Correlation effects on the Fermi surface of the two-dimensional Hubbard model
Effects of electron correlation on the Fermi surface is investigated for the
two-dimensional Hubbard model by the quantum Monte Carlo method. At first, an
infinitesimal doping from the half filling is focused on and the momentum
dependent charge susceptibility is calculated
at a finite temperature. At the temperature , it shows
peak structure at on the Fermi surface (line). It is
consistent with the mean-field prediction of the d-wave pairing state or the
staggerd flux state. This momentum dependent structure disappears at the high
temperature . After summarizing the results of the half filling
case, we also discuss the effects of the doping on the momentum dependent
charge susceptibility. The anisotropic structure at half filling fades out with
sufficient doping.Comment: 6 pages, 3 figures; proceedings of ISSP
Ingredients of nuclear matrix element for two-neutrino double-beta decay of 48Ca
Large-scale shell model calculations including two major shells are carried
out, and the ingredients of nuclear matrix element for two-neutrino double beta
decay are investigated. Based on the comparison between the shell model
calculations accounting only for one major shell (-shell) and those for two
major shells (-shell), the effect due to the excitation across the two
major shells is quantitatively evaluated.Comment: To appear in J. Phys. Soc. Conf. Proc. (ARIS2014); for ver.2, Fig.1
