Talk by Lin-Qing Chen: The Schrödinger wave functionals of Coulomb and Newtonian fields sourced by quantum matter

This work is in collaboration with F. Giacomini and C. Rovelli (in preparation).

The speaker will present a derivation of the quantum state wave functionals of electromagnetism and linearized gravitational fields sourced by quantum matter in the Newtonian limit, possibly in superposition. This work is in collaboration with F. Giacomini and C. Rovelli (in preparation). The results provide a complementary perspective for the mechanism of the gravity-mediated entanglement in the laboratory. For the future, it could open up other novel possibilities of testing nonclassical features of gravity.

If time permits, Lin-Qing Chen would also like to discuss a preliminary on-going work of understanding quantum reference frames for gauge fields and the relationship with "edge modes" from the quantum state of the electromagnetism field.
