A privileged quantum state from causal structure
This thesis investigates a new proposal for a privileged ground state of a free scalar quantum field in arbitrary regions of spacetime. This Sorkin-Johnston (SJ) state, implicit in work by S. Johnston on quantum field theory on causal sets, is defined solely in terms of the spacetime causal structur...
