The Wigner isobaric multiplet mass equation (IMME) is the most fundamental prediction in nuclear physics with the concept of isospin. However, it was deduced based on the Wigner-Eckart theorem with the assumption that all charge-violating interactions can be written as tensors of rank two. This should be generalized for a general situation. In addition, the Nolen-Schiffer anomaly is a longstanding historical problem, which is an anomaly because when all the corrections were taken into account, there remained a consistent underestimate of theCoulomb displacement energy by about a few to ten percent. The Coulomb displacement energy—the difference in binding energy between two members of a ...Learn more

Neutron star cooling is a hot topic that connects nuclear physics and astrophysics. The observations combined with theory of neutron star (NS) cooling play a crucial role in achieving the intriguing information of the stellar interior, such as the equation of state, composition, and superfluidity of dense matter. The traditional NS cooling theory is based on the assumption that the stellar structure does not change with time. The validity of such a static description has not yet been confirmed. Learn more
