The evolution of a domain wall in a L = 12 spin crystal, comprising of multiple spin-excitations. a, b Short range spin-spin interaction, and c, d Long-range spin-spin interaction. a, c Absent the Floquet field (\(\bar{\eta }=0\)), the domain wall thermalizes as excitations are free to hop. b, d Fully dimerized crystal (\(\bar{\eta }=1\)). b Boundary excitations between the wall are exchanged coherently, and the domain wall maintains its state in (b) or partially thermalizes in (d). The results in a–d agree well with numerical calculation of the spin evolution, see Supplementary Fig. 6.
