Since there are alternate regions of positive and negative energy densities in squeezed light, does that mean that the negative energy density parts gravitate repulsively? Since the stress energy would turn negative.

2$\begingroup$ I don't think 'squeezed light' means what you seem to think it means. $\endgroup$– Jon CusterCommented Feb 1 at 14:04

$\begingroup$ @JonCuster I think the misunderstanding is that squeezed light has a quasiprobability distribution with positive and negative parts, but that those don't correspond to positive and negative energy densities $\endgroup$– Quantum MechanicCommented Feb 1 at 15:20

$\begingroup$ I was thinking, since negative energy densities lead to gravitational repulsion, that the negative energy density regions in squeezed light also should have a gravitational repulsive effect. $\endgroup$– PeterCommented Feb 1 at 16:00

1$\begingroup$ An example of stress-energy tensor calculations for a squeezed state can be found in this paper, sect. IV. And yes, there are indeed negative energy densities. $\endgroup$– A.V.S.Commented Feb 1 at 19:17
