We study the D-dimensional high-density correlation energy Ec of the singlet ground state of two electrons confined by a harmonic potential with Coulombic repulsion. We allow the harmonic potential to be anisotropic and examine the behavior of Ec as a function of the anisotropy α-1. In particular, we are interested in the limit where the anisotropy goes to infinity (α→0) and the electrons are restricted to a lower-dimensional space. We show that tuning the value of α from 0 to 1 allows a smooth...[Show more]
