【 摘 要 】

Using the variational trial wave function based on the string picture we study the motion of a single mobile hole in the stripe phase of the doped antiferromagnet. The holes within the stripes are taken to be static, the undoped antiferromagnetic domains in between the hole stripes are assumed to have alternating staggered magnetization, as is suggested by neutron-scattering experiments. The system is described by the t-t'-t -J model with realistic parameters and we compute the single-particle spectral density.
