Merging of Landau levels in a strongly-interacting two-dimensional electron system in silicon

Abstract

We show that the merging of the spin- and valley-split Landau levels at the chemical potential is an intrinsic property of a strongly-interacting two-dimensional electron system in silicon. Evidence for the level merging is given by available experimental data.
