Two fields quintessential Higgs Inflation
  We study a two-field quintessential inflation model with non-minimal coupling
term where an exponential quintessence potential coupled to Higgs potential
from inflationary era. This non-minimal two-field model is shown to provide
very good consistency to the recent cosmological observation. Although, the
quintessence field is sub-dominant during inflation, it can remove Higgs
instability in the early universe which is a serious problem. Also, considering
quintessence from early time helps overcoming its initial condition problem.
