I have been waiting to see a paper like this one. It has more descriptive properties of BECs than any I have seen before. Guess I have not been looking that hard since it came out in 2001.

Now the paper is primarily about a 1-dimensional realization of a BEC using Josephson Junctions and therefore more concerned with an experimental test than a 3-d application. Yet it gives me my first view of how rich in energy states a BEC in an inhomogenous environment can be.

I have been avoiding the condensed matter preprints of the Cornell archives. That must therefore be where all the BEC papers can be found. I wonder if 'hopping' is still an acceptable technical term. And the 'hidden sector' makes me think of Bohmian mechanics.

We seem to be in a revolution of theoretical physics. LQG theory derives spacetime and the big bang and now quantum mechanics. Soon it may derive string theory and have something to say about BECs. But apparently a TOE is not needed to come to an understanding of the interaction of BECs with the environment.

As you know my concern is with a Dark Matter BEC. But it seems that BECs have univesal properties.

Like I do not already have enough work to do.

Thanks,

Richard
