Researchers constructed a family of nonperiodic embedded minimal surfaces of infinite genus in T x R, converging to T x R foliated by T, which then lift to minimal surfaces in R-3 that are periodic in horizontal directions but not vertical ones. The construction can be interpreted as disordered stacking of layers of periodically arranged catenoid necks. The richness in variety of disordered minimal surfaces is obtained by equations related to recent studies on the mean field equation and the Painleve VI equation. The work was inspired by experimental observations of twinning defects in periodic minimal surfaces, reproduced as special cases of stacking disorder.
We construct one-parameter families of nonperiodic embedded minimal surfaces of infinite genus in T x R, where T denotes a flat 2-tori. Each of our families converges to a foliation of T x R by T. These surfaces then lift to minimal surfaces in R-3 that are periodic in horizontal directions but not periodic in the vertical direction. In the language of crystallography, our construction can be interpreted as disordered stacking of layers of periodically arranged catenoid necks. Limit positions of the necks are governed by equations that appear, surprisingly, in recent studies on the mean field equation and the Painleve VI equation. This helps us to obtain a rich variety of disordered minimal surfaces. Our work is motivated by experimental observations of twinning defects in periodic minimal surfaces, which we reproduce as special cases of stacking disorder.
