A small negative-density component with equation of state 1/3≤w≤1 can lift H0 from 67.4 to about 74, but the coupled quintom model realizing it either misses the CMB peak or gives H0=68.55.
(4.16) Although a sign ± depends on roots of the condition x2 1−x2 3 = 1, the fixed point is either saddle or unstable point

Resolving Hubble Tension with Quintom Dark Energy Model
A small negative-density component with equation of state 1/3≤w≤1 can lift H0 from 67.4 to about 74, but the coupled quintom model realizing it either misses the CMB peak or gives H0=68.55.
