Quick Electromagnetically Induced Transparency Question

    Do you need a magnetic field for EIT, or just two electromagnetic beams with the right attributes?

    Thanks,

    If I remember correctly, you need some Zeeman splitting. The magnetic field of earth is sufficient, and you can use EIT to measure its field strength.

    Why would you need Zeeman splitting, if an atom already has three states without splitting any of them?

    If you use completely different states that is not an issue, you are right. I am not sure how sensitive the EIT effect is for different (degenerate) states if you have no Zeeman splitting.
