Query: Scale-dependent hemispherical asymmetry from general initial state
  during inflation   We consider a general initial state for inflation as the mechanism for
generating scale-dependent hemispherical asymmetry. An observable
scale-dependent non-Gaussianity is generated that leads to observable
hemispherical asymmetry from the super-horizon long mode modulation. We show
that the amplitude of dipole asymmetry falls off exponentially on small angular
scales which can address the absence of dipole asymmetry at these scales.In
addition, depending on the nature of non-vaccum initial state, the amplitude of
the dipole asymmetry has oscillatory features which can be detected in a
careful CMB map analysis. Furthermore, we show that the non-vacuum initial
state provides a natural mechanism for enhancing the super horizon long mode
perturbation as required to generate the dipole asymmetry.
