Quantum oscillations in hole-doped high-temperature superconductors are difficult to understand within the prevailing views. An emerging idea is that of a putative normal ground state, which appears to be a Fermi liquid with a reconstructed Fermi surface. The oscillations are due to formation of Landau levels. Recently the same oscillations were found in the electron-doped cuprate, Nd2-x Cex CuO4, in the optimal to overdoped regime. Although these electron-doped nonstoichiometric materials are naturally more disordered, they strikingly complement the hole-doped cuprates. Here we provide an explanation of these observations from the perspective of density waves using a powerful transfer matrix method to compute the conductance as a function of the magnetic field.
