Hi Matt,
Concerning the third cumulant, my problem is to use a particular model
for it. Some articles (Frenkel and Rehr, PRB 48 (1993) 585; Araujo et
al, PRB 74 (2006) 184102) show how to use the Einstein model on Artemis,
since these articles show the expressions that should be defined for

Hi Kleber:
I think of the Debye model as a model for the stiffness of the bond
between two atoms that is like a spring. The vibration depends on the
length of the spring (distance between the atoms) and the stiffness of
the spring as related through the Debye temperature. Above the Debye
Hi Kleber,
I'd like to use the third cumulant option in Artemis, but considering the
Debye model. Artemis has a Debye function for the second cumulant
(Debye-Waller factor) but not to the third. How could this be done in
Artemis?
The debye and eins functions in Artemis/Ifeffit calculates
