Real-space dynamic renormalization group: Systematics T<Tc

We extend our previous analysis of the two-dimensional kinetic Ising model using the real-space dynamic-renormalization-group (RSDRG) method to the ordered phase. This extension involves a discussion of spontaneous symmetry breaking within the context of a perturbative treatment using uncoupled cells as a zeroth-order approximation. This leads us to consider the introduction of an effective local magnetic field which simulates the average local order and necessitates the generalization of the RSDRG approach to the case of a finite magnetic field. We explain the role of the local order and proceed to calculate various observables. We note that our results match smoothly with our results for T>Tc.
