我们利用匹配渐近方法确定了两个反向传播的强相互作用量子霍尔边缘态的能隙。微观边缘态色散和库仑相互作用被用来精确地约束可积场论的短程行为，从而确定低能谱。我们讨论了我们的结果与Kang等人[Nature 403，59（2000）]的隧道测量的关系。
We use a method of matched asymptotics to determine the energy gap of two counter-propagating, strongly interacting quantum Hall edge states. The microscopic edge state dispersion and Coulomb interactions are used to precisely constrain the short-distance behavior of an integrable field theory, which then determines the low energy spectrum. We discuss the relationship of our results to the tunneling measurements of Kang et al. [Nature 403, 59 (2000)].
