Question

Does the Casimir Effect violate the Quantum Inequalities?

Answer 1

the Casimir Effect is able to produce negative energy densities for an finite amount of time. So it does not violate the Quantum Inequalities.

I know than Casimir effect have constraints on the magnitude of the negative energy produced but i don't understand why are you saying that it can do this only for a finite amount of time..For what i read you need to separate the plates from each other to stop the attraction between them (negative energy) but maybe i completely misunderstood the subject.

Since the negative energy density in the Casimir effect is static, it can be averaged for arbitrarily long times. Thus the Casimir effect violates the averaged weak energy condition and the quantum inequalities. 1 It is, however, violated by non-minimally coupled scalar fields . that makes up the plates.

Answer 2

Since the negative energy density in the Casimir effect is static, it can be averaged for arbitrarily long times. Thus the Casimir effect violates the averaged weak energy condition and the quantum inequalities. 1 It is, however, violated by non-minimally coupled scalar fields that makes up the plates.
