Magnetoquantum resistance (MR) in a perpendicular magnetic field (B{sub {perpendicular}}) and photoluminescence (PL) spectra are shown to be sensitively modulated by an in-plane field (B{sub {parallel}}) due to the B{sub {parallel}}-induced anticrossing of the energy-dispersion curves of the two quantum wells (QWs). Using a self-consistent density functional theory, they find very different B{sub {parallel}}-evolutions of the PL spectra for symmetric and asymmetric double QWs consistent with recent data. The MR is calculated using a linear response theory. The results consist of a superposition of two series of MR oscillations represented by ridges running nearly perpendicular to each other in the B = (B{sub {parallel}}, B{sub {perpendicular}}) plane. The data from GaAs/AlGaAs double QWs agree with this behavior.
