Gaussian, exponential, and power-law decay of time-dependent correlation functions in quantum spin chains

Joachim Stolze, Angela Nöppert, Gerhard Müller

Dynamic spin correlation functions $< S_{i}^{x} (t) S_{j}^{x} >$ for the 1D $S = 1/2$ $X X$ model $H = - J Σ_{i} {S_{i}^{x} S_{i + 1}^{x} + S_{i}^{y} S_{i + 1}^{y}}$ are calculated exactly for finite open chains…
