High Energy Theory Seminar: Partially massless gravity

Kurt Hinterbichler (Perimeter)
On de Sitter space, there exists a special value for the mass of a graviton for which the linear theory propagates 4 rather than 5 degrees of freedom. If a fully nonlinear version of the theory exists and can be coupled to known matter, it would have very interesting properties and could solve the cosmological constant problem. I will describe evidence for and obstructions to the existence of such a theory.

High Energy Theory Seminar: Conformal Invariance, Dark Energy and CMB NonGaussianity
February 4, 2013  2:00 pm
DRL 2N36
Emil Mottola (LANL)
A universe dominated by dark energy naturally gives rise to correlation functions possessing full conformal invariance. This is a consequence of the conformal group of flat 3dimensional spatial sections being isomorphic to the de Sitter symmetry group SO(4,1), and hence independent of specifi c model assumptions. Assuming this full symmetry holds leads to a de finite prediction for the shape of the nonGaussian CMB bispectrum, quite different from single field slow roll inflation.

Special "Evolution Cluster Search 2013" Seminar

Lynch Lecture Hall (Chemistry)
Erol Açkay, Princeton
“New frontiers in social evolution theory”
Cooperation between organisms is a major driving force of biological organization at all levels, from single cells to whole ecosystems. Understanding the evolutionary dynamics of cooperation and other social traits therefore is a central goal of evolutionary theory. I will talk about my recent work that aims to advance the frontiers of social evolution theory in two directions.
