Measurement-induced phase transition: A case study in the nonintegrable model by density-matrix renormalization group calculations
Q Tang, W Zhu - Physical Review Research, 2020 - APS
We study the effect of local projective measurements on the quantum quench dynamics. As
a concrete example, a one-dimensional Bose-Hubbard model is simulated by the matrix …
