Scale-dependent bias from multiple-field inflation
  We provide a formula for the scaling behaviour of the inflationary bispectrum
in the 'squeezed' limit where one momentum becomes much smaller than the other
two. This determines the scaling of the halo bias at low wavenumber and will be
an important observable for the next generation of galaxy surveys. Our formula
allows it to be predicted for the first time for a generic inflationary model
with multiple light, canonically-normalized scalar fields.
