Probing Cosmology through Higher-Order CMB Lensing Statistics
Shu-Fan Chen - Columbia University
Solid Inflation
Alberto Nicolis - Columbia University
I will describe a cosmological model where primordial inflation is driven by a 'solid', defined as a system of three derivatively coupled scalar fields obeying certain symmetries and spontaneously breaking a certain subgroup of these. The symmetry breaking pattern differs drastically from that of…
Cosmological Limits on Neutrino-Neutrino Scattering and Particle Physics in the Early Universe
Kris Sigurdson - University of British Columbia
In the standard model neutrinos are assumed to have streamed across the Universe since they last scattered at the weak decoupling epoch when the temperature of the standard-model plasma was ~MeV. The shear stress of free-streaming neutrinos imprints itself gravitationally on the Cosmic Microwave…
Primordial non-Gaussianity in the CMB and large-scale structure
Kendrick Smith - Perimeter Institute for Theoretical Physics
Precision Holographic Cosmology
Paul McFadden - Durham University
We discuss holography for cosmology, focusing on a class of slow-roll inflationary spacetimes that are holographically dual to a perturbative RG flow between two nearby CFTs. The cosmological power spectrum and non-Gaussianities may be calculated directly from the dual QFT using conformal…
C++ template magic - Part 3
A general introduction to c++ templates. As motivation the possibilities will be demonstrated in short examples in order to show the might of these programming techniques. After covering the fundamentals of templates the following topics will be discussed: polymorphism, traits, template…
