From: Controlling symmetry and localization with an artificial gauge field in a disordered quantum system
Two pulse sequences belonging to different symmetry classes. The sequences correspond to the data shown in Fig. 2, and were obtained using two different values of the symmetry-control parameter \(\tilde \varphi\) in (5): \(\tilde \varphi = 0\) (a) and \(\tilde \varphi = - 3\pi {\mathrm{/}}5\) (b), for which the system belongs respectively to the orthogonal and unitary symmetry class. In the orthogonal class the time sequence has symmetry axes τ; a CBS peak will appear at the kicks symmetric to the initial kick with respect to such axis. In the unitary class no CBS peak will exist. In both cases, the symmetry-insensitive CFS peaks are expected to occur at integer multiples of the period (N = 10)
