我们首先证明了引力相互作用的有效非相对论理论,大质量整数自旋场(特别是自旋-$0$,$1$和$2$)是由$2s+1$分量Schr\ \ {o}丁格尔-泊松作用描述的,其中$s$是场的自旋。然后,我们用同极化平面波在非相对论理论中构造了$s+1$个不同的、有引力支持的孤子。这样的孤子是极端极化的,具有宏观上大的自旋,但没有轨道角动量。这些$ 5 +1$孤子形成一个基集,从中可以构造出部分极化孤子。所有这样的孤子都是基态,具有球对称的能量密度,但没有场构型。讨论了如何区分高自旋场中的孤子与标量孤子,以及它们的潜在引力和非引力探测。
We first show that the effective non-relativistic theory of gravitationally interacting, massive integer-spin fields (spin-$0$, $1$, and $2$ in particular) is described by a $2s+1$ component Schr\"{o}dinger-Poisson action, where $s$ is the spin of the field. We then construct $s+1$ distinct, gravitationally supported solitons in this non-relativistic theory from identically polarized plane waves. Such solitons are extremally polarized, with macroscopically large spin, but no orbital angular momentum. These $s+1$ solitons form a basis set, out of which partially polarized solitons can be constructed. All such solitons are ground states, have a spherically symmetric energy density but not field configurations. We discuss how solitons in higher-spin fields can be distinguished from scalar solitons, and potential gravitational and non-gravitational probes of them.
