de Sitter no-go's for Riemann-flat manifolds and a link to semidefinite optimisation
Bruno Valeixo Bento, Miguel Montero
We establish a no-go theorem in the context of string and M-theory flux compactifications on Riemann-Flat manifolds with Casimir energy. Specifically, we show that no dS minimum ex…
EFT & Species Scale: Friends or foes?
Bruno Valeixo Bento, João F. Melo
Recently the notion that quantum gravity effects could manifest at scales much lower than the Planck scale has seen an intense Swamplandish revival. Dozens of works have explored h…
Gravity at the Tip of the Throat
Bruno Valeixo Bento, Dibya Chakraborty, Susha Parameswaran +1
We study the gravitational signatures that arise from compactifying Type IIB supergravity on a compact space containing a Klebanov-Strassler warped throat. After reviewing the dime…
If time had no beginning
Bruno Valeixo Bento, Stav Zalel
General Relativity traces the evolution of our Universe back to a Big Bang singularity. To probe physics before the singularity -- if indeed there is a ``before'' -- we must turn t…
If time had no beginning: growth dynamics for past-infinite causal sets
Bruno Valeixo Bento, Fay Dowker, Stav Zalel
We explore whether the growth dynamics paradigm of Causal Set Theory is compatible with past-infinite causal sets. We modify the Classical Sequential Growth dynamics of Rideout and…
A New de Sitter Solution with a Weakly Warped Deformed Conifold
Bruno Valeixo Bento, Dibya Chakraborty, Susha L. Parameswaran +1
We revisit moduli stabilisation for type IIB flux compactifications that include a warped throat region corresponding to a warped deformed conifold, with an anti-D3-brane sitting a…
