Cosmology with the Laser Interferometer Space Antenna
Living Reviews in Relativity, 2023 The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravitational-wave backgrounds and their implications for early universe and ...

Dark matter from Affleck-Dine baryogenesis [PDF]
, 1999 Fragmentation of the Affleck-Dine condensate into Q-balls could fill the Universe with dark matter either in the form of stable baryonic balls, or LSP produced from the decay of unstable Q-balls.

Journal of High Energy Physics, 2022 Hawking evaporation of primordial black holes (PBHs) can facilitate the generation of matter-antimatter asymmetry. We focus on ultra-low mass PBHs that briefly dominate the universe and evaporate before the big bang nucleosynthesis.

Journal of High Energy Physics, 2022 Combining the Higgs searches at the LHC, we study the Higgs inflation in the type-I and type-II two-Higgs-doublet models with non-minimally couplings to gravity.

Axion inflation in the strong-backreaction regime: decay of the Anber-Sorbo solution
Journal of High Energy Physics, 2023 Axion inflation coupled to Abelian gauge fields via a Chern-Simons-like term of the form ϕF F ~ $$ \phi F\overset{\sim }{F} $$ represents an attractive inflationary model with a rich phenomenology, including the production of magnetic fields, black holes,

New and Improved Superstring Phenomenology [PDF]
, 1999 Recent developments in string theory have important implications for cosmology. Topics discussed here are inflation, the cosmological constant, smoothing of cosmological singularities, and dark matter from parallel universes.

Cosmological magnetic fields by parametric resonance? [PDF]
, 2000 We investigate the possibility that electromagnetic fluctuations are amplified in expanding universe by parametric resonance, during the oscillatory regime of a scalar field to which they are coupled.

Early Universe models from Noncommutative Geometry [PDF]
, 2009 We investigate cosmological predictions on the early universe based on the noncommutative geometry models of gravity coupled to matter. Using the renormalization group analysis for the Standard Model with right handed neutrinos and Majorana mass terms ...

LHC and ILC Data and the Early Universe Properties [PDF]
, 2009 With the start-up of the LHC, we can hope to find evidences for new physics beyond the Standard Model, and particle candidates for dark matter. Determining the parameters of the full underlying theory will be a long process requiring the combination of ...
