Fermi momentum resolved charge order for spin-disordered stripes

For a doped antiferromagnet with short-range spin-stripe correlations and long-range charge-stripe order, we find that the manifestation of charge order abruptly changes as a function of momentum along the Fermi surface. The disorder averaged local density of states is almost perfectly homogeneous when integrated only over states that contribute to the nodal spectral weight, whereas it displays long-range charge-stripe order when integrated only over states that contribute to the antinodal spectral weight. An effectively two dimensional isotropic nodal liquid can thus coexist with static charge stripes provided there is no static spin order. We also study commensurate spin- and charge-stripe ordered systems wherein the Fermi surface consists of a nodal hole pocket and an open stripe band section. Due to the stripe order, the relation between hole density and size of a pocket will be reduced compared to that of a paramagnet by factors of 2 for even charge period and 4 for odd charge period, and we find an estimated upper limit on the area fraction of a hole pocket of 1.6% for charge-period four and 4% for charge-period five. We also discuss why electron pockets are not expected for a stripe ordered system and show that the open Fermi surface section may be electronlike with a negative Hall coefficient.
