SUMMARY:National Superconducting Cyclotron Laboratory Seminar
DESCRIPTION:
 Xilin Zhang from Ohio State University willbe 
 presenting "Ab initio calculations of low-energy 
 nuclear scattering using confining potential 
 traps."\n
 \n
 Ab initio nuclear structure calculations 
 that compute nuclear static properties 
 based on underlying NN interactions and 
 three-nucleon forces have now progressed to studying 
 medium-mass nuclei. However, first-principle 
 calculations for nuclear scattering/reactions 
 are still limited to light systems. 
 A method suitable for heavier nuclei would be 
 very valuable in studying scattering/reactions 
 with astrophysical relevance and for the success 
 of the coming FRIB program that will focus 
 on unstable nuclei near drip lines. In this 
 talk, I will present my recent development 
 of such a method (2004.13575 and 1905.05275). 
 It is similar in spirit to the so-called Luscher 
 method, used in Lattice QCD for computing 
 hadronic scattering. The key idea is a computational 
 experiment: realizing the trapping 
 of nucleus-nucleus or nucleus-nucleon systems 
 in harmonic potential well within the ab initio 
 spectrum calculations, and then extracting 
 scattering information from the output. I 
 will discuss the formalism and report encouraging 
 results from my collaboration with ab initio 
 groups on computing neutron--alpha and 
 neutron--Oxygen-24 scattering phase shifts. I 
 will also discuss ways to generalize this approach 
 to the case of inelastic reactions and 
 three-cluster systems, including the one opened 
 up by our recently developed emulator (2007.03635) 
 for scattering.\n\n
