Coplanar Repeats by Energy Minimization
[article]
2017

pre-print
This paper proposes an automated method to detect, group and rectify arbitrarily-arranged coplanar repeated elements via energy minimization. ...
The proposed energy functional combines several features that model how planes with coplanar repeats are projected into images and captures global interactions between different coplanar repeat groups ...

We present analytical arguments confirmed by numerical calculations that at zero temperature vacancies stabilize a conical state providing an example of "order by quenched disorder" effect. ...
In magnetic field the classical energy is minimized for spin configurations constrained by the magnetization of each triangular plaquette: S △ = H/(3J) . (2) The constraint leaves undetermined the orientation ...
