Abstract
We show that a basic difference between the electron- and hole-doped cuprates is their proximity to two different quantum critical points in a 2D free fermion system on a square lattice and that the spin dynamics observed recently for the first time in the electron-doped Nd2−xCexCuO4, very different from that in the hole-doped cuprates, can be understood as a consequence of this effect.
