Description
The universe at extremely early times is expected to be described by some theory of quantum gravity, although we still do not know precisely what quantum gravity actually is.
In modern approaches to quantum gravity, the path integral point of view provides a fundamental framework towards answering this pressing question. However, an evaluation or even just a precise definition of the path-integral for a full-fledged quantum gravity is one of the most important open problems in modern theoretical physics.
With the "Japan-UK Workshop on Quantum Gravity" we want to bring together experts working on different aspects of the gravitational path-integral, such as
- Gravitational Scattering Amplitudes;
- Complex Geometries and Exact WKB;
- Quantum Cosmology;
- Exact Methods and Resurgence Analysis;
with the long-term goal of providing innovative ways of tackling modern problems in quantum gravity.
This workshop serves as the kick-off meeting for the Royal Society International Collaboration Award Grant "Re-PaInt: A Resurgence Path-Integral approach to quantum gravity" shared between Masazumi Honda at Riken iTHEMS and Daniele Dorigoni at Durham University, and aimed at fostering and developing an international partnership between the two institutes, as well as the greater Japan and UK theoretical physics communities working on quantum gravity, broadly intended.
