Description:
Author(s): Vassilios Yannopapas We demonstrate that the process of band-gap creation in periodic solids such as atomic, photonic, or phononic crystals can be viewed as spontaneous PT-symmetry breaking in the framework of a complex frequency band structure. This allows the use of ordinary artificial structures such as Bragg stacks ... [Phys. Rev. A 89, 013808] Published Fri Jan 10, 2014
