Bosons have integer spin, fermions have half-integer spin!
玻色子自旋为整数 费米子自旋为半整数
In analogy with the half-integer formula,
结合里德伯公式可以得到
Now suppose the size of the compact dimension is L; then the possible eigenvalues under gradient along this dimension are integer or half-integer multiples of 1/L (depending on the precise boundary conditions).
现在假设紧凑的维度的尺度是L;那么沿这个维度的梯度的可能的特征值是1/L的整数或半整数倍(取决于精确的边界条件)。
His devices consist of rapidly spinning disks of brass, a material made up largely of elements with a total half-integer nuclear spin.
