Gravitational multifield dynamics on Higgs pre-inflation and preheating
Traditionally the problem of initial conditions for inflation has been treated separately from studies of reheating. To allow for a parametric-type reheating, the inflaton must be allowed to interact with (or decay to) other fields, and, these interactions should be present also during inhomogeneous preinflation. Could they prevent cosmic inflation to start in the first place? In a single-author publication Cristian answers this question for Higgs Inflation: once more, inflation always starts and passes the challenge!
