PT symmetry breaking in optical systems

  1. Jul 24, 2015 #1
    There are very results published about PT symmetry breaking in optical systems, with effects like anysotropical transmission resonance in waveguides.
    But if PT symmetry is broken in a optical system and CPT symmetry must always be respected, then what C symmetry is broken in a optical system?

    Do you have a reference?
    I guess the breaking is related to material properties - the material does not have to be symmetric. Exact T transformation would mean you have to replace matter-waveguides by antimatter-waveguides - I doubt they did that!

    A matter effect. The matter is not symmetric, there is no PT violation on a fundamental level.
