    The role of the Heisenberg principle in Constrained Molecular Dynamics model

    K. Wang · A. Bonasera · H. Zheng · G. Q. Zhang · Y. G. Ma · W. Q. Shen

    We implement the Heisenberg principle into the Constrained Molecular Dynamics (CoMD) model with a similar approach to the Pauli principle using the one-body occupation probability . Results of the modified and the original model with comparisons to data are given. The binding energies and the radii of light nuclei obtained with the modified model are more consistent to the experimental data than the original one. The collision term and the density distribution are tested through a comparison to p+C elastic scattering data. Some simulations for fragmentation and superheavy nuclei production are also discussed.

    Ernest Henley's Isospin and the Ensuing Progress

    Gerald A. Miller🇺🇸

    Ernest Henley's contributions to understanding isospin symmetry and the experimental and theoretical progress that followed are reviewed. Many experimentalists and theorists worked to bring Ernest's early vision of the subject to fruition. This progress and wide-ranging impact is described.

    Kinetic approach to polarization-vorticity coupling and hydrodynamics with spin

    Avdhesh Kumar

    Recently introduced equilibrium Wigner functions for spin-one-half particles are used in the semiclassical kinetic equations to study the relation between spin polarization and vorticity. It is found, in particular, that such a framework does not necessarily imply that the thermal-vorticity and spin polarization tensors are equal. Subsequently, a procedure to formulate the hydrodynamic framework for particles with spin-one-half, based on the semiclassical expansion, is outlined.

    Supplemental note for "Two-fermion emission from spin-singlet and triplet resonances in one dimension"

    Tomohiro Oishi🇭🇷

    Time-dependent calculation has been a suitable method to investigate the quantum dynamical processes. In Ref. [1] = [T. Oishi et al., J. of Phys. G 45, 105101 (2018)], we applied this method to the one-dimensional two-fermion tunneling in the nuclear-physics scale. Beside the specific results presented therein, some basic formalism and methods, which can be helpful for further discussions and developments to investigate time-dependent quantum systems, have been awaiting our description. This note is devoted to describe those supplemental contents. We do not limit the story to the nuclear physics, but keep it applicable to other scales and/or targets.

    An introduction to Bootstrap for nuclear physics

    A. Pastore

    This guide aims at providing a general introduction to bootstrap methods. By using simple examples taken from nuclear physics, I discuss how such a method can be used to quantify error bars of an estimator. I also investigate the use of bootstrap to estimate parameters of a simple liquid drop model. In particular, I investigate how the method compares with standard techniques based on likelihood estimator and how to take into account correlations to better evaluate confidence interval of parameters.
