All the videos from the FCQG meeting of January 2020 are now available on our YouTube channel: https://www.youtube.com/playlist?list=PLVzK6UpZmNq3ddJJvX70VjK-g615qLT7y. Enjoy!
We just posted the second set of talks from the January meeting onto our YouTube channel: https://www.youtube.com/playlist?list=PLVzK6UpZmNq3ddJJvX70VjK-g615qLT7y
Ivan Agullo, Daniel Sudarsky, Elias Okon, Richard Dawid, Juliusz Doboszewski, and Alexei Starobinsky.
We are very happy to announce the first set of talks from the conference that we co-organized in January 2020, held at NYU Abu Dhabi. So far talks by: Daniele Oriti, Baptiste Le Bihan, Béatrice Bonga, James Read, Chris Smeenk, Robert Brandenberger, and Mairi Sakellariadou, with more to follow soon. Go to our YouTube channel.
Some of the lectures in the (Virtual) Midwest Summer School in Philosophy of Physics may be of interest to the followers of this blog: https://sites.google.com/view/msspp2020
Regrettably, we cannot take any more participants, but everyone (internet gods willing) can follow on YouTube (and later watch the lectures).
We’re happy to say that we have posted another chapter of our book – available under the ‘Publications &c’ tab (or here). Watch this space for more over the summer (though unfortunately we are not permitted to post the whole thing).
To the many of you who have asked ‘when our book would be finished’, I am happy to say that we have started posting draft chapters on the website! The book is title Out of Nowhere: The Emergence of Spacetime in Quantum Theories of Gravity, and so far chapters on causal set theory and string theory are available. Follow the ‘Publications &c’ tab, or click here. More chapters as they are finished. Enjoy!
We are very happy to announce that the first of a pair of volumes of papers from our project has been published! Many of the papers are from talks we haver organized or our annual essay contest. The full table of contents is here. You can access it online today, and the print version will follow soon (it already exists, but has not reached the stores yet). Many, many thanks to our contributors!
• Wednesday 6 May 2020 at UIC at 09:30 (14:30 UTC) – Andrew Geraci (Northwestern): Searching for “Fifth-forces”, Dark Matter, and Quantum Gravity in the Lab
We normally think of large accelerators and massive detectors when we consider the frontiers of elementary particle physics, pushing to understand the universe at higher and higher energy scales. However, several tabletop low-energy experiments are positioned to discover a wide range of new physics beyond the Standard model of particle physics, where feeble interactions require precision measurements rather than high energies. In high vacuum, optically-levitated dielectric nanospheres achieve excellent decoupling from their environment, making force sensing at the zeptonewton level (10-21 N) achievable. In this talk I will describe our progress towards using these sensors for tests of the Newtonian gravitational inverse square law at micron length scales. Optically levitated dielectric objects and show promise for a variety of other applications, including searches for gravitational waves and Dark Matter. Cooling these objects into the quantum regime of their motion paves the way for tests of quantum coherence in macroscopic objects and tests of whether gravity can destroy such coherence. Looking forward, these systems may enable us to examine the role that gravity plays in quantum mechanical entanglement.
