Properties of scalar perturbations generated by conformal scalar field
M. Libanov, S. Mironov, V. Rubakov
Primordial scalar perturbations may be generated when complex conformal scalar field rolls down its negative quartic potential. We begin with the discussion of peculiar infrared pr…

Q-balls with scalar charges
V. Rubakov, A. Levin
We consider Friedberg-Lee-Sirlin Q-balls in a (3+1)-dimensional model with vanishing scalar potential of one of the fields. The Q-ball is stabilized by the gradient energy of this…

Scalar tilt from broken conformal invariance
V. Rubakov, M. Osipov
Within recently proposed scenario which explains flatness of the spectrum of scalar cosmological perturbations by a combination of conformal and global symmetries, we discuss the e…
