Title: Complex Quasiparticle Energy

Abstract

We show how calculate the energies and the widths of quasiparticle resonant states without solving the complex bcs equations. The method is based on BCS equations solved in the real representation including the continuum. In this representation the quasiparticle resonances are associated to the Gamow states of the mean field.

  • The dependence of quasiparticle effective chemical potential ..mu..* on excess quasiparticle number density n and the dependence of the critical value of n on temperature T in superconducting lead film with strong quasiparticle injection have been calculated from the experimental results of ''double steps'' in the I--V curve of a lead tunnel junction with strong quasiparticle injection. The calculated results agree qualitatively with Chang-Scalapino theory on the nonhomogeneous state and show the correctness of our explanation that the above phenomenon is caused by the existence of double energy gaps of the lead film.
  • The electron self-energy [ital Sigma]([bold k],[omega]) corresponding to the one-band Hubbard Hamiltonian on clusters of the square lattice has been obtained as a function of the band filling up to second order in the interaction parameter [ital U]. The [bold k] dependence of the self-energy is completely taken into account. As a consequence, the imaginary part of the self-energy shows a linear behavior for fillings close to one electron per site whereas for large doping rates the quadratic [omega] dependence characterizing Fermi liquids is recovered. The origin of this behavior has been investigated analytically: linear terms associated with nesting aremore » shown to exist in any finite-dimensional lattice although its numerical relevance decreases very rapidly for space dimensionality larger than two. Implications of these results on the renormalization factor [ital Z] have been analyzed. From a practical point of view, we conclude that a standard second-order perturbative treatment is quantitatively precise for [ital U] values of the on-site Coulomb interaction smaller than the bandwidth of the noninteracting spectrum.« less
  • The quasiparticle energy spectra associated with some memebrs of fullerene (curved graphitic geometries, e.g., C{sub 50}, C{sub 60}, C{sub 70}, and helical graphitic microtubules) are obtained anayltically within the Hartree-Fock mean-field approximation. The magnetization and magnetic susceptibility are calculated in the presence of a strong external magnetic field at zero temperature. Interesting theoretical predictions such as the single quasiparticle excitation energies for C{sub 50}, C{sub 50}{sup +}; C{sub 60}, C{sub 60}{sup +}; C{sub 70} and C{sub 70}{sup +} as well as the presence of an extra peak in de Haas--van Alphen oscillations for a helical graphitic microtubule are discussed inmore » terms of accessible experimental measurements.« less
  • The quasiparticle dispersion in the one-hole {ital t}-{ital t}{prime}-{ital t} {double_prime}-{ital J} model is studied. Both finite-size diagonalization and the self-consistent Born-approximation calculations have been performed and compared. The quasiparticle band structures in the hole- and electron-doped high-{ital T}{sub {ital c}} cuprates are qualitatively different. In the hole-doped compounds, the band maxima are located at ({plus_minus}{pi}/2,{plus_minus}{pi}/2), while in the electron-doped compounds the band maxima are located at ({pi},0) and its equivalent points. The angle-resolved photoemission data for the quasiparticle dispersion of Sr{sub 2}CuO{sub 2}Cl{sub 2} can be quantitatively reproduced using the one-band {ital t}-{ital t}{prime}-{ital t} {double_prime}-{ital J} model withmore » the three-site hopping term. {copyright} {ital 1996 The American Physical Society.}« less
