We make use of classical lattice simulations in 3+ 1 dimensions to study the preheating
stage of Higgs Inflation in Einstein-Cartan gravity. Focusing for concreteness on a simplified …

We discuss the present state and planned updates of CosmoLattice, a cutting-edge code for
lattice simulations of non-linear dynamics of scalar-gauge field theories in an expanding …

These lecture notes provide a pedagogical introduction to some aspects of the inflationary
cosmology, including the background scalar field dynamics, generation of primordial seed …

We develop a precise analytic description of oscillons—long-lived quasiperiodic field lumps—
in scalar field theories with nearly quadratic potentials, eg, the monodromy potential. Such …

A bstract In certain models of inflation, the postinflationary reheating of the Universe is not
primarily due to perturbative decay of the inflaton field into particles, but proceeds through a …

We investigate the formation and decay of oscillons during the post-inflationary reheating
epoch from inflaton oscillations around asymptotically flat potentials $ V (\varphi) $ in the …

One of the key predictions of the standard inflationary paradigm is the quantum mechanical
generation of the transverse and traceless tensor fluctuations due to the rapid accelerated …
