Definition of the relevant dimensionless parameters in the problem.

Dimensionless Parameters	Description
ΔT/T0	Magnitude of tension fluctuations (Fig. 1e,f).
W/T0	Relative strength of cell-cell adhesion W and average cortical tension T0 (Fig. 1b).
$\rho \equiv N{L}_0^2∕A_T$	Normalized system density (with AT and N being the total area of the system and the number of cells, respectively; Fig. 1d).
P0L0/T0	Relative magnitude of normal to tensional forces.
τT/τR	Ratio of persistence time of tension fluctuations and characteristic timescale τR ≡ ηT L0/T0 of dissipation at vertices.
