# Staff members with discipline Physics, Particles & Fields

Academia develops at the interface of different fields. This is one reason why the University of Groningen is home to a wide range of fields, each with a great number of subject specialists. The overview below, which is based on a standard categorization of fields, will help you find the right expert for each field. If you cannot find the expert you are looking for in this list, try searching via a related field or faculty; you may find him or her there.

_{(1)}_{Tests of Quantum Gravity via Quantum Entanglement in a laboratory. I am one of the key proponents of this idea, along with my key collaborators. }

_{"Spin entanglement witness for quantum gravity}

_{." We are aiming to design the tiniest (micron-size nano-crystals) particle accelerator to create the Schrödinger Cat state in a laboratory to test the quantum nature of spacetime. In particular, this will lead to the very first demonstration that the gravitational interaction with the matter is quantum in nature. In the context of a perturbative quantum gravity this would surmount to understand the properties of spin-2 nature of the graviton "}

_{", and "}

_{Locality and entanglement in table-top testing of the quantum nature of linearized gravity}

_{".}_{(2)}_{To test Quantum Gravity induced Entanglement of Masses (known as QGEM protocol), we will need to create a macroscopic quantum superposition with heavy masses, large superposition, and a long coherence timescale. Our group is closely working with experimental groups to realize such a protocol in a laboratory: "}
