    Intertwined quantum phase transitions in odd-mass Nb isotopes

    A. Leviatan🇮🇱 · N. Gavrielov🇫🇷 · F. Iachello🇺🇸

    A detailed analysis of odd-mass Nb isotopes, in the framework of the interacting boson-fermion model with configuration mixing, discloses the effects of an abrupt crossing of states in normal and intruder configurations (Type~II QPT), on top of which superimposed a gradual evolution from spherical- to deformed-core shapes within the intruder configuration (Type~I QPT). The pronounced presence of both types of QPTs demonstrates, for the first time, the occurrence of intertwined QPTs in odd-mass nuclei.

    pynucastro 2.1: an update on the development of a python library for nuclear astrophysics

    Alexander Smith Clark · Eric T. Johnson · Zhi Chen · Kiran Eiden · Michael Zingale · Brendan Boyd · Parker T. Johnson · Luis Rangel DaCosta

    pynucastro is a python library that provides visualization and analyze techniques to classify, construct, and evaluate nuclear reaction rates and networks. It provides tools that allow users to determine the importance of each rate in the network, based on a specified list of thermodynamic properties. Additionally, pynucastro can output a network in C++ or python for use in simulation codes, include the AMReX-Astrophysics simulation suite. We describe the changes in pynucastro since the last major release, including new capabilities that allow users to generate reduced networks and thermodynamic tables for conditions in nuclear statistical equilibrium.
