Checkerboard (negative surface tension)

Glazier & Graner 1993 reproduction — viva-cpm

J_ll=10 J_dd=8 J_ld=6 J_lM=12 J_dM=12 γ_ld=-3 γ_lM=+7 γ_dM=+8 T=10.0 λ=1.0 target: A_light=40.0 A_dark=40.0 initial condition: equilibrated_random

Finding: gamma_ld<0 yields a defect-ridden checkerboard with dominant light-dark contact and two transitions (~T=0 freeze, ~T=15 mixing), matching Figs 7-9 and Table I.

Fig 7 — checkerboard pattern at 10/100/1000/2000 MCS.

Fig 8 — total & fractional lengths, ⟨n⟩, moments.

Fig 9 — l-l, l-d, l-M interfaces vs MCS across T.

Table I — bulk moments vs temperature.
