      1967年出生于浙江,1989年毕业于复旦大学物理系,1994年在纽约大学物理系获得博士学位。先后在纽约大学,芝加哥大学从事博士后研究; 1997年应聘到新加坡国立大学计算科学系任教,2000年升为副教授; 2004年被聘为大连化学物理研究所研究员。先后获新加坡杰出青年科学家奖(2000),新加坡国家科学奖(2003),国家自然科学基金海外及港澳青年学者合作研究基金(2003), 国家杰出青年科学基金(2006)。张东辉研究员致力于发展有效的理论与计算新方法研究发生在气相、团簇、固体表面、以及生物分子中的原子分子运动、反应、能量转移等动力学问题。
      主要研究方向:
      1. 气相反应动力学
      发展和运用有效的量子动力学方法研究气相分子反应动力学。对于小体系问题,如H+H2, F+H2,O+H2, H+O2等三原子,H2+OH, H+H2O, OH+CO等四原子反应,运用含时波包法进行严格的态-态水平的全维量子动力学研究,并注重这些反应中的非绝热现象。对于如H+CH4, Cl+CH4这些多于四原子的反应体系,注重于建立有效的减维模型,力求在现有的计算机条件下进行最精确的计算。注重与实验的紧密结合,以探索化学反应中的新现象,从分子水平上认识化学反应的过程和机理。
      2. 复杂体现的量子动力学
      为研究更复杂的量子动力学问题,如质子氢原子在生物分子中的转移,氢原子在固体表面以及固体中的扩散,分子在固体表面的吸附与离解等,致力于发展和运用含时波包法,过渡态波包法,以及连续组态含时自洽场方法,并注重开发与利用基于MPI架构的大规模并行计算方法。
      3.高精度势能面的构造
      高精度势能面是从第一性原理精确研究分子反应动力学的基础。为精确研究多原子分子体系的动力学问题,通过高精度的从头算构造精确的多原子分子体系的势能面。运用有效的势能面构造法构造一批高精度势能面: 包括在燃烧过程或大气过程中的重要的基元反应,如F+H2, O+O2, H2+OH, OH+CO, H+CH4, Cl+CH4等; 以及原子分子与表面的作用体系,如氢原子与固体表面以及固体的相互作用, H2, CH4在金属表面的吸附和解离,水在金属氧化物表面的吸附。对于三原子体系,一般采用函数拟合法或样条插值法;对于多原子分子体系以及分子与表面作用体系,应用由Collins等发展的高维插值法。
Prof. Dong Hui Zhang graduated from Fudan University of China in 1985, and received his Ph. D. from New York University, USA in 1994. He had worked as a postdoctoral research associate in New York University and The University of Chicago. He started his professional career at Department of Computational Science, National University of Singapore in 1997, first as an Assistant Professor, and was prompted to Associate Professor with tenure in 2000. Since 2004 he has been a Professor in Dalian Institute of Chemical Physics.
Research Interests:
Prof. Zhang’s research is aimed to develop efficient theoretical and computational methodologies to study quantum molecular dynamics in various systems. For small (3 or 4 atom) molecular systems, we pursue exact quantum mechanical scattering calculations to obtain all interesting information for chemical reactions, from the most detailed state-to-state reactive scattering cross sections to thermal rate constants. For chemical reactions involving more than four atoms, we are interested in developing reduced dimensionality models to achieve the most accurate dynamical results under current computer technology. To treat more complex molecular ystems, Prof. Zhang’s group is pursuing use of the continuous-configuration time dependent self-consistent field (CC-TDSCF) method in combination with the transition state wave packet method. We are also interested in constructing highly accurate potential energy surfaces in order to apply the accurate dynamics method we developed to some specific systems of chemical interesting.
