拓扑超流体

Topological Superfluids

G. E. Volovik

摘要:

$^3$ He的超流相具有多种拓扑面。这些超流体包含各种拓扑缺陷和纹理。这些超流体的动量空间拓扑也是非平凡的,以及组合(${\bf p},{\bf r})$)相空间中的拓扑,从而产生了拓扑保护的狄拉克、外尔和马约拉纳费米子,它们生活在拓扑物体的表面和内部。非平凡拓扑导致了不同类型的反常,这些反常在许多不同的方向上扩展了Landau-Khalatninkov超流理论。

英文摘要:

There are many topological faces of the superfluid phases of $^3$He. These superfluids contain various topological defects and textures. The momentum space topology of these superfluids is also nontrivial, as well as the topology in the combined (${\bf p},{\bf r})$ phase space, giving rise to topologically protected Dirac, Weyl and Majorana fermions living in bulk, on the surface and within the topological objects. The nontrivial topology lead to different types of anomalies, which extended in many different directions the Landau-Khalatninkov theory of superfluidity.
