New experiments supporting Bohmian mechanics?

[Demystifier]

Do all Bohmian physicists working on relativistic BM use this concept of fundamental particles vs quasi-particles in the condense matter phonons analogy..

No. I guess I am the only one who, so far, proposed it explicitly. Implicitly, if you can read between the lines, it can also be seen in the work of Ilja Schmelzer and Forum posts by @atyy .

or does any still try to make the main bohmian non relativistic particles become suddenly able to create and annhiliate? what programme explore this? How successful.. and what are the main problems?

A not-so-long time ago, I was trying to make Bohmian mechanics inherently relativistic. How successful, judge by yourself:
