Researchers Develop First Angular Momentum Conserved Transport Model for Ultra-relativistic Many-body Systems

Dr. LIU Shuai at Quark Matter Research Center, Institute of Modern Physics (IMP) of the Chinese Academy of Sciences, together with researchers at Texas A&M University and Laboratori Nazionali del Sud, have developed the first angular momentum conserved transport model for ultra-relativistic many-body systems and applied it to study the spin physics in heavy-ion collisions. Transport model is an important theoretical tool used in non-equilibrium many-body systems to describe the evolution of particles’ microscopic states such as momentum, position and spin. Boltzmann...

Scientists Report Heavy Ion Transfer in Charged vdW Cluster for the First Time

It has been recognized that proton transfer is crucial to many chemical and biological processes. As these processes are known to be relevant to biophysics and radiation therapy, a question arises whether a massive ion could be transferred in biochemical processes and lead to fragmentation. Published in Nature Communications on June 12th, a new study helps address the above questions.Since the discovery of the double helix form of DNA and the hypothesis of DNA mutation induced by proton transfer more than 50 years ago, it has been recognized that proton transfer is crucial to m...

Researchers Apply Gamow Shell Model to Analyze Two-neutron Halo Structure of 31F

Researchers from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences and Peking University lately applied the Gamow shell model to analyze the two-neutron halo structure of 31F. A powerful tool to describe halo nuclei is the Gamow shell model (GSM), which is an extension of the standard shell model of well-bound nuclei. According to GSM calculations, 31F is a two-neutron ha...Researchers from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences and Peking University lately applied the Gamow shell model to analyze the two-neutron halo structure of 31F...

A New Measurement of Charge-Exchange Reaction Helps Us Understand Core-Collapse Supernovae

Some massive stars end their life as core-collapse supernovae (CCSNe), which is the most energetic and mysterious event in the universe. A large amounts of energy will be released during CCSNe and the whole galaxy can be lighted up. Decades of efforts have been devoted to understanding CCSNe while some open questions still remain. One of the important physical inputs in CCSNe simulations is the...Researchers from many institutions, including the Institute of Modern Physics of the Chinese Academy of Sciences, have lately made progress in the study of the electron-capture rates of the 93Nb by...
