Abstract

The recently discovered two-phase phenomenon in financial markets [Nature421 (2003) 130] is examined with the German financial index DAX. Based on a realistic assumption, we introduce a dynamic feedback interaction to the Eguiluz–Zimmermann model [Phys. Rev. Lett.85 (2000) 5659]. Such an interaction generates a time correlation of volatility, and correctly produces the two-phase phenomenon.
