Spontaneous generated coherence

[vtahmoorian]

Hi everyone
Is there anyone who can explain when does Spontaneously generated coherence(SGC) happen and how?
Thank you in advance

I'm sorry you are not finding help at the moment. Is there any additional information you can share with us?

Thank you dear Greg for your comment,
actually I started to study more about it and found that SGC happens when we are dealing with decays in an atom, when a three level Landa type atom (for example) decays to lower levels and the final state of the atom becomes a coherent superposition of states, we will have SGC , I came up with another question that "What makes a superposition of states a coherent superposition?" , and I wrote it in the forum too.now as I am more investigating I face more challenges that I have asked under the title of:" What makes a superposition of states a coherent superposition?"
Thank you again and if anyone can help me on this question too , I will appreciate .
