Abstract Weakly-and Feebly-Interacting Massive Particles (WIMPs and FIMPs) are among
the best-motivated dark matter (DM) candidates. In this paper, we investigate the production …

We discuss the present state and planned updates of CosmoLattice, a cutting-edge code for
lattice simulations of non-linear dynamics of scalar-gauge field theories in an expanding …

The inflationary reheating phase begins when accelerated expansion ends. As all Standard
Model particles are coupled to gravity, gravitational interactions will lead to particle …

We study the effects on particle production of a Planck-suppressed coupling between the
inflaton and a scalar dark matter candidate, χ. In the absence of this coupling the dominant …

The main limitation for preinflationary breaking of Peccei-Quinn (PQ) symmetry is the upper
bound on the Hubble rate during inflation from axion isocurvature fluctuations. This leads to …

The physical and mathematical properties of nonequatorial (m≠ l) scalar clouds that are
supported by extremal Kerr black holes are studied analytically in the dimensionless large …

We investigate the generation of the baryon asymmetry within the framework of
cosmological gravitational particle production, employing the Bogoliubov approach. We …

We explore various aspects concerning the role of vector bosons during the reheating
process. Generally, reheating occurs during the period of oscillations of the inflaton …

It has recently been revealed [R. Gervalle and MS Volkov, Phys. Rev. Lett. 133, 171402
(2024) PRLTAO 0031-9007 10.1103/PhysRevLett. 133.171402] that magnetically charged …

We consider gravitational particle production (GPP) of dark matter (DM) under supergravity
framework, where $\alpha $-attractor inflation model is used. The particle spectrum is …
