Abstract
We calculate single-particle properties of short-range-ordered stripe states using Monte Carlo simulations of collective charge-density wave (CDW) order parameters coupled to fermions on a 2d square lattice. For superconducting bond-centered stripes with a d -wave form factor, we find a valence-bond "glass" which coexists with low-energy quasiparticles featuring interference phenomena, in agreement with recent scanning tunneling microscopy (STM) measurements on underdoped Bi2 Sr2 CaCu2 O8+δ and Ca2-x Nax CuO2 Cl2. Together with earlier work, our calculations provide a link between CDW signatures seen in STM and those in magnetic neutron scattering.
