Higgs Criticality beyond the Standard Model
Thomas Steingasser, David I. Kaiser
Both parameters in the Higgs field's potential, its mass and quartic coupling, appear fine-tuned to near-critical values, which gives rise to the hierarchy problem and the metastab…
Nonlinear Dynamics of Preheating after Multifield Inflation with Nonminimal Couplings
Rachel Nguyen, Jorinde van de Vis, Evangelos I. Sfakianakis +2
We study the post-inflation dynamics of multifield models involving nonminimal couplings using lattice simulations to capture significant nonlinear effects like backreaction and re…
Relativistic Corrections to Nonrelativistic Effective Field Theories
Mohammad Hossein Namjoo, Alan H. Guth, David I. Kaiser
In this paper we develop a formalism for studying the nonrelativistic limit of relativistic field theories in a systematic way. By introducing a simple, nonlocal field redefinition…
Nonperturbative Dynamics Of Reheating After Inflation: A Review
Mustafa A. Amin, Mark P. Hertzberg, David I. Kaiser +1
Our understanding of the state of the universe between the end of inflation and big bang nucleosynthesis (BBN) is incomplete. The dynamics at the end of inflation are rich and a po…
Multifield Dynamics of Higgs Inflation
Ross N. Greenwood, David I. Kaiser, Evangelos I. Sfakianakis
Higgs inflation is a simple and elegant model in which early-universe inflation is driven by the Higgs sector of the Standard Model. The Higgs sector can support early-universe inf…
Restoring the sting to metric preheating
Bruce A. Bassett, Christopher Gordon, Roy Maartens +1
The relative growth of field and metric perturbations during preheating is sensitive to initial conditions set in the preceding inflationary phase. Recent work suggests this may pr…
