From: Controlled state transfer in a Heisenberg spin chain by periodic drives
Robustness of the state transfer with N = 4. (a) The transfer fidelity F(tout) of the spin chain. The transfer fidelity F(tout) for different values of h (orange line) or J1 (black-dashed line). One of the parameters (h or J1) has a derivation from the ideal value \(h=-\,\frac{1}{2}\), \({J}_{1}=\frac{\sqrt{3}}{2}\), while other parameters J2 = 1, Δ = −1 are keep unchanged. Breaking fidelity of spin chain with sinusoidal driving (b), (c) triangular-well driving, and (d) square-well driving. The blockade fidelity BF(tout) for different values of amplitude(red line) and frequency (blue-dashed line), where the ideal parameters are Aj = 30.06, Bj = 36.56, Cj = 25, ω = 25.
