The past two decades have witnessed a surge of interest in exploringcorrelation and coherence measures to investigate quantum phase transitions(QPTs). Here, motivated by the continued push along this direction, we proposea measure which is built upon the so-called degree of coherence, and advocateusing the susceptibility of our measure to detect QPTs. We show that ourmeasure can capture both the notions of coherence and correlations exhibited inbipartite states and therefore represents a hybrid of these two notions.Through examining the XXZ model and the Kitaev honeycomb model, we demonstratethat our measure is favorable for detecting QPTs in comparison to many previousproposals.
