Thermodynamic properties of the d-density wave order in cuprates
Wu, Congjun · Liu, W. Vincent
Original · EN
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 temperature. The theory predicts a temperature dependence of the d-density wave order parameter seemingly inconsistent with the neutron scattering and μSR 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.
