Spatial superposition for a two-dimensional matter-wave interferometer in an inverted harmonic potential with gyroscopic rotational stability
This study develops a mathematical model to create macroscopic quantum spatial superpositions using a Stern-Gerlach Interferometer (SGI) scheme within an inverted harmonic potential (IHP). By modeling the 2D motion of a nanodiamond, the research demonstrates how applying specific linear and non-linear magnetic fields can generate complex wave-packet evolutions. This model is vital for testing quantum mechanics at larger scales.
