Fourth International Conference on Quasicrystals, St Louis, Missouri, May 31-June 5, 1992

这是第四届准晶体国际会议， 这是第一次在美国举行。 拟讨论的议题 包括理解的几何形状和化学装饰的 准晶体结构，详细的结构研究大， 单准晶的形成、稳定性和物理性质 准晶体的性质 准晶体的新领域 研究涵盖，包括衍射和动力学的 合成的非周期性结构。 %%% 虽然在许多方面与晶体相似，但准晶具有 可能导致新行为的重要差异。 部分车型 表明了奇异的电子特性 异常磁行为 可能是由于某些原子的极高对称性 网站.

This is the fourth international conference on quasicrystals and the first to be held in the United States. Topics to be discussed include understanding the geometry and chemical decorations of the quasicrystal structures, detailed structural studies on large, single quasicrystals, and the formation, stability, and physical properties of quasicrystals. New frontiers in quasicrystal research are covered, including diffraction and dynamics of synthetic non-periodic structures. %%% While similar to crystals in many respects, quasicrystals have important differences that may lead to novel behavior. Some models suggest exotic electronic properties. Unusual magnetic behavior may result from the extremely high symmetry about certain atomic sites.
