This is a general question (maybe stupid).

I am very interested in Double Field Theory, Exceptional Field Theory, Generalized Geometry and Non-geometries in general and I would like to do my PhD in this field. I know that it is quite popular at Imperial College London and at Max Planck Institute, but in other universities?
Which are the strongest research groups (in Europe) in this field?

Unfortunately, it is difficult to give a complete answer to this question since there are many research groups and universities that are conducting research in this field. However, some of the strongest research groups in Europe include:1. Imperial College London - This is one of the leading institutions in the field, with a strong focus on string theory and related areas.2. University of Cambridge - The Maths Department at Cambridge is home to one of the world's foremost experts on Exceptional Field Theory, Dr. Chris Hull.3. University of Amsterdam - The UvA is home to a number of leading researchers in the field of Generalized Geometry and Non-geometries, including Dr. Daniel Berman, Prof. Jean-Claude Hausmann, and Prof. Robbert Dijkgraaf.4. University of Utrecht - The Utrecht University houses a large research group focusing on Double Field Theory, led by Dr. Martin Cederwall.5. Max Planck Institute for Physics - The MPI for Physics is home to a number of experts in the field of String Theory, including Prof. Hermann Nicolai and Prof. Anton Kapustin.Finally, there are numerous other universities and research institutes in Europe that are active in this field, including the University of Paris, the University of Bonn, and the University of Zurich.
 

1. What is Double/Exceptional Field Theory (DEFT)?

Double/Exceptional Field Theory (DEFT) is a theoretical framework that aims to unify different approaches to quantum gravity, such as string theory and loop quantum gravity. It is based on the idea of "doubling" the number of dimensions in space-time, creating a 12-dimensional space, and introducing exceptional structures known as exceptional Jordan algebras.

2. How is DEFT related to non-geometry?

DEFT is closely related to non-geometry because it proposes a new geometric framework for describing space-time that goes beyond the traditional notions of space and time. In DEFT, space-time is described in terms of exceptional structures rather than the traditional geometric concepts of points, lines, and curves.

3. What are the advantages of using DEFT over traditional approaches to quantum gravity?

DEFT has several advantages over traditional approaches to quantum gravity. Firstly, it provides a unified framework that can incorporate different theories, such as string theory and loop quantum gravity. Secondly, it offers a new perspective on space-time that may help to resolve some of the conceptual issues that arise in traditional approaches. Finally, DEFT allows for the possibility of new insights and predictions that may not be possible in traditional approaches.

4. How does DEFT address the issue of singularities in general relativity?

In general relativity, singularities are points in space-time where the curvature becomes infinite, and the laws of physics break down. DEFT proposes that these singularities can be resolved by introducing exceptional structures, which modify the geometry of space-time. This allows for a smoother and more continuous description of space-time, without the need for singularities.

5. Are there any experimental tests for DEFT?

Currently, there are no direct experimental tests for DEFT. However, some predictions of DEFT, such as the existence of new particles and extra dimensions, may be testable in future experiments, such as the Large Hadron Collider. Additionally, DEFT offers a new framework for understanding and potentially resolving some of the outstanding problems in theoretical physics, such as the unification of gravity with the other fundamental forces.
