We describe a new mechanism of dark matter production. If dark matter particles acquire
mass during a first order phase transition, it is energetically unfavorable for them to enter the …

A bstract We investigate various aspects of capacity of entanglement in certain setups
whose entanglement entropy becomes extensive and obeys a volume law. In particular …

We propose a new paradigm for the thermal production of dark matter in the early Universe,
in which dark-matter particles acquire their mass and freeze out spontaneously from the …

A bstract We consider the (Rényi) mutual information,\({I}^{(n)}\left (A, B\right)={S}
_A^{(n)}+{S} _B^{(n)}-{S} _ {A\cup B}^{(n)}\), of distant compact spatial regions A and B in the …

In this study, we investigate the entropies of photons, ideal gas-like dust (baryonic matter),
and a special kind of dark energy in the context of cosmology. When these components …
