SUMMARY:Bubble instability of mIIA on AdS_4 x S^6
DESCRIPTION:Speaker: Pieter Bomans\, Princeton \nTitle: Bubble instability of mIIA on AdS_4 x S^6 \nAbstract: Recently\, a set of non-supersymmetric AdS_4 vacua of massive type IIA string theory has been constructed. These vacua are perturbatively stable with respect to the full KK spectrum of type mIIA supergravity and furthermore\, they are stable against a variety of non-perturbative decay channels. Hence\, at this point\, they represent a serious challenge to the AdS swampland conjecture. In my talk\, I will review in detail the construction of these vacua as well as introduce a new decay channel\, ultimately sealing their fate as being unstable.

SUMMARY:11/15/2021 – Swampland Seminar
DESCRIPTION:This week’s seminar will be an open mic discussion which will be led by Nima Arkani-Hamed (IAS)\, and by Gary Shiu (UW-Madison)\, and the topic will be “Swampland constraints\, Unitarity and Causality”. They will start with a brief introduction sharing their thoughts about the topic and moderate a discussion afterwards.

SUMMARY:Taming the Landscape
DESCRIPTION:Abstract: In this talk I will introduce a generalized notion of finiteness that provides a structural principle for the set of effective theories that can be consistently coupled to quantum gravity. More concretely\, I will propose a ‘tameness conjecture’ that states that all scalar field spaces and coupling functions that appear in such an effective theory must be definable in an o-minimal structure. The fascinating field of tame geometry has seen much recent progress and I will argue that the results can be used to support the above swampland conjecture. The strongest evidence arises from a new finiteness theorem for the flux landscape which is shown using the tameness of the period map.

SUMMARY:Scale separated AdS vacua?
DESCRIPTION:Abstract: In this talk I will review massive type IIA flux compactifications that seem to give rise to infinite families of supersymmetric 4d AdS vacua. These vacua provide an interesting testing ground for the swampland program. After reviewing potential shortcomings of this setup\, I will discuss recent progress on overcoming them and getting a better understanding of these solutions.
