PIRSA:15050085  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Physical records and emergence of information in the gravitationally dominated universe
Speaker(s): Tim Koslowski
Abstract: The second law of thermodynamics appears to be a universal law of physics. This universality suggests that entropy and with it information theory is part of the foundations of physics. In this talk I take the opposite (probably more conservative) approach: I assume that the dynamics of relational d... read more

Asymptotic safety in a pure matrix model
Speaker(s): Tim Koslowski
Abstract: The connection between two-dimensional Euclidean gravity and pure matrix models has lead to may fundamental insights about quantum gravity and string theory. The pure matrix model is thus a blueprint for the connection between discrete models and Euclidean quantum gravity. I will report on work with... read more

Asymptotically safe matrix models
Speaker(s): Tim Koslowski
Abstract: The functional renormalization group is a tool in the systematic search for Euclidean QFTs that works with very little input: All one needs to specify is a field content, symmetries and a notion of locality. The functional renormalization group then allows one to scan this theory space for b... read more

A Cosmological Sector in Loop Quantum Gravity
Speaker(s): Tim Koslowski
Abstract: A classical Hamiltonian system can be reduced to a subsystem of "relevant observables" using the pull-back under a Poisson embedding of the "relevant phase space" into the "full phase space". Since a quantum theory can be thought of a noncommutative phase space, one encounters the problem of the emb... read more
