Abstract

We address weak localization (WL) of electrons in a two-dimensional ballistic classically chaotic billiard of antidots. According to a recent proposal ballistic WL is sensitive to the transport relaxation and phase-coherence times as well as to the Ehrenfest time {\it t$_{E}$} and to the Lyapunov exponent {\it lambda} of the classical system. This results in a non-trivial effect of the ...
