研究了富勒烯大分子的电子和弹性性质。在（2+1）维中，低能级由Dirac方程描述，分子内模由弹性理论给出。电子和声子之间的耦合也可以用一种简单的方法来写。的离子的量子动力学修改的外观的非平凡的Berry的阶段。还研究了椭圆形和圆柱形富勒烯以及负曲率极小表面的定性特征。
The electronic and elastic properties of large fullerene molecules are studied. The low-lying electronic levels are described by the Dirac equations in (2+1) dimensions, and the intramolecular modes are given by the theory of elasticity. Coupling between electrons and phonons can also be written in a simple way. The quantum dynamics of the ions is modified by the appearance of nontrivial Berry's phases. The qualitative features of fullerenes with elliptical and cylindrical geometries, and minimal surfaces with negative curvature are also studied.
