Interaction-Induced Oscillations of the Tunneling Density of States in a Nonquantizing Magnetic Field
We study tunneling into an interacting disordered two-dimensional electron gas in a nonquantizing magnetic field, which does not cause the standard de Haasvan Alphen oscillations. Interaction induces a new type of oscillation in the tunneling density of states with the characteristic period of cyclotron quantum {h_bar}{omega}{sub c}. {copyright} {ital 1997} {ital The American Physical Society}
