- Theory Seminar (High Energy/Cosmology)
- Extensions of a scale separation AdS$_4$ solution and their mass spectrum.
- Time: 12:00 pm - 1:00 pm
- Place: 5280 Chamberlin Hall
- Speaker: Georgios Tringas , Annecy, LAPTH
- Abstract: In this talk we will discuss two extensions of the so-called DGKT solution, a 4d scale-separated anti-de Sitter (AdS) solution obtained as a compactification on a 6d torus orbifold. Each extension consists in a specific large n expansion beyond the DGKT solution, where n is the unbounded F4-flux parameter. One of the extensions considered generalizes the known warped, partially localized solution. We analyse the two extensions in 10d massive type IIA supergravity as well as in a 4d effective theory, using a general warped compactification formalism. The main new correction to DGKT that we get is one from F4, the other fluxes being constrained by flux quantization. In each extension, one would expect corrections to the mass spectrum, before reaching contributions from alpha-prime corrections. However the mass spectrum turns out to be robust and conformal dimensions remain unchanged.

- GREAT IDEAS DEI Reading Group
- GREAT IDEAS Coffee Hour
- Time: 12:00 pm - 1:00 pm
- Place: Sterling B343
- Abstract: We will be discussing the article "Accelerating and scaling mentoring strategies to build infrastructure that supports underrepresented groups in STEM" by Adams et al (paper pdf). We will also be going over a brief summary at the beginning of the hour and welcome attendees who have not had a chance to read the article.
GREAT IDEAS stands for Group for Reading, Educating, And Talking about Inclusion, Diversity, Equity, & Advocacy in Science. It is a multimedia reading group dedicated to amplifying the experiences of underrepresented groups in science and academia in order to become better advocates for our peers. GREAT IDEAS is open to everyone (students/ faculty/ staff/ etc), and all are welcome and encouraged to engage with the material and contribute to the discussions. To keep a welcoming and safe environment for everyone, we ask that everyone understand and adhere to our community guidelines for the discussions. - Host: GMaWiP (contact Faizah with questions)
