费米子-涡旋系统的中隙谱

Midgap spectrum of the fermion-vortex system

B. Seradjeh

摘要:

我研究了两维空间中费米子-涡旋系统的中能隙谱。除了Jackiw和Rossi发现的零模外,还建立了束缚态的存在。对于一个单量子化的涡旋,我提出了完整的解析解的广义拉盖尔多项式在相反的限制消失和大涡核尺寸。有无限多的这样的束缚态,当平方时,其谱分别由库仑势和各向同性谐振子给出。可能的实验签名,这一频谱中的凝聚态实现的系统指出。

英文摘要:

I study the midgap spectrum of the fermion-vortex system in two spatial dimensions. The existence of bound states, in addition to the zero modes found by Jackiw and Rossi, is established. For a singly quantized vortex, I present complete analytical solutions in terms of generalized Laguerre polynomials in the opposite limits of vanishing and large vortex core size. There is an infinite number of such bound states, with a spectrum that is, when squared, given by, respectively, the Coulomb potential and the isotropic harmonic oscillator. Possible experimental signatures of this spectrum in condensed-matter realizations of the system are pointed out.
