Probing Near-Threshold -Wave Components in Heavy Nuclei via Coulomb-Assisted Neutron Transfer
Yuki Nakanishi, Junki Tanaka, Atsushi Tamii +1
We propose a method to probe weakly bound s-wave neutron components near the neutron emission threshold in heavy nuclei using Coulomb-assisted neutron transfer reactions. Weakly bo…

Complex-valued in-medium potential between heavy impurities in ultracold atoms
Yukinao Akamatsu, Shimpei Endo, Keisuke Fujii +1
We formulate the induced potential in a finite temperature cold atomic medium between two heavy impurities, or polarons, which is shown to be \textit{complex-valued} in general. Th…
