Nonlinear cosmological structure with ultralight bosons via modified
  gravity
  Ultra-light bosons as dark matter has become a model of major interest in
Cosmology, due to the possible imprint of a distinct signature in the cosmic
structure both at the linear and non-linear scales. In this work we show that
the equations of motion for density perturbations for this kind of models can
be written in terms of a modified gravitational potential. Taking advantage of
this parallelism, we use the MG-PICOLA code originally developed for modified
gravity models to evolve the density field of axion models with and without
self-interaction. Our results indicate that the quantum potential adds extra
suppression of power at the non-linear level, and it is even capable of
smoothing any bumpy features initially present in the mass power spectrum.
