More about this network
The idea that a discrete approach might be useful to quantize geometry and gravity has been revived recently, following the striking success of lattice gauge theory as a theory of the strong interaction. Discretized models allow one to construct theories which do not depend on an expansion in a small parameter. The most important new idea that this research team relies on is the use of fluctuating discretizations rather than a fixed lattice.
The partners involved have a record of collaboration stretching back over many years. The project envisaged has a multidisciplinary nature (mathematics, theoretical physics, computer science, solid state physics).
A large part of the effort will be devoted to numerical simulations, using new algorithms and state of the art hardware. This makes a collaboration even more necessary in order to avoid unnecessary duplication and allowing the different sites to benefit from the overall technical expertise.
