Strong-coupling scale and frame-dependence of the initial conditions for chaotic inflation in models with modified (coupling to) gravity
Dmitry Gorbunov, Alexander Panin
A classical evolution in chaotic inflationary models starts at high energy densities with semi-classical initial conditions presumably consistent with universal quantum nature of a…

Fatal youth of the Universe: black hole threat for the electroweak vacuum during preheating
Dmitry Gorbunov, Dmitry Levkov, Alexander Panin
Small evaporating black holes were proposed to be dangerous inducing fast decay of the electroweak false vacuum. We observe that the flat-spectrum matter perturbations growing at t…

On the minimal active-sterile neutrino mixing in seesaw type I mechanism with sterile neutrinos at GeV scale
Dmitry Gorbunov, Alexander Panin
Renewed interest in GeV-scale sterile neutrinos capable of explaining active neutrino oscillations via see-saw type I mechanism has been expressed in several proposals of direct se…
