heal.abstract	We demonstrate that a chiral particle-hole condensate is always induced by a number-conserving ground state of nonzero angular momentum in the presence of a magnetic field. The magnetic interaction originates from the coupling with the intrinsic orbital moment of the chiral state when the field is applied perpendicularly to the plane. According to our numerical results, the induction mechanism is practically temperature independent, providing robustness to these states up to high temperatures. This opens the door for manipulating the anomalous Hall response resulting from this intricate class of states for technological applications while it also suggests that chiral particle-hole condensates may be hidden in various complex materials. © 2009 The American Physical Society.	en
