摘要
本文提出Massive格点Schwinger模型的一种新的Hamiltonian,找到其准确基态.对Naive和Susskind两种费米子方案,准确计算了无穷长弦弦张力,结果均为1/2e^2,与Massless格点Schwinger模型的结果相同.这表明Massive和Massless格点Schwinger模型同样地给出线性禁闭势,并且当α→0时没有解除禁闭的相变发生,与连续理论现有的结果一致.
In this paper a new form of the Hamiltonian of the massive lattice Schwinger model is proposed and its exact ground state is found.The string tension is calculated exactly and the result is 1/2e^2 for both Naive and Susskind fermions.
