The gauge / gravity duality, one of the most important developments in theoretical physics over the last 20 years, allows to translate questions in quantum field theories to questions in quantum gravitational theories. Computations that are extremely complicated on one side of the duality are often much simpler on the other side. This opens up many new possible avenues, in particular for addressing problems in strongly coupled quantum field theories.
Our research group will work on these questions in collaboration with experts from Regensburg. The unique focus of the group consists of employing techniques from loop quantum gravity on the gravitational side. These allow to explore sectors of quantum gravity theories that are usually inaccessible using more standard, in particular perturbative, techniques. Our goal is to use these insights to learn about quantum field theories at a finite number of colors (e.g. “red”, “blue”, and “green” quarks in the strong nuclear interactions), which is not possible using only classical gravity.
