Recently\, the study of gravitating q uantum systems\, for instance a massive quantum system prepared in a quant um superposition of positions and sourcing a gravitational field\, has att racted a lot of attention: experiments are working towards realising such a scenario in the laboratory\, and measuring the gravitational field assoc iated to a quantum source is expected to give some information about quant um aspects of gravity. However\, there are still open questions concerning the precise conclusions that these experiments could draw on the nature o f gravity\, such as whether experiments in this regime will be able to tes t more than the Newtonian part of the gravitational field.\n\nIn this talk \, I will show that a static mass in a quantum state gives rise to effects that cannot be reproduced using the Newton potential nor with a known cla ssical model of gravity. These effects can in principle be measured by per forming an interference experiment\, and are independent of graviton emiss ion. Identifying stronger quantum aspects of gravity than those reproducib le with the Newton potential is crucial to prove the nonclassicality of th e gravitational field and to plan a new generation of experiments testing quantum aspects of gravity in a broader sense than what proposed so far.\n LOCATION:https://researchseminars.org/talk/3cqfs/13/ END:VEVENT END:VCALENDAR
