    The maximal degree of the Khovanov homology of a cable link

    Full text link
    In this paper, we study the Khovanov homology of cable links. We first estimate the maximal homological degree term of the Khovanov homology of the (2k+12k+1, (2k+1)n(2k+1)n)-torus link and give a lower bound of its homological thickness. Specifically, we show that the homological thickness of the (2k+12k+1, (2k+1)n(2k+1)n)-torus link is greater than or equal to k2n+2k^{2}n+2. Next, we study the maximal homological degree of the Khovanov homology of the (pp, pnpn)-cabling of any knot with sufficiently large nn. Furthermore, we compute the maximal homological degree term of the Khovanov homology of such a link with even pp. As an application we compute the Khovanov homology and the Rasmussen invariant of a twisted Whitehead double of any knot with sufficiently many twists.Comment: 40 pages, 26 figures, I shorten some proof

    Realistic description of the rotational bands in rare earth nuclei by angular-momentum-projected multi-cranked configuration-mixing method

    Full text link
    Recently we have proposed a reliable method to describe the rotational band in a fully microscopic manner. The method has recourse to the configuration-mixing of several cranked mean-field wave functions after the angular-momentum-projection. By applying the method with the Gogny D1S force as an effective interaction, we investigate the moments of inertia of the ground state rotational bands in a number of selected nuclei in the rare earth region. As another application we try to describe, for the first time, the two-neutron aligned band in 164^{164}Er, which crosses the ground state band and becomes the yrast states at higher spins. Fairly good overall agreements with the experimental data are achieved; for nuclei, where the pairing correlations are properly described, the agreements are excellent. This confirms that the previously proposed method is really useful for study of the nuclear rotational motion
