We examine the inflationary parameters, such as slow-roll parameters, the scalar power spectrum, tensor power spectrum, spectral index and the tensor to scalar ratio in the presence of scalar field and Chaplygin gas models. We also discuss the recently proposed swampland conjectures. We consider that the inflationary expansion is driven by a standard scalar field with a decay ratio $Gamma$ that has a generic power law dependence on the scalar field $phi$ and the temperature of the thermal bath $T$ is given by $Gamma(phi,T)= C_{phi} frac{T^{a}}{phi^{a-1}}$, where $C_{phi}$ is a dimensionless parameter and $a$ is the inflation decay rate. Assuming that our model bends in a strong dissipative regime $(Rgg1)$, we study the background and perturbative dynamics and obtain the most relevant inflationary observables, such as the scalar power spectrum $mathcal{P_{R}}$, scalar spectral index $n_{s}$, dissipative ratio $R$, the tensor-to-scalar ratio $r$, running of the scalar spectral index $frac{dn_{s}}{dln{k}}$ and the generalized ratio of the Swampland de-Sitter conjecture $frac{acute{T}V}{acute{V}T}$ for three different potentials.","PeriodicalId":10250,"journal":{"name":"Chinese Physics C","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140970084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our investigation commences by computing the Hawking temperature, thereby identifying critical values such as the black hole's critical radius and maximum temperature, essential in delineating its phase transition. Further exploration centers on the analysis of quasi-normal modes in charged AdS black holes immersed in perfect fluid dark matter (PFDM) within the massless scalar field paradigm. Employing the Wentzel-Kramers-Brillouin (WKB) method, we accurately derive the frequencies of these black hole quasi-normal modes (QNMs). Additionally, we conduct a meticulous assessment of how the intensity of the PFDM parameter $alpha$ influences the partial absorption cross sections of the black hole, along with a detailed study of the energy emission rate's frequency variation. The pivotal role of geodesics in understanding astrophysical black hole characteristics is highlighted. Specifically, our investigation examines the influence of the dark matter parameter on photon evolution by computing the black hole's shadow radius. Our findings distinctly demonstrate the significant impact of the PFDM parameter $alpha$ on the boundaries of the black hole's shadow, unveiling crucial insights into its features and interactions. This comprehensive analysis provides profound insights into the intricate dynamics between a charged AdS black hole, novel dark matter, and various physical phenomena, illuminating their interplay and contributing valuable knowledge to the understanding of these cosmic entities.","PeriodicalId":10250,"journal":{"name":"Chinese Physics C","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140980676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Certain fission products, such as 95Zr, 99Mo, 140Ba, 144Ce and 147Nd, serve as burnup monitors, assessing the number of fissions induced by neutrons on 235U. However, current experimental data for these fission products worldwide are inconsistent, introducing significant uncertainty into related scientific research. This study employs the Potential-driving Model to calculate the independent yields of 235U and evaluates its advantages in such calculations. Additionally, we investigate the energy dependence of independent yields for select important products. Furthermore, we calculate the cumulative yields of 95Zr, 99Mo, 140Ba, 144Ce, and 147Nd, and compare them with existing literature data to explore the energy dependence of fission products for 235U. Given the lack of fission product yield data above 14.8 MeV, we extend our calculated incident neutron energy to 20 MeV, aiming to support future scientific research. The Geant4 physical model does not consider the influence of incident neutron energy on the average total kinetic energy of fission fragments; thus, we introduce the excitation function of the total kinetic energy of fission fragments recommended by Madland et al., which effectively describes the experimental data of the average total kinetic energy of fragments formed in 235U fission. This study offers a detailed discussion on the energy dependence of fission product yield and average total kinetic energy.","PeriodicalId":10250,"journal":{"name":"Chinese Physics C","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140999200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Systematic calculations of the low-lying spectra are performed.
