Noether's Charge in the Super-Group Field Cosmo

摘要

We analyze the third quantization of a model of supergroup field cosmology with gauge symmetry. The effect of creation and annihilation of bosonic and fermionic universes in the multiverse is also analyzed. We also construct a third-quantized Noether charge which is conserved even if the number of universes is not conserved. Finally, we construct both the third-quantized BRST and the third-quantized anti-BRST charges for this theory and use them to show that creation and annihilation of universes is a unitary process.
