The Swampland Spectrum Conjecture in Inflation

Abstract

The quantum gravity conjectures that aim to separate the landscape from the swampland among the low energy theories were originally formulated in the context of scalar field spaces spanned by moduli. Because these conjectures have implications for cosmology they have recently been considered in a more general context for scalar field theories with potentials, in particular inflation. From an effective field theory perspective the presence of a potential induces a natural metric that makes the distance measure $D_V$ along scalar field trajectories dependent on the potential. The present paper proposes a modified formulation in terms of $D_V$ of those conjectures that involve trajectory distances.
