Primordial bispectrum from multifield inflation with nonminimal couplings
Realistic models of high-energy physics include multiple scalar fields. Renormalization requires that the fields have nonminimal couplings to the spacetime Ricci curvature scalar, and the couplingsExpand

Multifield inflation after Planck: the case for nonminimal couplings.
Multifield models of inflation with nonminimal couplings are in excellent agreement with the recent results from Planck. Across a broad range of couplings and initial conditions, such models evolveExpand

Higgsed Chromo-Natural Inflation
A bstractWe demonstrate that Chromo-Natural Inflation can be made consistent with observational data if the SU(2) gauge symmetry is spontaneously broken. Working in the Stueckelberg limit, we showExpand

Higgsed Gauge-flation
A bstractWe study a variant of Gauge-flation where the gauge symmetry is spontaneously broken by a Higgs sector. We work in the Stueckelberg limit and demonstrate that the dynamics remainExpand

Multifield dynamics of Higgs inflation
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 inflation if it has aExpand

A Multi-Hop Relay Station Software Architecture Design, on the Basis of the WiMAX IEEE 802.16j Standard
TLDR
In order to enable rapid and cost-effective deployment of WiMAX networks, relay technology which does not require backhaul line, can be considered as an essential feature for performing a successful business development. Expand

Multifield Inflation after Planck: Isocurvature Modes from Nonminimal Couplings
Recent measurements by the {\it Planck} experiment of the power spectrum of temperature anisotropies in the cosmic microwave background radiation (CMB) reveal a deficit of power in low multipolesExpand

Universality and scaling in multi-field $\alpha$-attractor preheating
We explore preheating in multi-field models of inflation in which the field-space metric is a highly curved hyperbolic manifold. One broad family of such models is called $\alpha$-attractors, whoseExpand

Gauge-preheating and the end of axion inflation
We study the onset of the reheating epoch at the end of axion-driven inflation where the axion is coupled to an Abelian, U(1), gauge field via a Chern-Simons interaction term. We focus primarily onExpand

Preheating after multifield inflation with nonminimal couplings. II. Resonance structure
This is the second in a series of papers on preheating in inflationary models comprised of multiple scalar fields coupled nonminimally to gravity. In this paper, we work in the rigid-spacetimeExpand
