DOI: 10.1007/jhep03(2021)299
Abstract: The Swampland Distance Conjecture (SDC) restricts the geodesic distances that scalars can traverse in effective field theories as they approach points at infinite distance in moduli space. We propose that, when applied to the subset… read more here.

Abstract: A bstractThe KKLT scenario in a warped throat, if consistent, provides a concrete counterexample to both the AdS scale separation and the dS swampland conjectures. First, we define and analyze the relevant effective field theory… read more here.

DOI: 10.1103/physrevd.100.084013
Abstract: Swampland conjecture has been recently proposed to connect early time cosmological models with the string landscape, and then to understand if related scalar fields and potentials can come from some fundamental theory in the high… read more here.

DOI: 10.1103/physrevd.99.103508
Abstract: We show how the inclusion of non-perturbative, {\em dynamical} quantum effects on the evolution of the inflaton can allow for an inflationary phase that is both consistent with cosmological constraints {\em and} avoids the problems… read more here.

DOI: 10.1142/s0218271821420293
Abstract: In this essay, we will take a wonderful ride on a dark bubble with strings attached, which carries our universe out of the swampland and makes it realizable in the landscape of string theory. To… read more here.

Gauss–Bonnet Inflation and the String Swampland
Sign Up to like & getrecommendations! Published in 2019 at "Universe"
DOI: 10.3390/universe5090200
Abstract: The swampland criteria are generically in tension with single-field slow-roll inflation because the first swampland criterion requires small tensor-to-scalar ratio while the second swampland criterion requires either large tensor-to-scalar ratio or large scalar spectral tilt.… read more here.
