D膜中的费米液体
Fermi Liquids from D-Branes
摘要:
我们讨论有限密度配置探测D-膜,在世界体积费米子的存在。为此,我们考虑一个唯象模型的玻色子部门是由DBI行动,其收费部门是纯粹的费米子。在这个模型中,我们证明了一个紧凑的世界体积嵌入的存在,稳定的费米表面上的D膜。在边界QFT中的有限密度态是类费米液体。我们评论的可能性,实现非费米液体在这种设置。
英文摘要:
We discuss finite density configurations on probe D-branes, in the presence of worldvolume fermions. To this end we consider a phenomenological model whose bosonic sector is governed by the DBI action, and whose charged sector is purely fermionic. In this model, we demonstrate the existence of a compact worldvolume embedding, stabilized by a Fermi surface on the D- brane. The finite density state in the boundary QFT is a Fermi-like liquid. We comment on the possibility of realizing non-Fermi liquids in this setup.
