We investigate the effectiveness of entropic uncertainty,entanglement and steering in discerning quantum phase tran-sitions(QPTs).Specifically,we observe significant fluctuations in entropic uncertainty as the driving parameter traverses the phase transition point.It is observed that the entropic uncertainty,entanglement and quantum steering,based on the electron distribution probability,can serve as indicators for detecting QPTs.Notably,we reveal an intriguing anticorrelation relationship between entropic uncertainty and entanglement in the Aubry-André model.Moreover,we explore the feasi-bility of detecting a QPT when the period parameter is a rational number.These observations open up new and efficient avenues for probing QPTs.
