Response of macroscopic and microscopic dynamical quantifiers to the quantum critical region

At finite temperatures, the quantum critical region (QCR) emerges as a consequence of the interplay between thermal and quantum fluctuations. We seek suitable physical quantities, which during dynamics can give prominent response to QCR in the transverse field quantum XY model. We report that the ma...
