Quasi-Local Energy in Loop Quantum Gravity

  title={Quasi-Local Energy in Loop Quantum Gravity},
  author={Jinsong Yang and Yongge Ma},
Although there is no known meaningful notion of the energy density of the gravitational field in general relativity, a few notions of quasi-local energy of gravity associated to extended but finite domains have been proposed. In this paper, the notions of quasi-local energy are studied in the framework of loop quantum gravity, in order to see whether these notions can be carried out at quantum level. Two basic quasi-local geometric quantities are quantized, which lead to well-defined operators… CONTINUE READING
