If the spectra of H=p^2 + x^2 +ix^3 remains the same as h=p^2+x^2 + ip^3 .Then what is the importance of PT symmetry ?

16 August 2019 0 1K Report

PT symmetry loses its importance from the above Hamiltonians under real spectra . Did you ever realise that ? My point is not to hurt anybody conception but to explore physics .
