Pauli exclusion

  1. Jul 7, 2006 #1
    sometimes i think, would the pauli exclusion principle still apply if the fermions span a very large spatial distance?

    for example if i have a very very loooong chain of condensed electrons, wouldn't it be possible that the electrons at both ends occasionaly occupy the same quantum state?

    Position is part of the description of a quantum state. When electrons are sufficiently seperated that their wavefunctions effectively do not overlap, there is no Pauli exclusion for their spin states.

    i see.
