Odd as it sounds, light and matter decouple at strong enough coupling! <br /><br />Check out this paper:<br />https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.112.016401Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-13869903.post-71186482325651226502021-10-14T05:59:04.721-05:002021-10-14T05:59:04.721-05:00Hi Professor Natelson

Following that reasoning, because only some photons make the transition from virtual to real, the free space radiation rate is altered by the cavity.<br />Does that reasoning make any sense or is it off the mark?<br />Mayer Landaunoreply@blogger.comtag:blogger.com,1999:blog-13869903.post-82315930298032784032021-10-10T23:49:35.156-05:002021-10-10T23:49:35.156-05:00I haven't read this in depth, but I've bee...I haven't read this in depth, but I've been meaning to ..<br /><br />https://www.nature.com/articles/srep12956#Abs1Stevehttps://www.blogger.com/profile/14514301100480098429noreply@blogger.com
