Microphysics - Greg Egan

"In quantum mechanics, every particle has a phase: a kind of abstract vector which rotates like the hand of a clock, turning at a constant rate in the particle's reference frame. In flat spacetime, a straight worldline represents motion with a constant velocity, and any detour from this causes time dilation, shortening the time — and hence reducing the phase shift — that a particle experiences as it travels between two given points."
