Query: Interaction-induced oscillations of the tunneling density of states in a
  non-quantizing magnetic field   We study tunneling into interacting disordered two-dimensional electron gas
in a non-quantizing magnetic field, which does not cause the standard de Haas--
van Alphen oscillations. Interaction induces a new type of oscillations in the
tunneling density of states with the characteristic period of cyclotron
quantum.
