Effects of pair freeze-out on photon distributions in BBN epoch
Jeongyoon Choi, Dukjae Jang, Youngshin Kwon +5
We investigate the evolution of non-extensivity in the photon distribution during the Big Bang Nucleosynthesis (BBN) epoch using Tsallis statistics. Assuming a minimal deviation fr…
The Non-thermal Energy Window for Laser-Driven Nuclear Reactions
Eunseok Hwang, Heamin Ko, Myung-Ki Cheoun +1
Laser-driven nuclear reactions proceed in non-equilibrium plasma conditions, producing ion energy distributions that are not Maxwellian. Nevertheless, fusion yields in such experim…
Upper Limit of Fusion Reactivity in Laser-Driven Reaction
Eunseok Hwang, Myung-Ki Cheoun, Dukjae Jang
We explore the averaged fusion reactivity of the reaction in tabletop laser experiments using a plasma expansion model. We investigate the energy distribution of…
Constraining Anisotropic Universe Through Big Bang Nucleosynthesis: A Case Study of The Bianchi Type-I Universe
Jiwon Park, Sourav Mridha, Dukjae Jang +2
The isotropy and homogeneity of our Universe are the cardinal principles of modern cosmology built on the definition of metric through the prescription by Friedmann-Lematr…
Big Bang Nucleosynthesis constraints on the Energy-Momentum Squared Gravity: The model
Dukjae Jang, Mayukh R. Gangopadhyay, Myung-Ki Cheoun +2
Scale-independent energy-momentum squared gravity (EMSG) allows different gravitational couplings for different types of sources and has been proven to have interesting implication…
