Resumo: No experiment today provides evidence that gravity requires a quantum description. Two types of table-top searches have been suggested to provide answers: experiments that test low-energy consequences of quantum theories of gravity, and experiments that directly probe the phenomenology of superposition states of gravitational source masses (in the spirit of a quantum-Cavendish experiment). The latter requires to bridge the gap between two different realms: precision measurements of gravity with microscopic source masses (currently 10^21 atoms) and quantum state preparations of massive solid state objects (currently 10^9 atoms). I will review the current status in the lab and the challenges to be overcome for future experiments.
Sobre o palestrante: PI Aspelmeyer leads the Quantum Optomechanics group at the University of Vienna, Austria. His expertise is in quantum optical control of micro-and nanomechanics. His research interests are quantum entanglement, quantum optics and gravitational quantum physics.
PI Aspelmeyer and his expert colleagues will work in collaboration with the Centre to increase international research networks.
Palavras-chaves: Superposition of gravitational source masses; Superpositions of solid state objects, gravity with microscopic source masses.
