有效场论与Z_k亚费米子分数量子Hall态的投影构造

Effective Field Theory and Projective Construction for the Z_k Parafermion Fractional Quantum Hall States

Maissam Barkeshli, Xiao-Gang Wen

摘要:

投影构造是一种强有力的方法来推导非阿贝尔分数量子霍尔(HHH)态的体和边场论,并产生一个更简单的整数量子霍尔态的非阿贝尔HHH态的理解。本文给出了在填充分数ν= k/(kM+2)处的Z_k仿费米子(Laughlin/Moore-Read/Read-Rezayi)→ H态的投影构造.这使我们能够导出这些拓扑相的体低能有效场论,它是一个具有U(M)\times Sp(2 k)规范场的1级Chern-Simons理论。这种方法也有助于我们理解整数量子霍尔态的空穴的非阿贝尔准空穴。

英文摘要:

The projective construction is a powerful approach to deriving the bulk and edge field theories of non-Abelian fractional quantum Hall (FQH) states and yields an understanding of non-Abelian FQH states in terms of the simpler integer quantum Hall states. Here we show how to apply the projective construction to the Z_k parafermion (Laughlin/Moore-Read/Read-Rezayi) FQH states, which occur at filling fraction ν= k/(kM+2). This allows us to derive the bulk low energy effective field theory for these topological phases, which is found to be a Chern-Simons theory at level 1 with a U(M) \times Sp(2k) gauge field. This approach also helps us understand the non-Abelian quasiholes in terms of holes of the integer quantum Hall states.
