Phys. Rev. D 66, 044007 (2002) [5 pages]Is Einstein’s equivalence principle valid for a quantum particle?Received 3 December 2001; published 19 August 2002 Einstein’s equivalence principle in classical physics is a rule stating that the effect of gravitation is locally equivalent to the acceleration of an observer. The principle determines the motion of test particles uniquely (modulo very broad general assumptions). We show that the same principle applied to a quantum particle described by a wave function on a Newtonian gravitational background determines its motion with a similar degree of uniqueness. © 2002 The American Physical Society URL:
