Scale-dependent bias from the primordial non-Gaussianity with a
  Gaussian-squared field
  We investigate the halo bias in the case where the primordial curvature
fluctuations, $\Phi$, are sourced from both a Gaussian random field and a
Gaussian-squared field, as $\Phi({\bf x}) = \phi({\bf x}) + \psi({\bf x})^2 -
<\psi({\bf x})^2>$, so-called "ungaussiton model". We employ the
peak-background split formula and find a new scale-dependence in the halo bias
induced from the Gaussian-squared field.
