Repulsive Gravitational Force as a Witness of the Quantum Nature of Gravity
Pablo L. Saldanha, Chiara Marletto, Vlatko Vedral
We show that a single spatially superposed 'source' mass acting on a 'probe' matter wavepacket can reveal the quantum nature of the gravitational field. For this we use a specific…
Topology of the Aharonov-Bohm effect in different reference frames
Hiram S. M. Rodrigues, Katson W. O. Arévola, Pablo L. Saldanha
Recent works showed that the Aharonov-Bohm (AB) phase difference for a quantum charged particle can be written in terms of electric and magnetic fluxes in a spacetime surface whose…
Topological schemes in spacetime for the electrodynamic Aharonov-Bohm effect
Pablo L. Saldanha, Herman Batelaan
We consider different schemes for the electrodynamic Aharonov-Bohm (AB) effect introduced in Ref. [Phys. Rev. A , 062218 (2023)], exploring the phenomenon to enhance…
Quantum Interference of Force with Entangled Photons
Gabriela S. Militani, Artur Matoso, Denise F. Ãvila +4
In this work we experimentally demonstrate the quantum interference of force effect using pairs of entangled photons. Although photons are massless particles, they have linear mome…
