  1. Doch der niederländische Physiker Gerardus "Gerard" 't Hooft, der 1999 für seine Beiträge zur Quantenfeldtheorie gemeinsam mit seinem Lehrer Martinus Veltman den Nobelpreis für ...

  2. 24. Apr. 2024 · Gerardust Hooft (born July 5, 1946, Den Helder, Neth.) is a Dutch physicist, who was a corecipient with Martinus J.G. Veltman of the 1999 Nobel Prize for Physics for their development of a mathematical model that enabled scientists to predict the properties of both the subatomic particles that constitute the universe and the ...

  3. 23. Apr. 2024 · Despite these efforts, soon after Duff’s work, a new result pointed out new theoretical difficulties for quantum GR that slowed the research in this direction. Gerard ’t Hooft and Martinus Veltman proved that gravity loses its one-loop finiteness when coupled with matter .

    9. Mai 2024 · Der Nobelpreisträger Gerardt Hooft (2013) kritisiert wie Vertreter konkurrierender Theorien zur Quantengravitation (wie der Schleifenquantengravitation, Carlo Rovelli, Lee Smolin), dass die Stringtheorie zu sehr konventionellen Auffassungen der Rolle der Raumzeit in der Quantenmechanik verhaftet ist.

  5. 2. Mai 2024 · In their presentations of fundamental interactions, written from the particle physics perspective, Gerard 't Hooft and Martinus Veltman gave good arguments for taking the original, non-regularized Feynman diagrams as the most succinct representation of our present knowledge about the physics of quantum scattering of fundamental ...

  6. 24. Apr. 2024 · We consider the group formed by finite renormalizations as an infinite-dimensional Lie group. It is demonstrated that for the finite renormalization of the gauge coupling constant its generators L ^ n \hat L_n L ^ n with n ≥ 1 n\ge 1 n ≥ 1 satisfy the commutation relations of the Witt algebra and, therefore, form its subalgebra.

  7. 26. Apr. 2024 · Gerardust Hooft and Martinus Veltman had shown that these non-Abelian theories are renormalizable and thus mathematically consistent at all energy scales. This work enabled ’t Hooft to show that Yang–Mills theories can be asymptotically safe, long before the minus sign controversy and the following dilemma of attribution [ 11 ].
