**/************ Definitions ************/**

**Math definition 1**: A linear operator X has a number of eigenvalues *x1*, *x2*, …, *xn*, and their corresponding eigenstates, |*x1*>, |*x2*>, …, |*xn*>, which satisfies:

X|*x1*> = *x1*|*x1*>

X|*x2*> = *x2*|*x2*>

…

X|*xn*> = *xn*|*xn*>

Those eigenvalues are complex numbers.
