Fluxes of Higher-spin Currents and Hawking Radiations from Charged Black Holes

Understand

This is an extended version of the previous paper (hep-th/0701272).

• Quantum fields near horizons can be described in terms of an infinite set of two-dimensional conformal fields.
• We first generalize the method of Christensen and Fulling to charged black holes to derive fluxes of energy and charge.
• These fluxes can be obtained by employing a conformal field theory technique.
