The Wilsonian Idea of Renormalizationfected by unphysical ultraviolet divergences. For instance, a systematic study of scattering amplitudes in Quantum Electrodynamics show that, due to the singular high-energy behavior of the theory, Feynman diagrams containing loops result in an infinite contribution to the transition amplitude.作者: Supplement 時間: 2025-3-22 03:28 作者: 樂意 時間: 2025-3-22 06:31
Quantum Gravity on Foliated Spacetimesy requires the spacetime to be Lorentzian, the EAA is defined by means of a Euclidean path integral. In the context of Quantum Field Theory, the Lorentzian signature can be recovered by Wick-rotating all time-like quantities.作者: Musket 時間: 2025-3-22 09:01 作者: 貧窮地活 時間: 2025-3-22 15:32

Inflationary Cosmology from Quantum Gravity-Matter SystemsThe Asymptotic Safety Theory for Quantum Gravity provides a natural framework for the description of gravity within the context of Quantum Field Theory. As the resulting effective action smoothly interpolates between the short and long-distance regimes, the FRG also provides an ideal tool to study phenomenological implications of Quantum Gravity.作者: 書法 時間: 2025-3-26 08:15 作者: 羽毛長成 時間: 2025-3-26 10:25 作者: CANE 時間: 2025-3-26 12:59 作者: 和音 時間: 2025-3-26 19:23 作者: 山羊 時間: 2025-3-26 23:41 作者: dysphagia 時間: 2025-3-27 04:37
