Equivalence of two approaches for quantum-classical hybrid systems.
We discuss two approaches that are frequently used to describe quantum-classical hybrid system. One is the well-known mean-field theory and the other adopts a set of hybrid brackets which is a mixture of quantum commutators and classical Poisson brackets. We prove that these two approaches are equivalent.
