  Disorder-induced heating (DIH) prevents ultracold neutral plasma into
electron strong coupling regime. Here we propose a scheme to suppress
electronic DIH via optical lattice. We simulate the evolution dynamics of
ultracold neutral plasma constrained by three-dimensional optical lattice using
classical molecular dynamics method. The results show that for experimentally
achievable condition, electronic DIH is suppressed by a factor of 1.3, and the
Coulomb coupling strength can reach to 0.8 which is approaching the strong
coupling regime. Suppressing electronic DIH via optical lattice may pave a way
for the research of electronic strongly coupled plasma.
