| 41. | When there are external lines, the amplitudes are antisymmetric when two Fermi insertions for identical particles are interchanged.
|
| 42. | In other words, in an antisymmetric state two identical particles cannot occupy the same single-particle states.
|
| 43. | A possible alternative to the antisymmetric explanation could be based on the difficulty of parsing languages with rightward movement.
|
| 44. | These results imply that Universal Grammar is equipped with the binary head-directionality, and is not antisymmetric.
|
| 45. | This is not satisfactory for fermions, such as electrons, because the resulting wave function is not antisymmetric.
|
| 46. | We can construct symmetric and antisymmetric multi-particle states out of continuous eigenstates in the same way as before.
|
| 47. | For the former case, the trivial representation could either lie in the symmetric product, or the antisymmetric product.
|
| 48. | Within the Hartree Fock method of quantum chemistry, the antisymmetric wave function is approximated by a single Slater determinant.
|
| 49. | By comparison with the solutions above, we can see that only the antisymmetric ones have nodes at the origin.
|
| 50. | What this means is that the wave equation must also be antisymmetric with respect to the exchange of two electrons.
