Does anybody know papers in which the asymptotic safety approach has been applied to the "no boundary" proposal?
Asymptotic safety is a theory in theoretical physics that suggests that the fundamental laws of nature are fixed points, meaning that they are unchanged under certain transformations. This allows for the possibility of a theory of quantum gravity that is both well-defined and predictive.
The "no boundary" proposal, also known as the "Hartle-Hawking state", is a theory that suggests that the universe has no boundary in space or time. This theory is often used in conjunction with the idea of asymptotic safety to explain the initial conditions of the universe and the concept of time in the absence of a singularity.
Asymptotic safety and the "no boundary" proposal are often used together to explain the initial conditions of the universe. The idea of asymptotic safety provides a framework for a theory of quantum gravity, while the "no boundary" proposal helps to explain the origin of the universe and the concept of time.
If both asymptotic safety and the "no boundary" proposal are correct, it could lead to a better understanding of the fundamental laws of nature and provide a more complete theory of quantum gravity. It could also help to explain the origin of the universe and the concept of time in a more coherent way.
Currently, scientists are working to develop and refine mathematical models that incorporate both asymptotic safety and the "no boundary" proposal. One of the main challenges is reconciling these theories with other well-established theories, such as general relativity. Additionally, there is ongoing research to test the predictions of these theories through experiments and observations, which can be difficult due to the extreme conditions involved.
