Tetratic Phase in 2D Crystals of Squares
Robert Löffler, Lukas Siedentop, Peter Keim
Melting in 2D is described by the celebrated Kosterlitz-Thouless-Halperin-Nelson-Young (KTHNY) theory. The unbinding of two different types of topological defects destroys translat…

Stealthy and hyperuniform isotropic photonic bandgap structure in 3D
Lukas Siedentop, Gianluc Lui, Georg Maret +5
In photonic crystals the propagation of light is governed by their photonic band structure, an ensemble of propagating states grouped into bands, separated by photonic band gaps. D…
