Spin Orbit Coupling

The conductance of GaAs/AlGaAs quantum dots vs. magnetic field reveals an important difference between large and small dots: the conductance peak at B = 0 produced by strong spin-orbit coupling for large dots becomes a minimum for small dots. These data demonstrate that spin-orbit effects are suppressed in small dots.
