Distance between the general dimension of master and slave for high mismatched Rössler systems. Upper panel, color map denoting the normalized distance between the \(D_{q}\) curves of the master and the slave, \(\Delta D_{q}^{*}\) as a function of the parameter q (y axis) and the coupling strength \({\upsigma }\) (x axis). Vertical dashed lines show the negative and positive zipper effect regions (as distance decreasing to a minimum fixed value). Bottom panel, the normalized distance between the \(D_{q}\) curves of the master and the slave calculated as the norm between them, \(||\Delta D_{q}^{*}||\) as a function of \({\upsigma }\) in the \(q\le 0\) (red dashed curve), \(q>0\) (yellow dot-dashed curve) intervals and in the whole range of q (solid blue line). At \({\upsigma }\sim 3\), the negative part of \(D_{q}\) has completed its synchronization, and the positive part starts a gradual approach to the master curve. The zipper effect completes around \({\upsigma }\sim 6\). At \({\upsigma }\sim 7\) the system exits the synchronization window with a reverse zipper effect. The positive part of \(D_{q}\) gradually separates from the master curve (and thus the distance from the master increases) while the negative part of \(D_{q}\) remains with the same close distance to the master. Vertical dashed lines show the negative and positive zipper effect regions.
