Consistency with quantum gravity and black hole physics puts
significant constraints on low-energy effective field theories. In fact,
most EFT’s do not satisfy these criteria, and are said to be in the
“Swampland”. Most Swampland constraints remain conjectural, supported
mainly by a plethora of stringy examples. In this talk I will discuss a
rigorous example of a Swampland...

It is known that there are AdS vacua obtained from compactifying the Standard Model to 2 or 3 dimensions. However, using the Weak Gravity Conjecture, it has been recently argued by Ooguri and Vafa that non supersymmetric stable AdS vacua are incompatible with quantum gravity. By requiring the absence of these vacua we can put constraints on the SM spectra, obtaining a lower bound for the...

I will discuss how a better understanding of non-linearly realized supergravity has led to interesting progress and an improved understanding of dS vacua and inflation in supergravity and string flux compactifications.

We develop a new class of supergravity cosmological models where inflation is induced by terms in the Kähler potential which mix a nilpotent superfield S with a chiral sector Φ. As the new terms are non-(anti)holomorphic, and hence cannot be removed by a Kähler transformation, these models are intrinsically Kähler potential driven. Such terms could arise for example due to a backreaction of an...

Using a 10D lift of non-perturbative volume stabilization in type IIB string theory we find that the simplest KKLT vacua cannot be uplifted to de Sitter upon inclusion of SUSY breaking sources like anti-branes. Rather, the uplift is flattened due to stronger back-reaction on the volume modulus than has previously been anticipated such that the resulting vacua are always AdS. We find that this...
