Lennard-Jones potential model is a widely used model in molecular dynamics simulations. The potential energy between two atoms is given by the Lennard-Jones equation:

V(r) = 4ε[(σ/r)^12 - (σ/r)^6]

where r is the distance between the two atoms, ε is the depth of the potential well, and σ is the distance at which the potential energy is zero.

At absolute zero Kelvin, the atoms are at their lowest energy state, and they do not move. Therefore, the potential energy between two atoms is simply the minimum value of the Lennard-Jones potential, which occurs at r = 2^(1/6)σ:

V(2^(1/6)σ) = -ε

So, for a noble gas at absolute zero Kelvin, the Lennard-Jones potential energy is a constant value of -ε.
