Abstract:
We studied interactions between the coherent excitations on
disconnected arcs along a “bare” Fermi surface (the so-called Fermi
arcs
FAs) seen by angle-resolved photo emission spectroscopy (ARPES) in
several underdoped (UD) cuprates and incommensurate charge density wave
(IC CDW) ordering at lowering of the temperature. The carriers on FAs
scatter strongly on the short-wavelength potential of CDW. The large
momentum transfer relates FAs with the electronic states lying deeply
under the chemical potential thus involving into consideration the Fermi
liquid interactions. At low temperatures IC CDW may fully destroy low
lying excitations on the Fermi arcs, leaving electrons on the pocket at
the $\Gamma$-point
as the only charged elementary excitations in the CDW phase in
UD cuprates. The results infer competition between superconducting and
CDW order parameters.
