| Speaker: | Vincent Rivasseau (Orsay, LPT) |
| Abstract: | The talk will review the current status of the tensor track, introduced about seven years ago as a program to explore quantum gravity with modern random tensor theory. Tensor models provide a sum over geometries pondered by a discretized version of the Einstein-Hilbert action. They were more recently connected to conformal field theory and toy models of quantum black holes. However their associated particle content is still unknown; it has been suggested that it could correspond to new families of higher spin theories. |

| Wave function collapse, gravity and cosmology |
| Speaker: | Prof. Angelo Bassi (Università degli Studi di Trieste) |
| Abstract: | To make quantum theory consistent, models of spontaneous wave function collapse (collapse models) propose to modify the Schrödinger equation by including nonlinear and stochastic terms, which describe the collapse of the wave function in space. These spontaneous collapses are “rare” for microscopic systems, hence their quantum properties are left almost unaltered. At the same time, since the collapses add coherently in composite systems, macroscopic spatial superpositions of macro-objects are rapidly suppressed. I will review the main features of collapse models, and will present an update of the most promising ways of testing them in interferometric and non-interferometric experiments, showing the current lower and upper bounds on their parameters. Next, I will discuss ideas ... [full abstract available here: https://indico.smi.oeaw.ac.at/event/302/] |

| A nonrelativistic limit of AdS perturbations |
| Speaker: | Piotr Bizon (Kraków) |
| Abstract: | I will discuss dynamics of small amplitude solutions of the Schroedinger-Newton system with an external harmonic potential. This system arises in a nonrelativistic limit from the Einstein-Klein-Gordon equations with a negative cosmological constant. The main goal is to understand the resonant transfer of energy to small spatial scales. |
