Thoughts Concerning the Origin of Our Fractal Universe: 《Journal of Modern Physics》2025年第1期167-197,共31页J. C. Botke; During the past few decades, it has become clear that the distribution, sizes, and masses of cosmic structures are best described as fractal rather than homogeneous. This means that an entirely different formalism is ...; 关键词：Early Universe Fractal Distributions NUCLEOSYNTHESIS Cosmic Structures Time-Varying Curvature

Nucleosynthesis in the little bang: 《Nuclear Science and Techniques》2024年第8期1-4,共4页Marcus Bleicher; A new approach based on relativistic kinetic equations is proposed to solve the long-standing puzzle of light cluster formation, also called nucleosynthesis, in high-energy heavy-ion collisions. This method addresses ...; 关键词：SYNTHESIS RELATIVISTIC CLUSTER

The Origin of Cosmic Structures Part 6: CMB Anisotropy: 《Journal of High Energy Physics, Gravitation and Cosmology》2024年第1期257-276,共20页J. C. Botke; In a recent series of papers, we introduced a new model of nucleosynthesis in which the matter content of the universe came into existence at a time of about 4 × 10^-5 s. At that time, a small percentage of...; 关键词：CMB ANISOTROPY Dispersion NUCLEOSYNTHESIS Early Universe Time-Varying Curvature

Impact of the new ^(12)C+^(12)C reaction rate on presupernova nucleosynthesis: 《Chinese Physics C》2023年第3期206-217,共12页辛文宇野本憲一赵刚吴文博; Supported by the National Natural Science Foundation of China(11988101,11890694);the National Key R&D Program of China(2019YFA0405502);K.Nomoto is supported by the World Premier International Research Center Initiative(WPI),MEXT,Japan,and the Japan Society for the Promotion of Science(JSPS)KAKENHIgrant(JP17K05382,JP20K04024,JP21H04499)。; The ^(12)C+^(12)C reaction rate plays an essential role in stellar evolution and nucleosynthesis.Nevertheless,the uncertainties of this reaction rate are still large.We calculate a series of stellar evolution models w...; 关键词：reaction rate presupernova NUCLEOSYNTHESIS massive stars
