Hund{close_quote}s-rule effects in the {ital f}{sup 1}-{ital f}{sup 2} Anderson impurity model: Renormalization of Hund{close_quote}s-rule Coulomb interactions down to low energies

Journal Article Landgraf, J M ; Rasul, J W - Physical Review, B: Condensed Matter

We examine the problem of an Anderson impurity model where the lowest configurations are {ital f}{sup 1} and {ital f}{sup 2}, with a Hund{close_quote}s-rule splitting (corresponding to Hunds first rule) present. We calculate (using the 1/{ital N} expansion) the single-particle spectrum in the limit of large ferromagnetic triplet-singlet splitting, and find the spectrum to be mostly equivalent to that of a zero Hund{close_quote}s-rule splitting model with reduced hybridization. At low energies, however, additional features arise on a scale given by the Kondo temperature. The results illustrate how the effects of a strong Hund{close_quote}s-rule interaction are renormalized down to low energies,more »« less

Coulomb screening in low-energy nuclear reactions

Journal Article Bencze, G ; Chandler, C - Physical Review, C (Nuclear Physics); (United States)

Coulomb screening effects are studied in very-low-energy nuclear reactions. The two-potential formalism is shown to be a convenient method for the separation of long-range (molecular) and short-range (nuclear) dynamics. As specific applications, electron screening effects and muon catalysis in nuclear reactions are investigated. In the case of electron screening in very-low-energy nuclear reactions a method is elaborated for calculation of the enhancement of the astrophysical factor. For muon-catalyzed fusion reactions the sudden approximation is shown to be valid even if the reaction is dominated by a long-lived nuclear resonance.

Role of Coulomb interaction in the phase formation of fcc Ce: Correlation matrix renormalization theory

Journal Article Liu, Jun ; Yao, Yongxin ; Zhang, Jianhua ; ... - Physical Review B

The effect of electronic Coulomb interaction on the phase formation of fcc Ce lattice is investigated by full ab initio calculations without adjustable Coulomb U and J parameters using the Gutzwiller wavefunction-based correlation matrix renormalization theory (CMRT). Its total energy and pressure as a function of volume agree reasonably well with existing DFT+Gutzwiller calculations and experiments, indicating correct capture of electronic correlation and screening effects within the CMRT formalism. Here, a stable phase is found in line with the experimental α-Ce phase, and a lurking phase is identified supposedly linked with the experimental γ-Ce phase. A criterion based on themore »« less

Atomic screening and intersite Coulomb repulsion in strongly correlated systems

Journal Article Meinders, M B.J. ; van den Brink, J ; Lorenzana, J ; ... - Physical Review, B: Condensed Matter

We consider the influence of a nearest-neighbor Coulomb interaction in an extended Hubbard model and introduce an interaction term which simulates atomic polarizabilities. The inclusion of atomic polarizabilities in the model has the effect of screening the on-site Coulomb interaction for charged excitations, unlike a neighbor Coulomb interaction which reduces energies of neutral local excitations, leaving the conductivity gap unchanged. This is supported by an exact diagonalization study on small, mainly one-dimensional, extended Mott-Hubbard systems. For large {ital V}, the system undergoes a phase transition from a spin-density wave (SDW) to a charge-density wave (CDW). It is shown that themore »« less
