On Using Controllable Mass Objects to Induce Linear Motion on Staionary Systems

In a Gedanken experiment, we previously demonstrated that, by carefully changing the mass of an object undergoing 1D harmonic motion, an otherwise stationary system can undergo induced linear motion over the course of a complete harmonic cycle. Here we expand upon this result and consider the effects of isolated versus coupled mass exchange between two controllable mass objects in a two-mass spring system.  Additionally, we analyze the effects of locally changing an object's mass and address necessary conditions for setting up a quantum system that incorporates vacuum symmetry breaking to induce bulk motion in harmonic quantum system.
