Abstract

We argue that charges in underdoped La_2-xSr_xCuO₄ move in a dissipative environment of strong spatial and temporal fluctuations. The unusual temperature dependence of the Hall angle known as "the separation of lifetimes" is reinterpreted and attributed to the appearance of the thermally activated component in the effective number of carriers with the temperature increase. We consider the temperature interval above T_c where localization effects can be neglected.
