圆锥交叉点附近的反常分子动力学

Anomalous molecular dynamics in the vicinity of conical intersections

Jonas Larson, Elham Nour Ghassemi, Asa Larson

摘要:

分子电子势面之间的圆锥相交极大地影响了分子的各种性质。分子规范理论能够解释许多来自圆锥相交物理学的这些经常意想不到的现象。在这里,我们给出了一个例子的Exe Jahn-Teller模型的范式,这不允许一个简单的解释,在标准的分子规范理论的反常动力学。通过引入一个双规范理论,我们解开这个令人惊讶的行为,确定它与一个内在的自旋霍尔效应。因此,这项工作将凝聚态理论的知识与分子振动联系起来。此外,通过从头计算的结果,以及证明出现在现实的系统,如Li 3分子。

英文摘要:

Conical intersections between molecular electronic potential surfaces greatly affect various properties of the molecule. Molecular gauge theory is capable of explaining many of these often unexpected phenomena deriving from the physics of the conical intersection. Here we give an example of anomalous dynamics in the paradigm of the Exe Jahn-Teller model, which does not allow a simple explenation in terms of standard molecular gauge theory. By introducing a dual gauge theory, we unwind this surprising behavior by identifying it with an intrinsic spin Hall effect. Thus, this work link knowledge of condensed matter theories with molecular vibrations. Furthermore, via ab initio calculations the findings are as well demonstrated to appear in realistic systems such as the Li3 molecule.
