The Universal Renormalization Group Machine - 2

Frank Saueressig Radboud Universiteit Nijmegen
June 23, 2017 PIRSA:17060092
Quantum Gravity
Functional renormalization group techniques based on Wetterichs equation provide a powerful tool for studying the properties of gravity in the quantum regime and its connection to the observable low-energy world. Explicit computations in this framework require the evaluation of functional traces over operator-valued functions. In these lectures I will give a pedagogical introduction to the Universal Renormalization Group Machine, a combinatorial algorithm which allows evaluating such traces in a systematic way. Moreover, I will discuss flow equations for “composite operators” which may pave the route towards developing a microscopic description of quantum spacetime within the Asymptotic Safety approach.

Numerical loop quantum cosmology

Quantum Gravity
In the last decade various cosmological spacetimes have been quantized using the techniques of loop quantum gravity. To understand singularity resolution and decipher reliable Planck scale physics, development of new numerical methods and usage of high performance computing is critical in loop quantum cosmology. In recent years, these developments have robustly demonstrated resolution of singularities in quantum spacetimes. These methods have provided detailed understanding of the emergence of new physics at Planck scale, and of classicality when spacetime curvature becomes very small. Further, they have validated an effective spacetime description of the underlying quantum geometry -- a key ingredient of phenomenological predictions in loop quantum cosmology. These lectures will introduce these numerical methods.

Quantum Gravity from Lattice Gauge Theory via Holography

Masanori Hanada Kyoto University
June 22, 2017 PIRSA:17060088
Quantum Gravity
The gauge/gravity duality relates supersymmetric gauge theories to superstring/M-theory. Powerful Monte Carlo methods developed in lattice QCD can be applied to study the former,and from the simulation data we can extract the quantum gravitational effects. In this talk I will give a brief introduction to lattice gauge theory and supersymmetry on a lattice, and show some applications to quantum gravity via the gauge/gravity duality.
