The Galilean covariance of nonrelativistic quantum mechanics is genera
lized to acceleration transformations. Projective representations of t
he group of acceleration transformations are constructed and the resul
ting unitary operators are shown to implement arbitrary accelerations.
These unitary operators are used to modify the time-dependent Schrodi
nger equation and produce the quantum mechanical analog of fictitious
forces. The relationship of accelerating systems to gravitational forc
es is discussed, as well as the effects of accelerations on the intern
al structure of quantum mechanical systems. (C) 1997 Academic Press.
