Unitary equivalence of Schr\"odinger and Heisenberg pictures survives in nonlinear quantum mechanics

The equivalence of Schr\"odinger and Heisenberg pictures is often thought to break down in nonlinear quantum mechanics due to the absence of a state-independent unitary propagator. We show that for Hamiltonians depending on the state through instantaneous expectation values, the equivalence is preserved. While the unit...
