Query: Substantially enhanced deuteron-triton fusion probabilities in intense
  low-frequency laser fields   Deuteron-triton (DT) fusion is the primary fusion reaction used in controlled
fusion research, mainly for its relatively high reaction cross sections
compared to other fusion options. Even so, to attain appreciable reaction
probabilities very high temperatures (on the order of 10-100 million kelvins)
are required, which are extremely challenging to achieve and maintain. We show
that intense low-frequency laser fields, such as those in the near-infrared
regime for the majority of intense laser facilities around the world, are
highly effective in transferring energy to the DT system and enhancing the DT
fusion probabilities. The fusion probabilities are shown to be enhanced by at
least an order of magnitude in 800-nm laser fields with intensities on the
order of 10$^{21}$ W/cm$^2$. The demanding temperature requirement of
controlled nuclear fusion may be relaxed if intense low-frequency lasers are
exploited.
