The Standard Model Extension (SME) is a generic parametrization for Lorentz violation and the phenomenological consequences of minimal gravity sector SME are usually studied using post-Newtonian expansion that requires spacetime to be asymptotically flat. However, there term in this which these approximations unable make predictions; known as $t$ puzzle. present paper studies model spontaneous ...

Local flatness is a property shared by all the spin foam models. It ensures that theory's fundamental building blocks are flat requiring locally trivial parallel transport. In context of simplicial Lorentzian theory, we show local main responsible for emergence geometry independently details model. We discuss asymptotic analysis EPRL amplitudes in large quantum number regime, highlighting inter...
