论文摘要
在超流体暗物质(SFDM)中,声子字段起着双重作用:它带有超级流体的能量密度,并介导类似于mond的声子力。我们表明,这两个角色在银河尺度上相互张紧:蒙克状的声子力是张力的,平衡中的超氟和明显的超级流体能量密度处于张力。为了避免这些紧张局势,我们提出了一个模型,其中两个角色在两个不同的字段之间分配。这也使我们能够以比标准SFDM更优雅的方式解决稳定问题。我们认为,需要重新审视银河系超流体核心大小的标准估计。
In superfluid dark matter (SFDM), the phonon field plays a double role: It carries the superfluid's energy density and it mediates the MOND-like phonon force. We show that these two roles are in tension with each other on galactic scales: A MOND-like phonon force is in tension with a superfluid in equilibrium and with a significant superfluid energy density. To avoid these tensions, we propose a model where the two roles are split between two different fields. This also allows us to solve a stability problem in a more elegant way than standard SFDM. We argue that the standard estimates for the size of a galaxy's superfluid core need to be revisited.
