Figure 9
Structure factors of two different piecewise constant potentials shown in the insets are solved by the analytical solution of the RFA as well as by using different closures solved numerically with the OZ equations, namely Percus–Yevick (PY) (Percus & Yevick, 1958), hypernetted chain (HNC), MSA (Hansen & McDonald, 2013) and modified MSA (mMSA) (Gazzillo & Giacometti, 2003, 2004). For extreme values of the attractive well, such as those shown in (a), the closures might not be valid anymore and have to be verified against MD simulations; for more details, see the main text. |
