Thomas Galley: Principle based approaches to the nature of gravity - RQI Circuit Vienna 2023

Title: Principle based approaches to the study of the nature of the gravitational field
Abstract: In this talk I will outline the difference between a 'principles' approach to physics as opposed to a 'model based' approach. I will show how one can apply the principle based approach to the current discussions around table top tests of the quantum nature of the gravitational field, by using the framework of general probabilistic theories. Finally I will argue that principle based approaches are especially relevant to interdisciplinary research areas such as this one, and outline some open research questions.
Talk delivered at IQOQI Vienna on November 10th 2023.
