Phys. Rev. D 76, 067701 (2007) [4 pages]Path-integral formulation of pseudo-Hermitian quantum mechanics and the role of the metric operatorReceived 7 June 2007; published 13 September 2007 We provide a careful analysis of the generating functional in the path-integral formulation of pseudo-Hermitian and in particular PT-symmetric quantum mechanics and show how the metric operator enters the expression for the generating functional. © 2007 The American Physical Society URL:
