Abstract

A class of two-parameter relative complexity measures is presented. Several important properties are proved. As an example we consider the Dicke model that describes a single-mode bosonic field interacting with an ensemble of N two-level atoms. There is a quantum phase transition in the limit. It is found that the relative complexity is an excellent marker of the quantum phase transition.
