Antisymmetry refers to a property of wave functions that describes how the state of a system changes when two identical particles are exchanged. In an antisymmetric wave function, swapping two particles results in the wave function acquiring a negative sign, indicating that the overall probability for finding these particles in the same state is zero. This property is crucial for understanding the behavior of fermions, which obey the Pauli exclusion principle and highlights the importance of indistinguishable particles in quantum mechanics.
congrats on reading the definition of antisymmetry. now let's actually learn it.
