P. Coleman et al., HOW SHOULD WE INTERPRET THE 2 TRANSPORT RELAXATION-TIMES IN THE CUPRATES, Journal of physics. Condensed matter, 8(48), 1996, pp. 9985-10015
We observe that the appearance of two transport relaxation times in th
e various transport coefficients of cuprate metals may be understood i
n terms of scattering processes that discriminate between currents tha
t are even, or odd under the charge-conjugation operator. We develop a
transport equation that illustrates these ideas and discuss its exper
imental and theoretical consequences.
