Witryna21 lut 2024 · spin chain. We focus on the entanglement entropy lS(t) of a subchain of length l for a quantum Ising chain in transverse field undergoing a time-periodic driving of period τ [39, 40]. The entanglement entropy increases linearly in time, until in the long-time limit an asymptotic τ-periodic value St()∞ l is reached 7. The asymptotic value ... Witryna9 wrz 2024 · In fact, s 0 s i would be equal to s 0 2 if there were no correlations between spins. . . this is essentially the definition of “correlation”. This motivates the definition of the correlation function. (9.4.4) G i ( T, H) = s 0 s i − s 0 2. The correlation function is essentially a measure of “peer pressure”: How is the spin at site i ...
