N-flation with Hierarchically Light Axions in String Compactifications
  We present an explicit embedding of axionic N-flation in type IIB string
compactifications where most of the Kahler moduli are stabilised by
perturbative effects, and so are hierarchically heavier than the corresponding
N >> 1 axions whose collective dynamics drives inflation. This is achieved in
the framework of the LARGE Volume Scenario for moduli stabilisation. Our set-up
can be used to realise a model of either inflation or quintessence, just by
varying the volume of the internal space which controls the scale of the
axionic potential. Both cases predict a very high scale of supersymmetry
breaking. A viable reheating of the Standard Model degrees of freedom can be
achieved after the end of inflation due to the perturbative decay of the N
light axions which drive inflation.
