Erratum to: “Spin orbit splitting and the Tensor Component of the Skyrme interaction” [Phys. Lett. B 646 (2007) 227]
Physics Letters B, 2008Co-Authors: G Colo, H Sagawa, S Fracasso, P F BortignonAbstract:We study the role of the Tensor term of the Skyrme effective interactions on the spin-orbit splittings in the N=82 isotones and Z=50 isotopes. The different role of the triplet-even and triplet-odd Tensor forces is pointed out by analyzing the spin-orbit splittings in these nuclei. The experimental isospin dependence of these splittings cannot be described by Hartree-Fock calculations employing the usual Skyrme parametrizations, but is very well accounted for when the Tensor interaction is introduced. The capability of the Skyrme forces to reproduce binding energies and charge radii in heavy nuclei is not destroyed by the introduction of the Tensor term. Finally, we also discuss the effect of the Tensor force on the centroid of the Gamow-Teller states.Comment: Submitted to Phys. Lett.

comment on breakdown of the Tensor Component in the skyrme energy density functional
arXiv: Nuclear Theory, 2020Co-Authors: H Sagawa, G Colo, Ligang CaoAbstract:In a recent paper [Phys. Rev. C 101, 014305 (2020)], Dong and Shang claim that the Skyrme original Tensor interaction is invalid. Their conclusion is based on the misconception that the Fourier transform of Tensor interaction is difficult or even impossible, so that the Skrme-type Tensor interaction was introduced in an unreasonable way. We disagree on their claim. In this note, we show that one can easily get the Skyrme force in momentum space by Fourier transformation if one starts from a general central, spin-orbit or Tensor interaction with a radial dependence.

Robust Low-Rank Tensor Ring Completion
'Institute of Electrical and Electronics Engineers (IEEE)', 2020Co-Authors: Huang Huyan, Liu Yipeng, Ce ZhuAbstract:Low-rank Tensor completion recovers missing entries based on different Tensor decompositions. Due to its outstanding performance in exploiting some higher-order data structure, low rank Tensor ring has been applied in Tensor completion. To further deal with its sensitivity to sparse Component as it does in Tensor principle Component analysis, we propose robust Tensor ring completion (RTRC), which separates latent low-rank Tensor Component from sparse Component with limited number of measurements. The low rank Tensor Component is constrained by the weighted sum of nuclear norms of its balanced unfoldings, while the sparse Component is regularized by its l1 norm. We analyze the RTRC model and gives the exact recovery guarantee. The alternating direction method of multipliers is used to divide the problem into several sub-problems with fast solutions. In numerical experiments, we verify the recovery condition of the proposed method on synthetic data, and show the proposed method outperforms the state-of-the-art ones in terms of both accuracy and computational complexity in a number of real-world data based tasks, i.e., light-field image recovery, shadow removal in face images, and background extraction in color video
