Abstract

The combined Rényi–Fisher entropy product of electrons plus holes displays a minimum at the charge neutrality points. The Stam–Rényi difference and the Stam–Rényi uncertainty product of the electrons plus holes, show maxima at the charge neutrality points. Topological quantum numbers capable of detecting the topological insulator and the band insulator phases, are defined. Upper and lower bounds for the position and momentum space Rényi–Fisher entropy products are derived.
