Exact Results in Quantum Theory & GravityŚcisłe rezultaty teorii kwantów i grawitacji2021/2022prof. dr hab. Jan Dereziński, prof. dr hab. Krzysztof Meissner dr Wojciech Kamiński, dr Grzegorz Łach <--Pasteura 5, room 1.40, Fridays 14:15 - < 16:00--> |
Abstract:
In this talk, we study the relationship between Dirac-Fock energyand electron-positron Hartree–Fock energy. We prove the longstanding conjecture due to Mittleman: the Dirac–Fock model is an approximation of QED when the fine structure constant α is small and the velocity of light c is large. We also prove some properties about Dirac-Fock model. In addition, we will talk about some perspectives on the Dirac many-body problem.
