Liouville theory and Holographic Cosmology
Daniel Lord Harlow - Massachusetts Institute of Technology (MIT) - Center for Theoretical Physics
I will explain how Liouville theory with complex values of its parameters arises naturally in speculative holographic cosmologies. We will encounter Liouville theory of both the ``spacelike'' and ``timelike'' variety. I will then use this as motivation to present some new results on the analytic…
Dictionaries and Wavefunctions in dS/CFT and AdS/CFT
Douglas Stanford - Stanford University
I discuss bubble collisions from the perspective of an observer in a hat. In particular, I emphasize the breaking and restoration of conformal symmetry, as well as (independence of) initial conditions and rate equations. A cartoon version of the problem, Mandelbrot percolation, makes computations…
Choosing equations of state for neutron star inspiral
Jocelyn Read - California State University, Fullerton
On the fast scrambling conjecture
Patrick Hayden - Stanford University
Motivated by the consistency of black hole complementarity, Sekino and Susskind have conjectured that no physical system can "scramble" its internal degrees of freedom in time faster than (1/T) log S, where T is temperature and S the system's entropy. By considering a number of toy examples and…
An Effective Field Theory Dual of FRW Spacetime
We investigate a simple FRW spacetime realized by a brane construction. This also comes from a Coleman-de Luccia decay from a metastable de Sitter. We motivate a dual description in terms of a low energy effective field theory (EFT) on FRW in one lower dimensions. This EFT is coupled to gravity with…
Microphysics to macrophysics: Astrophysics and gravitational wave science opportunities in the advanced detector era and beyond
Richard O'Shaughnessy - University of Wisconsin-Milwaukee
Micromanaging and Accounting in de Sitter Holography
Bart Horn - Stanford University
I will discuss recent work engineering "semi-holographic" constructions of de Sitter space in string theory, using elliptic fibrations and orientifolds to uplift known Freund-Rubin compactifications. The dual brane construction is compact and provides a microscopic realization of the dS/dS…
Electromagnetic interaction of binary neutron star magnetospheres
Neutron star mergers represent one of the most promising sources of gravitational waves (GW), while that the presence of strong magnetic fields may offer the possibility of a characteristic electromagnetic signature allowing for concurrent detection. In this talk will be presented a new hybrid…
Uplifting AdS/CFT to Cosmology
Eva Silverstein - Stanford University
Starting from AdS/CFT, one can introduce ingredients which produce cosmological solutions, including metastable de Sitter and its decay to FRW. In the de Sitter case, this produces a compact brane construction which mirrors the dS/dS correspondence realizing de Sitter as a pair of warped throats…
Bulk Physics from CFT
Gauge/gravity duality is our most complete construction of quantum gravity, but it gives in a simple way only the observations of an observer at the AdS boundary. I discuss various issues regarding the representation of the bulk physics.
Unsolved Problems in Modelin Neutron Star-Neutron Star and Black Hole Neutron Star Binary Mergers
Matthew Duez - Washington State University
Black hole-neutron star (BHNS) binary mergers areimportant gravitational wave sources and (possibly) gamma ray burst progenitors. Fully relativisticsimulations have only recently begun to try to capture neutron star physics beyond the polytrope approximation. In this talk we discuss the numerical…
