J. J. Sławianowski, V. Kovalchuk, A. Martens, B. Gołubowska, E. E. Rożko

摘要:

讨论了在Weyl、Wigner、Moyal和Ville意义下的量子力学相空间形式的一些几何问题。我们分析了这种形式主义和几何的Galilei组,经典的动量映射,酉射影表示群的理论,和理论的群代数之间的关系。随后我们在局部紧阿贝尔群上给出了量子力学的一些推广。它基于庞特里亚金对偶性。指出了晶格量子动力学中的某些物理方面,包括“Umklapp-Prozessen”现象。

英文摘要:

Discussed are some geometric aspects of the phase space formalism in quantum mechanics in the sense of Weyl, Wigner, Moyal and Ville. We analyze the relationship between this formalism and geometry of the Galilei group, classical momentum mapping, theory of unitary projective representations of groups, and theory of groups algebras. Later on we present some generalization to quantum mechanics on locally compact Abelian groups. It is based on Pontryagin duality. Indicated are certain physical aspects in quantum dynamics of crystal lattices, including the phenomenon of "Umklapp-Prozessen"
