Chun TangChun joined HiPSEC since 2006 first as a visiting PhD student, then a post-doc in 2010 after graduation. He moved to University of California Merced as an associate specialist and lecturer in 2012 before coming back to HiPSEC in 2016. His research focuses on computational studies of mechanical and physical properties of nanomaterials under various loading conditions such as high temperature and high strain, he is also interested in designing novel functional devices based on nanomaterials.

My research interest has been focused on studying the transport and magnetic properties (particularly magnetocaloric effect) of Ni-Mn based Heusler alloys under hydrostatic pressure and understanding the quantum phase transition in some f electron systems particularly in Eu system, since so far no Eu system has been found where the magnetic ordering temperature decreases continuously to zero with pressure owing to the increase in the level of hybridization.

My research focus is on the phase transition of solids and their electron, phonon, and ion transport at high temperature and high pressure conditions. Materials of interests include strongly-correlated f-electron materials, superhard materials, iron-based superconductors, thermoelectric materials, and Li-rich superionic materials. With the help of in-house computation facility and petascale supercomputer in Oak Ridge National Lab, I apply and develop novel first-principles DFT and molecular dynamics methods and software packages to understand and predict new material behavior. Currently I am training three graduate students and one undergraduate student on various projects. I have published over 30 peer-reviewed papers and 20 presentations from HiPSEC-NNSA projects.

I study strongly correlated electron behaviours such as heavy fermion behaviour, Kondo volume collapse and valence fluctuation phenomena in rare earth and actinide intermetallic and organometallic compounds. I use x-ray diffraction, x-ray absorption near edge spectroscopy (XANES), resonant x-ray emission spectroscopy (RXES) and physical bulk property measurements at low temperature-high magnetic field and high pressure conditions.
