 Dear CCL'ers,
 Recently, I've been asked a question about the difference between the Coulomb
 hole and the Fermi hole. Could someone give me an answer?

 In my opinion, the "fermi hole" comes along only by the pauli
 principle,
 that is, it is there even if there is no electron-electron interaction.
 The "coulomb hole" on the other hand vanishes if the electron
 interaction
 is switched off.
 Yours,
