Title: Witnessing Quantum gravity in a laboratory via miniaturist quantum accelerator
Abstract: Unveiling
the nature of spacetime remains one of the final frontiers of modern
theoretical physics. I will discuss how to witness the quantum nature of
gravity in a table-top experiment by creating the right witness
involving the two neutral masses (spin embedded) undergoing through the
Stern-Gerlach apparatus. I will discuss various challenges involved in
pursuing the dream of witnessing graviton and the critical challenges.
There are many challenges to be met and I will discuss the important
ones: (1) To
create a macroscopic quantum superposition of heavy masses via the
Stern-Gerlach setup while controlling the stray gravitational
acceleration and the gravity gradient noise, (2) Precise constraints on the magnetic field/current such that various electromagnetic interactions are under control, (3) Vacuum dominated Casimir effect which will create the main background for the experiment, (4) Constraints on vacuum and temperatures, (5) Feasibility of the experiment in a drop-tower, (6) The material properties and patch potentials. I
will briefly discuss time scales for realising such an accelerator
which will witness for the first time the graviton in a terrestrial
laboratory.
