Gravitons from a loop representation of linearised gravity

  title={Gravitons from a loop representation of linearised gravity},
  author={Madhavan Varadarajan},
Loop quantum gravity is based on a classical formulation of 3+1 gravity in terms of a real SU(2) connection. Linearization of this classical formulation about a flat background yields a description of linearised gravity in terms of a real U(1) × U(1) × U(1) connection. A ‘loop’ representation, in which holonomies of this connection are unitary operators, can be constructed. These holonomies are not well defined operators in the standard graviton Fock representation. We generalise our recent… CONTINUE READING
