摘要
We compute a Chern-Simons term induced by the fermions on noncommutative torus interacting with two U(1) gauge fields. For rational noncommutativity \theta \propto P/Q we find a new mixed term in the action which involves only those fields which are (2\pi)/Q periodic, like the fields in a crystal with Q^2 nodes.
