[來源] 課本習題
[題目] Consider a infinite square well with walls at x = -1 and x = 1.
If a delta function potential 3δ (x) also appears within the well,
find the ground state energy and wave function for a particle of
mass m = 1.
[瓶頸]
delta function 的 potential 在無限井之中,
我是要把它當成邊界,算兩邊的波方程,還是?
不知道該如何下手中
感謝

1F:→ hellwize:假設原點有個方型potential 底為t 高為3/t 算完後再t->0 11/09 17:23
2F:→ harveyhs:解兩邊的自由波方程然後在原點處理邊界條件問題就足夠了 11/09 17:25
3F:→ jj1002:所以是兩邊的波與ground state各自算出來? 11/09 20:09
