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…
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…
Inflationary implications of the Covariant Entropy Bound and the Swampland de Sitter Conjectures
Dibya Chakraborty, Cesar Damian, Alberto Gonzalez Bernal +1
We present a proposal to relate the de Sitter Conjecture (dSC) to the Covariant Entropy Bound (CEB). By assuming an early phase of accelerated expansion where the CEB is satisfied,…
Dark Energy in String Theory
Bruno Valeixo Bento, Dibya Chakraborty, Susha L. Parameswaran +1
We consider various candidates for Dark Energy, motivated by string theory. Several no-go theorems push de Sitter string vacua, with , to the limits of theoretical control, a…
Fat Inflatons, Large Turns and the -problem
Dibya Chakraborty, Roberta Chiovoloni, Oscar Loaiza-Brito +2
It is commonly believed that a successful period of inflation driven by a single or several scalar fields requires a specific hierarchy of masses given by $M_{inf}\ll H \ll M_{heav…
