A Potential Mechanism for Inflation from Swampland Conjectures
  Inflation is the currently accepted paradigm for the beginnings of the
Universe. To explain the observed almost scale invariant spectrum of density
perturbations with only a slight spectral tilt, inflation must have been "slow
roll", that is with a potential with sufficiently small slope. While the origin
of inflationary structure is intrinsically quantum mechanical, gravity gets
treated semiclassically within inflationary models. Recent work, in terms of
the so called de-Sitter swampland conjecture, has called into question whether
slow roll inflation is consistent with a complete theory of quantum gravity in
the presence of a positive vacuum energy density, which is a key ingredient in
the inflationary paradigm. In this work, we show that, in fact, if we
understand this conjecture correctly and with another swampland conjecture, the
so-called distance conjecture, involved we get a potential mechanism for slow
roll inflation and we argue that here fine-tuning is not a technical problem.
