From recent observational data two significant directions have been made in the field of
theoretical cosmology recently. First, we are now able to make use of present observations …

The past two decades have seen transformative advances in cosmology and string theory.
Observations of the cosmic microwave background have revealed strong evidence for …

A groundbreaking text and reference book on twenty-first-century classical physics and its
applications This first-year graduate-level text and reference book covers the fundamental …

We report the results of a joint analysis of data from BICEP2/Keck Array and Planck. BICEP2
and Keck Array have observed the same approximately 400 deg 2 patch of sky centered on …

This pedagogical review is devoted to quintessential inflation, which refers to unification of
inflation and dark energy using a single scalar field. We present a brief but concise …

We describe the design of a new polarization sensitive receiver, spt-3g, for the 10-meter
South Pole Telescope (spt). The spt-3g receiver will deliver a factor of~ 20 improvement in …

A bstract Flux couplings to string theory axions yield super-Planckian field ranges along
which the axion potential energy grows. At the same time, other aspects of the physics …

A bstract The continuous shift symmetry of axions is at the heart of several realizations of
inflationary models. In particular, axion monodromy inflation aims at achieving super …

Dark Matter is essential for structure formation in the late Universe so it must be stable on
cosmological time scales. But how stable exactly? Only assuming decays into relativistic …

A bstract We consider a broad class of inflationary models that arise naturally in super-
gravity. They are defined in terms of a parameter α that determines the curvature and cutoff …
