quantum mechanics - Example of a wavefunction that cannot be represented by a single Slater determinant


I know that in general, interacting fermions cannot necessarily be described by a single Slater determinant. Can anyone provide a simple example of a state that has no such representation?



Answer



How about Ψ(x1,x2)(x1x2)e(x1x2)2?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
