[Pw_forum] the difference between the low- and high-frequency dielectric constants

[Suza W]

Dear All,

Using Eqn. 11 of PRL 89, 157602 (2002), the authors had got the value 5.09.
Could you anyone please show me how? Feeding volume, mass and frequency in
atomic units, I am unable to get that value if Z* is 1.96. Thanks in
advance for your kind kelp.
