Here is White's 2011 paper. Unfortunately, it's miles over my head.
A few notes:
1. This requires a very specific model of spacetime, the Chung-Freese metric
2. The article is cited only once in INSPIRE-HEP, by a publication from the same institute, indicating it's not well read/accepted
3. The experiment described in the paper should be fairly simple to do. There are no reports of the experiment being successfully replicated.
The paper describes a way to get negative energy density from positive energy. However, none of the other bad effects (e.g. causality violation, non-unitarity) have been resolved.
None of these items completely rules out this model, but Alcubierre's original paper, by contrast, was cited 136 times and there have been numerous follow-on papers. This implies that most people in the field don't take White's idea seriously. And of course, if we live in something other than the Chung-Freese spacetime, all bets are off.
BTW, the Van Den Broeck paper/metric on which OAUP's current warp drives are based have been cited 32 times.
