Abstract

We propose that the presence of a rotationally symmetric charge modulation in high-Tc superconductors is able to account for an anomalous quasiparticle dispersion revealed recently by angle-resolved photoemission spectroscopy (ARPES) experiments. We elaborate that the nodal quasiparticle is well defined at low energies, while the dispersion breaks up at the energy E1 and reappears at the energy E2. Our results are in agreement with both the ARPES and scanning tunneling microscopy experiments.
