Gravitational reheating at strong coupling
Alex Buchel
We use gauge/gravity correspondence to study the gravitational reheating of strongly coupled gauge theories in the rapid exit from the long inflationary (de Sitter) phase. We estim…
Hot Big Bang from inflation without the inflaton reheating
Alex Buchel
According to the standard lore, a prolonged inflation leaves a quantum field theory in a cold, low entropy state. Thus, some mechanism is needed to reheat this post-inflationary st…
Gravitational susceptibility of QGP
Alex Buchel
We use and cascading gauge theory holographic models to extract the general features of the gravitational susceptibility of strongly coupled nonconformal quark-g…
Stability of the cascading gauge theory de Sitter DFPs
Alex Buchel
We study stability of the Dynamical Fixed Points (DFPs) of the cascading gauge theory at strong coupling in de Sitter space-time. We compute the spectra of the perturbative fluctua…
Master equations for de Sitter DFPs
Alex Buchel
We develop master equations to study perturbative stability of de Sitter Dynamical Fixed Points (DFPs) of strongly coupled massive quantum field theories in space-time dimens…
The quest for a conifold conformal order
Alex Buchel
The holographic duality between cascading gauge theory and type IIB supergravity on warped deformed conifold with fluxes reveals exotic thermal phases with nonzero expectation valu…
