West, Tomaz Prosen, and Tsampikos Kottos<br/>We study the Loschmidt echo F(t) for a class of dynamical systems showing critical chaos. Using a kicked rotor with singular potential as a prototype model, we found that the classical echo shows a gap (initial drop) 1−F_{g} , where F_{g} scales as F_{g} (α,ϵ,η)=f_{cl} (χ_{cl} ≡η^{3−α} /...<br/><img src="http://prola.aps.org/graphics/rapid30x30.gif" width="30" height="30" alt="Rapid Communication"/><br/>[Phys.
