That is the ZPF stress-energy diagonal is for pressure P
(P,-P,-P,-P) i.e. Trace is -2P
If we stick in plates or somehow break the rotational symmetry (rotating
superconducting disks that phase lock to the vacuum Goldstone phase?)
Then
(-P, +aP, + bP, + cP), the trace is now (1 - a - b - c)P
This is quintessence and it can perhaps be done with the Shipov torsion
field.

That is the ZPF stress-energy diagonal is for pressure Energy Density
dE/dV & Pressure P
w(ZPF) = P/(dE/dV) = -1 from EEP of GR
(dE/dV,-dE/dV,-dE/dV,dE/dV), i.e. Trace is -2(dE/dV) = (1 + 3w)(dE/dV)
Compare to EM radiation where
w = P/(dE/dV) = + 1/3
( dE/dV, +(1/3)dE/dV, +(1/3)dE/dV, +(1/3)dE/dV), i.e. Trace = +2dE/dV =
(1 + 3w)(dE/dV)
Note that dark energy is P < 0 & dE/dV > 0.
If we stick in plates or somehow break the rotational symmetry (rotating
superconducting disks that phase lock to the vacuum Goldstone phase?)
Then
( dE/dV, +a(dE/dV), + b(dE/dV), + c(dE/dV)), the trace is now (1 + a + b
+ c)dE/dV
1 + 3w = 1 + a + b + c
w = (a + b + c)/3
This is quintessence when w < -1/3 and it can perhaps be done with the
Shipov torsion field.
