The quantum equation of state of the universe produces a small cosmological constant
Speaker(s): Tim Koslowski
Abstract: Relationalism is the strict disentanglement of physical law from the definition of physical object. This can be formalized in the shape dynamcis postulate that the objective evolution of the universe is described by an "equation of state of a curve in relational configuration space." The application... read more

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

PIRSA:13100067  ( MP4 Medium Res , MP3 , PDF ) Which Format?
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
