  • Bulk viscous quintessential inflation 

    Haro Cases, Jaume; Pan, Supriya (2018-04-01)
    Article
    Open Access
    In a spatially-flat Friedmann–Lemaître–Robertson–Walker universe, the incorporation of bulk viscous process in general relativity leads to an appearance of a nonsingular background of the universe that both at early and ...
  • Evolution and dynamics of a matter creation model 

    Pan, Supriya; Haro Cases, Jaume; Paliathanasis, A.; Slagter, R.J. (2016-05-01)
    Article
    Open Access
    In a flat Friedmann–Lemaître–Robertson–Walker (FLRW) geometry, we consider the expansion of the universe powered by the gravitationally induced ‘adiabatic’ matter creation. To demonstrate how matter creation works well ...
  • Note on bouncing backgrounds 

    Haro Cases, Jaume; Pan, Supriya (American Physical Society (APS), 2018-05-15)
    Article
    Open Access
    The theory of inflation is one of the fundamental and revolutionary developments of modern cosmology that became able to explain many issues of the early Universe in the context of the standard cosmological model (SCM). ...
  • Reheating in quintessential inflation via gravitational production of heavy massive particles: a detailed analysis 

    Haro Cases, Jaume; Yang, Weiqiang; Pan, Supriya (2019-01-01)
    Article
    Open Access
    An improved version of the well-known Peebles-Vilenkin model unifying early inflationary era to current cosmic acceleration, is introduced in order to match with the theoretical values of the spectral quantities provided ...
  • Simple inflationary quintessential model 

    Haro Cases, Jaume; Amorós Torrent, Jaume; Pan, Supriya (2016-04-12)
    Article
    Open Access
    In the framework of a flat Friedmann-Lemaitre-Robertson-Walker geometry, we present a nongeodesically past complete model of our Universe without the big bang singularity at finite cosmic time, describing its evolution ...
  • Simple inflationary quintessential model. II. Power law potentials 

    Haro Cases, Jaume; Amorós Torrent, Jaume; Pan, Supriya (American Physical Society, 2016-09-21)
    Article
    Open Access
    The present work is a sequel of our previous work [Phys. Rev. D 93, 084018 (2016)] which depicted a simple version of an inflationary quintessential model whose inflationary stage was described by a Higgs-type potential ...
  • The Peebles–Vilenkin quintessential inflation model revisited 

    Haro Cases, Jaume; Amorós Torrent, Jaume; Pan, Supriya (springer-Verlag, 2019-06-01)
    Article
    Open Access
    We review the well-known Peebles–Vilenkin (PV) quintessential inflation model and discuss its possible improvements in agreement with the recent observations. The improved PV model depends only on two parameters: the ...
