Geometry and symmetries in lattice spinor gravity

Understand

Lattice spinor gravity is a proposal for regularized quantum gravity based on fermionic degrees of freedom.

• In our lattice model the local Lorentz symmetry is generalized to complex transformation parameters.
• The difference between space and time is not put in a priori, and the euclidean and Minkowski quantum field theory are unified in one functional integral.
• The metric and its signature arise as a result of the dynamics, corresponding to a given ground state or cosmological solution.
