In the documentation, the first parameter in the "lj/cut/coul/debye"

pair style is referred to several times as the Debye length. However,

in the equation presented and in LAMMPS itself this parameter seems to

be the inverse Debye length, having units of 1/distance. . This makes

sense since the Debye length is usually represented by lambda; kappa

(as here) means the inverse. I found this confusing, and others

probably have as well.

Fix: on the page http://lammps.sandia.gov/doc/pair_lj.html,

"kappa = Debye length (inverse distance units)"

should read "kappa = inverse of the Debye length (inverse distance units)"

and

"where kappa is the Debye length"

should read "where kappa is the inverse of the Debye length".
