An Estimation of Wave Attenuation Factor in Ultrasonic Assisted Gravity Drainage Process
It has been proved that ultrasonic energy can considerably increase the amount of oil recovery in an immiscible displacement process. Although many studies have been performed on investigating the roles of ultrasonic waves, based on the best of our knowledge, little attention has been paid to evaluate wave attenuation parameter, which is an important parameter in the determination of the energy...
متن کاملQuantum phase transitions in d-wave superconductors
Motivated by the strong, low temperature damping of nodal quasiparticles observed in some cuprate superconductors, we study quantum phase transitions in d(x(2)-y(2)) superconductors with a spin-singlet, zero momentum, fermion bilinear order parameter. We present a complete, group-theoretic classification of such transitions into seven distinct cases (including cases with nematic order) and anal...
متن کاملDisorder induced stripes in d-wave superconductors
Stripe phases are observed experimentally in several copperbased high-T c superconductors near 1/8 hole doping. However, the specific characteristics may vary depending on the degree of dopant disorder and the presence or absence of a low-temperature tetragonal phase. On the basis of a Hartree–Fock decoupling scheme for the t–J model, we discuss the diverse behavior of stripe phases. In particu...
متن کاملInelastic scattering rates in d-wave superconductors
The inelastic scattering rates of quasiparticles in a two-dimensional d-wave superconductor, which arise from interactions with either acoustic phonons or other quasiparticles, are calculated within second order perturbation theory. We discover a strong enhancement of scattering with collinear momenta, brought about by the special kinematics of the two-dimensional fermions with Dirac-like spect...
متن کاملSubharmonic gap structure in d-wave superconductors
We present a self-consistent theory of current-voltage characteristics of d-wave/d-wave contacts at arbitrary transparency. In particular, we address the open problem of the observation of subharmonic gap structure ~SGS! in cuprate junctions. Our analysis shows that ~i! the SGS is possible in d-wave superconductors; ~ii! the existence of bound states within the gap results in an even-odd effect...
