutions can be obtained, and in the Kerr spacetime.
متن کاملRotating Strings in Confining AdS/CFT Backgrounds
We study semiclassical rotating strings in AdS/CFT backgrounds that exhibit both confinement and finite-size effects. The energy versus spin dispersion relation for short strings is the expected Regge trajectory behaviour, with the same string tension that is measured by the Wilson loop. Long strings probe the interplay between confinement and finite-size effects. In particular, the dispersion ...
متن کاملGeometric cross sections of rotating strings and black holes
We study the production cross section of a highly excited string with fixed angular momentum from an ultra-high energy collision of two light strings. We find that the cross section exhibits geometric behavior in a certain region of angularmomentum/impact-parameter space. This geometric behavior is common to the differential cross sections of a black hole production with fixed angular momentum ...
متن کاملQuantum fluctuations of rotating strings in AdS 5 × S 5
We discuss quantum fluctuations of a class of rotating strings in AdS5×S. In particular, we develop a systematic method to compute the one-loop sigma-model effective actions in closed forms as expansions for large spins. As examples, we explicitly evaluate the leading terms for the constant radii strings in the SO(6) sector with two equal spins, the SU(2) sector, and the SL(2) sector. We also o...
