Fig. 5: Calculated nanotexture of the monoclinic insulating phase.
From: Nanoscale self-organization and metastable non-thermal metallicity in Mott insulators
Calculated real space distribution of the shear strain ϵ2(r) deep inside the monoclinic insulating phase. The colours correspond to the three equivalent shear-strain vectors \({{{{{{{{\boldsymbol{\epsilon }}}}}}}}}_{2,1}=(+\sqrt{3}/2,+1/2)\), \({{{{{{{{\boldsymbol{\epsilon }}}}}}}}}_{2,2}=(-\sqrt{3}/2,+1/2)\) and ϵ2,3 = (0, − 1), shown on the left, which characterize the three equivalent monoclinic twins, see Eq. (5). The figure is a superposition of three different ones. The first is obtained plotting the y-component of ϵ2(r) on a colour scale from −1 (plum) to 0 (white); the second plotting the x-component from \(+\sqrt{3}/2\) (blue) to 0 (white), and the third plotting still the x-component but now from \(-\sqrt{3}/2\) (orange gold) to 0 (white). Evidently, when the lighter regions of all three plots overlap that implies both x and y components are nearly zero, thus a small strain. We note that the interfaces between different domains evidently satisfy the curl-free condition (9).
