PT Symmetry in Optics, Exceptional Points and Bound States in the Continuum
Explore the fascinating world of PT symmetry in optics, exceptional points, and bound states in the continuum in this 34-minute conference talk by Prasanta K Panigrahi. Delve into the fundamentals of PT symmetric systems, including their potential applications and unique properties. Examine the redefinition of norms in these systems and analyze specific examples of PT symmetric potentials. Investigate the relationship between supersymmetry (SUSY) and PT symmetric phases, exploring how broken SUSY phases occur in different parameter domains with real eigenvalues. Learn about bound states in the continuum and their occurrence in PT-broken phases. Study scattering phenomena in PT symmetric systems and discover the connection between isospectral deformation and the Korteweg-de Vries (KdV) equation. Understand how light behaves at exceptional points, where group velocity vanishes. Explore experimental observations of PT-symmetric quantum mechanics, including coherent perfect absorbers (CPA) and PT-CPA lasers. Examine PT symmetric solutions in modified KdV equations and complex superposed solutions. Gain valuable insights into this cutting-edge field of non-Hermitian physics and its potential applications in optics and quantum mechanics. Read more
