And the idea was for a system with a finite number of - states. The idea was so let's say, the way we had it before, there was one state with energyzero.
这是对有有限状态数的系统的想法，想法是，那么比方说，我们之前采取的方法，有一个状态对应的能量为零。

So in other words, what it's saying is the configurational energy is zero, because everything is stuck in the ground state.
换句话说，它表示构型能量是零，因为所有分子都冻结在基态。

For a pure scalar potential the zeroenergy bound state does exist, and the fractional charge does exist.
