Possible polarisation and spin dependent aspects of quantum gravity
arXiv:0704.1669 · doi:10.1142/S0218271808012164
Abstract
We argue that quantum gravity theories that carry a Lie algebraic modification of the Poincare' and Heisenberg algebras inevitably provide inhomogeneities that may serve as seeds for cosmological structure formation. Furthermore, in this class of theories one must expect a strong polarisation and spin dependence of various quantum-gravity effects.
