Hi everybody!!!(adsbygoogle = window.adsbygoogle || []).push({});

Is there someone that can help me to prove that

[tex]

\omega^2E-k^2E=-ip_0k\times E+i\omega p\times E

[/tex]

imply that the dispersion relation is

[tex]

(k^\mu k_\mu)^2+(k^\mu k_\mu)(p^\nu p_\nu)=(k^\mu p_\mu)^2

[/tex]

Thanks in advance ;)

p.d. The reference for this formula is the paper of Carrol, Field, Jackiw, Limits on a Lorentz and parity violating modification of electrodynamics
