We investigate the effectiveness of entropic uncertainty, entanglement and steering in discerning quantum phase transitions(QPTs). Specifically, we observe significant fluctuations in entropic uncertainty as the drivi...

We study the one-dimensional tight-binding model with quasi-periodic disorders,where the quasi-period is tuned to be large compared to the system size.It is found that this type of model with large quasi-periodic diso...

Ultracold atoms trapped in optical superlattices provide a simple platform for realizing the seminal Aubry–André–Harper(AAH)model.However,this model ignores the periodic modulations on the nearest-neighbor hoppings...
