Corrected Hawking radiation from a charged rotating black string

Using the Damour–Ruffini method, Hawking radiation from a four-dimensional charged rotating black string in asymptotically anti-de Sitter space–time is investigated. When energy, angular momentum, charge conservations, and the particles’ back-reaction to the space–time are taken into account, the exact emission spectrum near the horizon is calculated. The horizon is not spherical, but can be toroidal and cylindrical. Our results indicate that the spectrum is not purely thermal, which may be consistent with an underlying unitary theory. Moreover, it is a possible mechanism to explain the information loss paradox.
