Action on the Sphere: An Interfering Mean-Field Propagator for the Bose-Hubbard Dimer
The Interfering Mean-Field Propagator (IMF) is a semiclassical method approximating complex many-particle dynamics in systems like the Bose-Hubbard dimer. It propagates uncoupled SU(2) coherent states, tracking individual phases from mean-field trajectories. This approach accurately captures quantum interference effects, specifically breakdown and revival dynamics, extending beyond simple mean-field descriptions.
