相对论性流体、超流体、固体和超固体的Wess-Zumino项

Wess-Zumino Terms for Relativistic Fluids, Superfluids, Solids, and Supersolids

Luca V. Delacrétaz, Alberto Nicolis, Riccardo Penco, Rachel A. Rosen

摘要:

我们使用低能量有效作用量的陪集结构,系统地推导出Wess-Zumino(WZ)项的流体和各向同性固体系统在二维,三维和四维时空。我们恢复已知的WZ长期流体在两个维度,以及最近发现的WZ长期流体在三维。我们发现两个新的WZ条款的超固体,以前没有出现在文献中。此外,通过放松某些假设的对称群的流体,我们发现了一些新的WZ条款的流体和不带电荷,在所有的维度。我们没有发现固体和超流体的WZ项。

英文摘要:

We use the coset construction of low-energy effective actions to systematically derive Wess-Zumino (WZ) terms for fluid and isotropic solid systems in two, three and four spacetime dimensions. We recover the known WZ term for fluids in two dimensions as well as the very recently found WZ term for fluids in three dimensions. We find two new WZ terms for supersolids that have not previously appeared in the literature. In addition, by relaxing certain assumptions about the symmetry group of fluids we find a number of new WZ terms for fluids with and without charge, in all dimensions. We find no WZ terms for solids and superfluids.
