PIRSA:16110051  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Quantum spaces are modular
Speaker(s): Laurent Freidel
Abstract: In this talk I will review the construction of space starting purely from quantum mechanics and without assuming that the notion of space is attached to a preconceived notion of classical reality. I will show that if one start with the simplest notion of a quantum system encoded into the Heisenberg ... read more

PIRSA:16090060  ( MP4 Medium Res , MP3 , PDF ) Which Format?
The relative locality of quantum spacetime
Speaker(s): Laurent Freidel
Abstract: Should we revisit the concept of space solely based on quantum mechanics? Do we need a radically new physical principle to address the problem of quantum gravity? In this talk I will adress these questions. I will review what are the central challenges one faces when trying to understand the t... read more

PIRSA:15040169  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Metastring theory and Modular spacetime
Speaker(s): Laurent Freidel
Abstract: In this talk I will review a recent reformulation of string theory which does not rely on an a priori space-time interpretation or a pre-assumption of locality and include form the onset stringy symmetries such as T-duality. I will explain how this resulting theory, called metastring, leads to form... read more

PIRSA:14020144  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Non equilibrium thermodynamic of gravitational screens
Speaker(s): Laurent Freidel
Abstract: In this talk I will review the evidence for a mysterious and deep relationship between gravitational dynamics and thermodynamics. I will show how we can extend this connection to non equilibrium thermodynamics. Using the fact that the gravitational equations are fundamentally holographic, we express... read more
