Craig C. Martens of the University of California-Irvine is supported by an award from the Theoretical and Computational Chemistry program for research to develop theoretical and computational methodology for the investigation of coherent quantum mechanical processes in many-body systems. The research is taking a mixed classical-quantum approach to generalizing classical molecular dynamics for systems with multiple quantum states and is based on a semiclassical approximation to the multistate quantum mechanical Liouville equation in the Wigner representation. Martens is applying these methods to several applications including the study of electronic excitations using shaped ultrafast pulses, an investigation of the semiclassical dynamics of quantum coherence from a dynamical systems perspective, and a study of the creation of possible quantum coherences from classical system bath modes. The work is having a broader impact through the training of students in modern theoretical and computational methods.

加利福尼亚大学 - 艾尔文大学的Craig C. Martens获得了理论和计算化学计划的奖项，用于开发理论和计算方法，以研究多体系统中相干量子机械过程的研究。 这项研究正在采用一种混合经典量子方法来概括具有多个量子状态的系统的经典分子动力学，并且基于Wigner表示中多种量子量子机械liouville方程的半经典近似。 Martens将这些方法应用于几种应用，包括使用形状的超快脉冲研究电子激发，从动力学系统角度研究量子相干性的半经典动力学，以及研究从经典系统播放模式创建可能的量子相干性的研究。 这项工作是通过在现代理论和计算方法中培训学生的培训，从而产生更大的影响。
