Comparison between Theory and Some Recent Experiments on Quantum Dephasing

We report on a quantitative comparison between our theory of quantum dephasing at low temperatures and some recent experimental results [D. Natelson {\it et al.}, Phys. Rev. Lett. {\bf 86}, 1821 (2001); A.B. Gougam {\it et al.}, J. Low Temp. Phys. {\bf 118}, 447 (2000); F. Pierre {\it et al.} cond-mat/0012038].
