Abstract

The differential cross-section of neutrino interaction with dense and warm electron gasses has been calculated by taking into account the neutrino electromagnetic form factors. The significant effect of electromagnetic properties of neutrino can be found if the neutrino dipole moment, μ ν , is ≥ 5.10-9 μB and neutrino charge radius, Rv, is ≥ 5.10-6 MeV-1. The importance of the retarded correction, detailed balance and Pauli blocking factors is shown and analyzed. Many-body effects on the target matter which are included via random phase approximation (RPA) correlation as well as photon effective mass are also investigated.

Abstract

As an extension of our previous theoretical study, we perform temperature-dependent optical conductivity calculations on La0.7Ca0.3MnO3 over a wide photon-energy range up to ∼22 eV, aiming to capture the metal–insulator transition while preserving the general temperature-dependent profile at higher photon energies. The system is modeled with simple Mn–O coordination via the tight-binding method, where some hopping integrals are considered functions of magnetization. Upon incorporating the static Jahn–Teller effect with Coulomb–Hubbard and magnetic exchange interactions, with the exception of a quantitative difference in the calculated of  K versus the experimental value (260 K) and discrepancies in the mid-energy regime, the results reproduce the qualitative temperature-dependent optical conductivity trends, especially for the low- and high-energy regimes, as observed in the experimental data. This qualitative agreement is achieved by setting the magnetization-dependent hopping parameters for the Mn–O hopping parameters,  and , as , with  eV,  eV,  eV,  eV,  eV, and  eV. The results underscore the importance of correlation effects arising from the interplay of the lattice, charge, and magnetic degrees of freedom in determining the overall profile of the temperature-dependent optical response of manganite, connecting the physics of the high-energy optical response and the transport properties at the dc limit.
