    Chiral Magnetic Effect in Heavy Ion Collisions: The Present and Future

    Dmitri E. Kharzeev🇺🇸 · Jinfeng Liao🇺🇸 · Prithwish Tribedy🇺🇸

    The chiral magnetic effect (CME) is a collective quantum phenomenon that arises from the interplay between gauge field topology and fermion chiral anomaly, encompassing a wide range of physical systems from semimetals to quark-gluon plasma. This review, with a focus on CME and related effects in heavy ion collisions, aims to provide an introductory discussion on its conceptual foundation and measurement methodology, a timely update on the present status in terms of experimental findings and theoretical progress, as well as an outlook into the open problems and future developments.

    Electromagnetic observables of open-shell nuclei from coupled-cluster theory

    Francesca Bonaiti · Sonia Bacca · Gaute Hagen · Gustav R. Jansen

    We develop a new method to describe electromagnetic observables of open-shell nuclei with two nucleons outside a closed shell. This approach combines the equation-of-motion coupled-cluster method for such systems and the Lorentz integral transform technique, expanding the applicability of coupled-cluster theory for these properties beyond closed-shell nuclei. To validate this new approach, we compute the non-energy-weighted dipole sum rule and the dipole polarizability of O in both the closed-shell and the new equation-of-motion coupled-cluster frameworks, finding agreement within error bars. We then analyze the evolution of the dipole polarizability along the oxygen and calcium isotopic chains. Our predictions agree well with available experimental data and other available theoretical calculations for the closed-shell O and the open-shell O. In the calcium isotopes, we observe that our dipole polarizability predictions for open-shell nuclei are lower than those of closed-shell nuclei. Our predictions for O and Ca will motivate future experimental studies at the dripline.
