| 中文摘要 | By studying a spinless fermion system, which under some conditions is equivalent to a XXZ spin-1/2 Heisenberg chain coupled to a spin-1/2 magnetic impurity, we introduce a new method which can be used systematically to find the stable infrared critical fixed point and corresponding effective action of the system. Moreover, near this stable infrared critical fixed point, in terms of the corresponding effective action, we show that the phase factor field appearing in the hybridization amplitude plays a key role in forming a possible bound state near the impurity site. This result can be tested in future numerical simulations. |
