Day 4 of #ICOLS2023 !
Today we heard a lot of about the different applications of highly precise #AtomicClocks (and #MolecularClocks) - for detecting height differences via the gravitational redshift, for testing the fundamental principles of #GeneralRelativity or for detecting/excluding #DarkMatter candidates!
There were also very nice theory contributions explaining the ideas for new #physics and showing us what we could see if only our experiments measured at a higher precision!

Oggi insieme a Sebastiano Pilati e Marco G. Tarallo presento una ricerca con metodi quantum Monte Carlo sul ruolo delle interazioni intraspecie in gas di Fermi ultrafreddi.

Today my collaborators Sebastiano Pilati and Marco G. Tarallo and I are finally submitting our quantum Monte Carlo investigation of the role of intra-species interactions in many-body Fermi gases. Time for some deserved vacation... https://arxiv.org/abs/2212.09150

How does Britain know what #time it is?

A no-math explanation on how optical combs work and how they give us mind-bogglingly accurate atomic clocks. Pretty brain-twisting to see how quantum physics is at the heart of it. TL;DR, it's all due to optical beat frequencies and this still applies when its individual photons interacting to produce the beats.
