{"step_background":"Background\nThe Lennard-Jones potential models soft repulsive and attractive (van der Waals) interactions. Hence, the Lennard-Jones potential describes electronically neutral atoms or molecules. The commonly used expression for the Lennard-Jones potential is:\n\n$V_{\\mathrm{LJ}}(r)=4 \\varepsilon\\left[\\left(\\frac{\\sigma}{r}\\right)^{12}-\\left(\\frac{\\sigma}{r}\\right)^6\\right]$\n\nwhere r is the distance between two interacting particles, epsilon is the depth of the potential well (usually referred to as 'dispersion energy'), and sigma is the distance at which the particle-particle potential energy V is zero (often referred to as 'size of the particle').\n\nTo get force, we just use the negative gradiant of Lennard-Jones potential (by definition):\n\n$\\vec{F}=-\\frac{\\partial U}{\\partial \\vec{r}}=-\\left(\\frac{\\partial U}{\\partial x} ; \\frac{\\partial U}{\\partial y} ; \\frac{\\partial U}{\\partial z}\\right)$","step_description_prompt":"Based on lennard jones potential with potential well depth epislon that reaches zero at distance sigma, write a function that calculates the forces between two particles whose three dimensional displacement is r. The inputs of the function contain a float sigma, a float epsilon and r, which is a 1 by 3 array of float numbers. The output is force, which is a 1 by 3 array of float numbers."}
