Bipartite temporal Bell inequality for squeezed coherent state of inflationary perturbations
No violation of the bipartite temporal Bell inequality occurs for coherent states of primordial perturbations, with only slight differences from the squeezed vacuum case at large squeezing and a unique dependence on the imaginary phase of the wave function.
