关于Lévy-Leblond-Newton方程及其对称性的几何观点

On the Lévy-Leblond-Newton equation and its symmetries: a geometric view

Serge Lazzarini, Loïc Marsot

摘要:

在$(n+1)$维Newton-Cartan(NC)时空上的Bargmann结构框架下,重新表述了具有引力自相互作用的非相对论费米子的Lévy-Leblond-Newton(LLN)方程.在[21]中引入的薛定谔-牛顿(SN)群是SN方程的最大不变性群,它也是保耦合Lévy-Leblond方程和NC引力场方程的共形Bargmann自同构群。在巴格曼几何的LLN方程的推广,以及提供。给出了SN群在四分量旋量上的正则投射酉表示。特别地,当限制为膨胀时,动力学指数$z=(n+2)/3$的值恢复为先前在[21]中针对SN方程导出的。随后,守恒量相关的(广义)LLN方程也展出。

英文摘要:

The Lévy-Leblond-Newton (LLN) equation for non-relativistic fermions with a gravitational self-interaction is reformulated within the framework of a Bargmann structure over a $(n+1)$-dimensional Newton-Cartan (NC) spacetime. The Schrödinger-Newton (SN) group, introduced in [21] as the maximal group of invariance of the SN equation, turns out to be also the group of conformal Bargmann automorphisms preserving the coupled Lévy-Leblond and NC gravitational field equations. Within the Bargmann geometry a generalization of the LLN equation is provided as well. The canonical projective unitary representation of the SN group on 4-component spinors is also presented. In particular, when restricted to dilations, the value of the dynamical exponent $z=(n+2)/3$ is recovered as previously derived in [21] for the SN equation. Subsequently, conserved quantities associated to the (generalized) LLN equation are also exhibited.
