Pauli reacts in a very positive way on Heisenberg's letter of the 6 November 1933 and hopes he will continue his calculations.
Pauli, WolfgangPauli proves that Heisenberg's theory given in his letter of the 6 November 1933 is identical with a former theory developed by Pauli and Heisenberg.
Pauli, WolfgangPauli agrees with Heisenberg's pessimism regarding infinite energies, but he thinks one should try to separate the problem of self-energy from that of the hole theory.
Pauli, WolfgangPauli does not believe that the theory of holes can be improved without essentially new ideas.
Pauli, WolfgangPauli writes of Weisskopf's and his own result that the material energy of photons becomes infinite in their theory. He remarks about "substraction physics": the fact that polarizability of the vacuum and self-energy of material particles are both becoming infinite must have a common root. The real progress of the theories will be found in the amalgamation of electromagnetic field and matter field.
Pauli, WolfgangAddition to the last letter of the 24 October 1934 (heisenberg_0205).
Pauli, WolfgangPauli is interested in Heisenberg's new calculations on the hole theory and on the problem of magnetic nuclear moments.
Pauli, WolfgangPauli believes that the introduction of singulary density matrices is not the physically correct way to a solution.
Pauli, WolfgangPauli writes on some afterthoughts about Heisenberg's letter.
Pauli, WolfgangPauli writes that his view that Delta-type interaction between more than two neutrinos must lead to infinities was influenced by a paper by Thomas (Phys. Rev. 47,903). This does not affect Pauli's and Heisenberg's case.
