      abstract     = {We present experiments on molecular density fluctuations in
                      liquid and supercritical (SC) CO2 using small-angle neutron
                      scattering. Thermal density fluctuations in SC-CO2 determine
                      susceptibility and correlation length identifying the Widom
                      line at their maxima. Droplet formation occurs at the
                      gas–liquid line and between 20 and 60 bar above the Widom
                      line, the corresponding borderline identified as the Frenkel
                      line. The droplets start to form spheres of constant radius
                      of ≈ 45 Å and transform into rods and globules at higher
                      pressure. Droplet formation represents a liquid–liquid
                      (polymorphic) phase transition of the same composition but
                      different density, whose difference defines its order
                      parameter. Polymorphism in CO2 is a new observation
                      stimulating interesting discussions on the topics of
                      gas-like to liquid-like transition in SC fluids and
                      polymorphism since CO2 represents a “simple” van der
                      Waals liquid in contrast to water, which is the most widely
                      studied liquid showing polymorphism in its supercooled
                      state.},
