Abstract
We propose a lattice action for the overlap Dirac matrix with nonzero chemical potential which is shown to preserve the chiral invariance on the lattice exactly. We further demonstrate it to arise in the domain wall formalism by letting the chemical potential count only the physically relevant wall modes.
