Kinetics of excitations on the Fermi arcs in underdoped cuprates at low temperatures
Abstract
The Fermiliquidlike (FL) resistivity recently observed in clean Hg1201 below the pseudogap temperature was related to carriers at the nodal points on the Fermi surface (FS) (N. Barišić , arXiv:1207.1504, doi:10.1073/pnas.13019891109). We show that this has important implications for the electronic spectrum of underdoped (UD) cuprates as a whole. Photoemission experiments (angleresolved photoemission spectroscopy) in other cuprates picture the spectrum as “metallic arcs” separated from each other by regions with large energy gaps. We rigorously solve the kinetic equation in such a model. The Fermi arcs' carriers contribute to the FL resistivity, if scattering between the opposite nodal points admits the umklapp processes. The Hall coefficient defines the effective number of carriers on the arcs and at weak magnetic fields it has a positive sign. All parameters that determine the arcs' widths are measurable experimentally. We conclude that the T^{2} resistivity gives support to the Fermi arcs' concept and argue that the idea of a reconstructed FS in UD cuprates is not consistent with the latter.
