Abstract

We solve a popular effective Hamiltonian of competing d-density-wave and d-wave superconductivity orders, self-consistently at the mean-field level for a wide range of doping and temperatures. The theory predicts a temperature dependence of the d-density wave order parameter seemingly inconsistent with the neutron-scattering and muon scattering resonance experiments of the cuprates. We further calculate thermodynamic quantities, such as chemical potential, entropy, and specific heat. Their distinct features can be used to test the existence of the d-density-wave order in cuprates.
