  The Schwarzschild black two-brane in four-dimensional anti-de Sitter space is
dual to a finite temperature state in three-dimensional conformal field theory.
We show that the solution acquires a nonzero angular momentum density when a
gravitational Chern-Simons coupling is turned on in the bulk, even though the
solution is not modified. A similar phenomenon is found for the
Reissner-Nordstrom black two-brane with axionic coupling to the gauge field. We
discuss interpretation of this phenomenon from the point of view of the
boundary three-dimensional conformal field theory.
