Extended Data Fig. 5: Numerical simulation results of the spin-echo decoherence dynamics.

a, The crystal structure of YVO4. b, System size scaling of the spin-echo decoherence profiles for different numbers of simulated spins from N = 2 to N = 10 ions. The decay profiles start to converge approximately when N > 8 ions. c, Effects of on-site disorder on spin-echo decoherence dynamics, simulated for different disorder strengths W. After the early-time transient (t < 1 μs) where the decay rate is independent of on-site disorder, spin decoherence slows down, indicating a crossover from an interaction-dominated to a disorder-dominated regime. d, Effects of initial spin polarization, ηpol, on spin-echo decoherence dynamics. e, Normalized coherence for the decay time traces shown in d. Upon rescaling, the decay profiles overlap for different polarization values of ηpol, indicating that the decoherence dynamics are independent of initial spin polarization.
