Smectic Pores and Defect Cores

Interface Focus (2012)

Elisabetta A. Masumoto, Randall D. Kamien and Christian Santangelo

Riemann's minimal surfaces, a one-parameter family of minimal surfaces, describe a bicontinuous lamellar system with pores connecting alternating layers. We ...

Frustrated Order on Extrinsic Geometries

Physical Review Letters (2012)

Badel L. Mbanga, Gregory M. Grason and Christian Santangelo

We study, numerically and theoretically, defects in an anisotropic liquid that couple to the extrinsic geometry of a surface. Though ...
