I obtained Bachelor degree in Physics in 2004 from Nankai University, China, and received my Ph.D. degree in Nuclear and Particle Physics in 2009 at Peking University. In 2011, I became a post-doctoral fellow at the Universite Libre de Bruxelles , Belgium and jointed the University of North Carolina at Chapel Hill as a Postdoctoral Research Associate in 2015.
In 2009 I obtained a tenure-tracked professor position in Southwest University of China and was promoted as a tenured professor in the same university in 2012. In the Southwest University, I built up a theoretical group of young researchers interested in nuclear physics and nuclear astrophysics. In 2013, I joined the Department of Physics at the Tohoku University in Japan as an Assistant Professor, a contracted two-year position.
I have been in charge of two grants sponsored by the National Natural Science Foundation of China (NSFC) . These two grants supported the research activities of me and our students in China on the spectroscopy of exotic nuclei and hypernuclei starting from 2009 to 2014. A new grant was recently approved by the NSFC in 2015 to support our researches in China on the structure and decay properties of odd nuclei starting from 2016 to 2019.
My researches are focused on the properties of atomic nuclei and hypernuclei, as well as some related topics in astrophysics and particle physics. Here are several topics that we have worked on in the past years:
  • Multi-reference covariant density functional theory for nuclear low-lying states.
  • Microscopic study of shape coexistence and shape transition in atomic nuclei.
  • Relativistic description of nuclear matrix elements for neutrinoless double beta decay.
  • Beyond mean-field approaches for hypernuclear spectroscopy.
  • Towards microscopic modeling of heavy-ion fusion reactions.
    Major collaborators on these topics:

    Prof. Jie Meng from Peking University
    Prof. Peter Ring from Technical University of Munich
    Prof. Kouichi Hagino and Hua Mei from Tohoku University

    Ongoing Project of Neutrinoless Double Beta Decay
    Neutrinoless DBD is a second-order weak process in which a nucleus decays to the neighboring nucleus by emitting only two electrons. At the nucleon level, it corresponds to two neutrons simutaneously convert into two protons. This process plays a crucial role by probing that neutrinos are Majorana particles, determining the absolute neutrinos mass and explorimg possible existing CP-phases associated with the Majorana character, which finally might have an impact on the baryon asymmetry in the Universe via leptogenesis .

    According to the mechanism of exchange light Majorana neutrinos, the half-life of neutrinoless DBD can be factorized as a multiplication of three quantities: the kinematical phase space factor, the effective Majorana neutrino mass and the nuclear matrix element (NME). Since the phase space factor can be calculated precisely, a reliable calculation of the NME is highly desired to extract the effective neutrino mass from the measurement of the decay rate.

    Our ongoing project is to achieve an ab-initio calculation of the NMEs for the neutrinoless DBD using the so-called In-medium SRG method with a RG evolved chiral force. The multi-reference wave functions from the GCM calculation are adopted as the reference states. Many kinds of correlations are included in the groun-state wave functions. However, there are many challenges to overcome.
