Even though nuclear physics is customarily
associated with very high field strengths and energies (in the
MeV to GeV range), we find that nuclear fusion could be
assisted at much lower scales, which should come within
reach of present-day or near-future XFEL facilities
(or with electrons) ... [see appended snaps]
Apart from the deformation of the potential
barrier, the time dependence plays a crucial role for
assisting tunneling through the Coulomb barrier, in close
analogy to the dynamically assisted Sauter-Schwinger effect ...
We found that the tunneling exponent is enhanced ...
Note that dynamically assisted tunneling
has already been observed experimentally in several other
The proposed dynamical assistance mechanism should also
work for other fusion reactions. An important example is
deuterium-deuterium fusion ...
In summary, our understanding of tunneling is still far from
complete and offers surprises which motivate further studies ...
After understanding the main mechanism better, the next
step would be to study whether it could be observed experimentally
and which scenario (e.g., beam-beam or beam-target
fusion, thermal or inertial fusion) might be most suitable.
These findings could then determine the potential for possible
future technological applications.
