Phys. Rev. B 78, 144508 (2008) [6 pages]Electronic properties of disordered valence-bond stripes in cuprate superconductorsReceived 17 September 2008; published 13 October 2008 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 Bi2Sr2CaCu2O8+δ and Ca2−xNaxCuO2Cl2. Together with earlier work, our calculations provide a link between CDW signatures seen in STM and those in magnetic neutron scattering. © 2008 The American Physical Society URL:
