I don't know how to treat a center of mass corrections.(adsbygoogle = window.adsbygoogle || []).push({});

Suppose to have a Slater determinant of N single-particle wavefunctions. If I make a traslation to center of mass of system, this is mean to move all particle in the following way:

R_i ---> R_i - (sum_j {R_j}/N)

But how have I to correct the gradient and laplacian terms?

I think that there would be a kinetic energy correction. Is it true?

Thank's!
