非相对论流体模型的场相关对称性

Field-dependent symmetries of a non-relativistic fluid model

M. Hassaïne, P. A. Horváthy

摘要:

正如Bordemann、Hoppe和Jevicki所发现的那样,一种与膜和部分子有关的无旋等熵流体的非相对论模型具有庞加莱对称性。Bazeia和Jackiw将这种动力学对称性与时空中一种新型的“场依赖”作用联系起来。Duval等人的“Kaluza-Klein型”框架被用来解释这些对称性的起源,并导出相关的守恒量。在非相互作用的情况下,对称性扩展到整个共形群。

英文摘要:

As found by Bordemann and Hoppe and by Jevicki, a certain non-relativistic model of an irrotational and isentropic fluid, related to membranes and to partons, admits a Poincaré symmetry. Bazeia and Jackiw associate this dynamical symmetry to a novel type of ``field dependent'' action on space-time. The ``Kaluza-Klein type'' framework of Duval et al. is used to explain the origin of these symmetries and to derive the associated conserved quantities. In the non-interacting case, the symmetry extends to the entire conformal group.
