Late-time large-distance asymptotics of the transverse correlation functions of the XX chain in the space-like regime

30 Aug 2019 Göhmann Frank Kozlowski Karol K. Suzuki Junji

We derive an explicit expression for the leading term in the late-time, large-distance asymptotic expansion of a transverse dynamical two-point function of the XX chain in the spacelike regime. This expression is valid for all non-zero finite temperatures and for all magnetic fields below the saturation threshold... (read more)
