    "abstract": "We have performed quantum molecular dynamics simulations for dense helium to\nstudy the nonmetal-to-metal transition at high pressures. We present new\nresults for the equation of state and the Hugoniot curve in the warm dense\nmatter region. The optical conductivity is calculated via the Kubo-Greenwood\nformula from which the dc conductivity is derived. The nonmetal-to-metal\ntransition is identified at about 1 g/ccm. We compare with experimental results\nas well as with other theoretical approaches, especially with predictions of\nchemical models.",
