SEMICLASSICAL vs. EXACT SOLUTIONS OF CHARGED BLACK HOLE IN FOUR DIMENSIONS AND EXACT O(d, d) DUALITY

We derive a charged black hole solution in four dimensions described by SL(2, R)× SU(2)×U(1)/U(1)2 WZW coset model. Using the algebraic Hamiltonian method we calculate the corresponding solution that is exact to all orders in 1 k . It is shown that unlike the 2D black hole, the singularity remains also in the exact solution, and moreover, in some range of the gauge parameter the space-time does...

Exact primordial black strings in four dimensions.

A solution of effective string theory in four dimensions is presented which admits interpretation of a rotating black cosmic string. It is constructed by tensoring the three dimensional black hole, extended with the Kalb-Ramond axion, with a flat direction. The physical interpretation of the solution is discussed, with special attention on the axion, which is found to play a role very similar t...

Exact Black String Solutions in Three Dimensions

A family of exact conformal field theories is constructed which describe charged black strings in three dimensions. Unlike previous charged black hole or extended black hole solutions in string theory, the low energy spacetime metric has a regular inner horizon (in addition to the event horizon) and a timelike singularity. As the charge to mass ratio approaches unity, the event horizon remains ...

Integrability of Some Charged Rotating Supergravity Black Hole Solutions in Four and Five Dimensions

We study the integrability of geodesic flow in the background of some recently discovered charged rotating solutions of supergravity in four and five dimensions. Specifically, we work with the gauged multicharge Taub-NUT-Kerr-(Anti) de Sitter metric in four dimensions, and the U(1)3 gauged charged-Kerr-(Anti) de Sitter black hole solution of N = 2 supergravity in five dimensions. We explicitly ...

Exact superpotentials in four dimensions.

Supersymmetric gauge theories in four dimensions can display interesting non-perturbative phenomena. Although the superpotential dynamically generated by these phenomena can be highly nontrivial, it can often be exactly determined. We discuss some general techniques for analyzing the Wilsonian superpotential and demonstrate them with simple but non-trivial examples.
