Electrical conductivity of SiO(2) at extreme conditions and planetary dynamos

Ab intio molecular dynamics simulations show that the electrical conductivity of liquid SiO(2) is semimetallic at the conditions of the deep molten mantle of early Earth and super-Earths, raising the possibility of silicate dynamos in these bodies. Whereas the electrical conductivity increases unifo...
