Bypassing no-go theorems on mixed classical-quantum systems: the (counter)example of hybrid van Hove theory
Marcel Reginatto, Andrés Darío Bermúdez Manjarres, Sebastian Ulbricht
Motivated by models of mixed quantum-classical hybrid theories, we consider the representation of classical observables as Hilbert-space operators based on van Hove's unitary repre…
Entanglement of quantum systems via a classical mediator in hybrid van Hove theory
Sebastian Ulbricht, Andrés Darío Bermúdez Manjarres, Marcel Reginatto
It is a matter of ongoing discussion whether quantum states can become entangled while only interacting via a classical mediator. This lively debate is deeply interwoven with the q…
Classical and mixed classical-quantum systems from van Hove's unitary representation of contact transformations
Marcel Reginatto, Andrés Darío Bermúdez Manjarres, Sebastian Ulbricht
Descriptions of classical mechanics in Hilbert space go back to the work of Koopman and von Neumann in the 1930s. Decades later, van Hove derived a unitary representation of the gr…
Classical dynamics from a unitary representation of the Galilei group
Andres D. Bermudez Manjarres, Marek Nowakowski, Davide Batic
We give a formulation of classical mechanics in the language of operators acting on a Hilbert space. The formulation given comes from a unitary irreducible representation of the Ga…
