Spinning -model solitons in Anti-de Sitter space
B. Harms, A. Stern
We obtain numerical solutions for rotating topological solitons of the nonlinear -model in three-dimensional Anti-de Sitter space. Two types of solutions, and , are fo…
Three dimensional gravity from ISO(2,1) coset models
R. Casadio, B. Harms
Starting from a WZWN action in the ISO(2,1) Poincare' group which describes a bosonized spinning string in 2+1 Minkowski space-time, we show that a sequence of non-trivial compacti…
New perturbative solutions of the Kerr-Newman dilatonic black hole field equations
R. Casadio, B. Harms, Y. Leblanc +1
This work describes new perturbative solutions to the classical, four-dimensional Kerr--Newman dilaton black hole field equations. Our solutions do not require the black hole to be…
Bosonic Description of Spinning Strings in Dimensions
B. Harms, A. Stern
We write down a general action principle for spinning strings in 2+1 dimensional space-time without introducing Grassmann variables. The action is written solely in terms of coordi…
