Just found an article on a german science news site about a new approach to achieve nuclear fusion by quantum tunneling induced by x-ray lasers.
This sounds similar to Holmlids approach?
The research was done at theoretical physics institute at Helmholtz-Zentrum Dresden-Rossendorf.
We consider deuterium-tritium fusion as a generic example for general fusion reactions. For initial kinetic energies in the keV regime, the reaction rate is exponentially suppressed due to the Coulomb barrier between the nuclei, which is overcome by tunneling. Here, we study whether the tunneling probability could be enhanced by an additional electromagnetic field, such as an x-ray free electron laser (XFEL). We find that the XFEL frequencies and field strengths required for this dynamical assistance mechanism should come within reach of present-day or near-future technology.
