Null states and time evolution in a toy model of black hole dynamics
Abstract Spacetime wormholes can provide non-perturbative contributions to the gravitational path integral that make the actual number of states e S in a gravitational system much smaller than the number of states e S p $$ {e}^{S_{\textrm{p}}} $$ predicted by perturbative semiclassical effective fie...
