Figure 7From: Trapped-ion quantum simulation of tunable-range Heisenberg chainsVelocity of excitations. (a) Position vs. time of a spin when it starts being polarized (〈 σ z ( i ) 〉>0.02) in a system with 1/ r 3 decaying interaction (detuning 10MHz). (b) Corresponding spinon velocity as a function of time. The black line corresponds to the spinon velocity in the Haldane-Shastry model.Back to article page
