Am. Rudin et al., INTERACTION-INDUCED OSCILLATIONS OF THE TUNNELING DENSITY-OF-STATES IN A NONQUANTIZING MAGNETIC-FIELD, Physical review letters, 78(4), 1997, pp. 709-712
We study tunneling into an interacting disordered two-dimensional elec
tron gas in a nonquantizing magnetic field, which does not cause the s
tandard de Haas-van Alphen oscillations. Interaction induces a new typ
e of oscillation in the tunneling density of states with the character
istic period of cyclotron quantum <(h)over bar omega(c)>.
