Spectroscopy of charmonium-like mesons, heavy-light mesons with charm, AdS/QCD, and configurational entropy Open
Heavy-light-flavor meson resonances with charm, in the $D^0$ and $D^*$ families, and charmonium-like states, in the $η_c$ and $χ_{c1}$ families, are explored and discussed in the AdS/QCD model with four quark flavors. The differential conf…

Chaotic behaviour of the Earth System in the Anthropocene Open
It is shown that the Earth System (ES) can, due to the impact of human activities, behave in a chaotic fashion. Our arguments are based on the assumption that the ES can be described by a Landau–Ginzburg model, which on its own allows for …
