We deal with the reversible dynamics of coupled quantum and classical systems. Based on a recent proposal by the authors, we exploit the theory of hybrid quantum–classical wavefunctions to devise a closure model for the coupled dynamics in which both the quantum density matrix and the classical Liouville distribution retain their initial positive sign. In this way, the evolution allows identifying a classical and a quantum state in interaction at all times, thereby addressing a series of… 
Measurement of a quantum system with a classical apparatus using ensembles on configuration space
Finding a physically consistent approach to modelling interactions between classical and quantum systems is a highly nontrivial task. While many proposals based on various mathematical formalisms

Koopman wavefunctions and classical–quantum correlation dynamics
TLDR
This paper addresses the long-standing problem of formulating a dynamical theory of classical–quantum coupling using the exactly solvable model of a degenerate two-level quantum system coupled to a classical harmonic oscillator.
From Quantum Hydrodynamics to Koopman Wavefunctions II
TLDR
This work forms a Hamiltonian model for hybrid quantum-classical systems by writing the KvH wave equation for two classical particles and applying canonical quantization to one of them and presents a class of hybrid Hamiltonians whose flow preserves the sign of the classical density.

TLDR
The results of studies of proton transfer in condensed phase and reactive dynamics in a dissipative environment are presented to illustrate applications of the quantum-classical Liouville formalism.

From Quantum Hydrodynamics to Koopman Wavefunctions I
TLDR
Upon applying the Madelung transform from quantum hydrodynamics in the new context, it is shown how the Koopman wavefunction picture is insufficient to reproduce arbitrary classical distributions, but this problem is entirely overcome by resorting to von Neumann operators.
