Xr. Wang et al., Reply to "Comment on 'Dephasing of conduction electrons due to zero-point fluctuation' " - art. no. 117302, PHYS REV B, 6411(11), 2001, pp. 7302-NIL_713
We point out that the central theme in the paper by Wang, Xiong, and Wang [
Phys. Rev. B 61, R5090 (2000)] is the inseparability of electron degrees of
freedom and those of electromagnetic field (EMF). The dephasing of conduct
ion electrons due to zero-point fluctuation (ZPF) of EMF is because experim
ents probe electron degrees of freedom only. The treatment of ZPF of EMF in
the above paper is oversimplified, and a proper handling of the effects of
electron-EMF coupling is required.
