Starobinsky Inflation from String Theory?
Max Brinkmann, Michele Cicoli, Pietro Zito
Starobinsky inflation is currently one of the best models concerning agreement with cosmological data. Despite this observational success, it is still lacking a robust embedding in…
KKLT and the Swampland Conjectures
Ralph Blumenhagen, Max Brinkmann, Daniel Klaewer +2
Recently, various swampland conjectures have been proposed that every UV complete effective field theory should satisfy. In particular, these deal with the properties of AdS and dS…
dS Spaces and Brane Worlds in Exotic String Theories
Ralph Blumenhagen, Max Brinkmann, Andriana Makridou +2
We investigate string-phenomenological questions of Hull's exotic superstring theories with Euclidean strings/branes and multiple times. These are known to be plagued by pathologie…
Quantum Log-Corrections to Swampland Conjectures
Ralph Blumenhagen, Max Brinkmann, Andriana Makridou
Taking the anti-de Sitter minimum of KKLT and the large volume scenario at face value, we argue for the existence of logarithmic quantum corrections to AdS swampland conjectures. I…
A Note on the dS Swampland Conjecture, Non-BPS branes and K-theory
Ralph Blumenhagen, Max Brinkmann, Andriana Makridou
We point out that the de Sitter swampland conjecture would be falsified if classical fluxed Type IIA orientifold vacua with a single non-BPS D7-brane were indeed part of the string…
On the Existence of an L structure for the Super-Virasoro Algebra
Ralph Blumenhagen, Max Brinkmann
The appearance of L structures for supersymmetric symmetry algebras in two-dimensional conformal field theories is investigated. Looking at the simplest concrete example o…
