WebFermi heap and Fermi hole refer to two closely related quantum phenomena that occur in many-electron atoms. They arise due to the Pauli exclusion principle, according to which no two electrons can be in the same quantum state in a system (which, accounting for electrons' spin, means that there can be up to two electrons in the same orbital).Due to … WebMar 17, 2024 · The annihilation of electron-positron pairs into pairs of photons that Mercedes has introduced int the previous video is not the only annihilation reaction. There's a whole class of reactions of electron-positron annihilation into fermion-antifermion pairs and the example is shown here. We do not include the reaction e+ e- -> e+ e-, which is ...
