Fig. 1. Schematic plot of external magnetic field intensity with a periodic change.
Fig. 2. The eigenstate occupation numbers of one-dimensional Ising model keep invariant under longitudinal periodic magnetic pulses (along the -axis). Here is the number of magnetic pulses, each point in the graph represents the mean of 32 neighboring states, the green and red curves are the exponential and QMC fitting results, respectively.
Fig. 3. DOS of one-dimensional Ising model. Thick red curve: Ising model without external field; blue curve: Ising model with a longitudinal field; thin green curve: Ising model with a transverse field.
