    Non-minimal coupling influence on the deviation from de Sitter cosmological expansion by I. V. Fomin, S. V. Chervon

    Published 2018-11-01
    “…Abstract We investigate the models of cosmological inflation in generalized scalar–tensor gravity, which we consider as a source of deviation from de Sitter dynamics in the case of GR. …”

    Bounce from inflation by Debottam Nandi

    Published 2020-10-01
    “…We construct a class of viable bouncing models that are conformally related to cosmological inflation. There are three main difficulties in constructing such a model: (i) A stable (attractor) solution, (ii) A non-singular bounce, and (iii) to bypass the no-go theorem that states that simultaneously maintaining the observational bounds on the tensor-to-scalar ratio and the non-Gaussian scalar spectrum are not possible. …”

    Supersymmetric inflation and large-scale structure by Sarkar, S

    Published 1996
    “…In effective supergravity theories following from the superstring, a modulus field can quite naturally set the neccessary initial conditions for successful cosmological inflation to be driven by a hidden sector scalar field. …”

    Knotty inflation and the dimensionality of spacetime by Arjun Berera, Roman V. Buniy, Thomas W. Kephart, Heinrich Päs, João G. Rosa

    Published 2017-10-01
    “…Abstract We suggest a structure for the vacuum comprised of a network of tightly knotted/linked flux tubes formed in a QCD-like cosmological phase transition and show that such a network can drive cosmological inflation. As the network can be topologically stable only in three space dimensions, this scenario provides a dynamical explanation for the existence of exactly three large spatial dimensions in our Universe.…”

    Higgs mechanism and cosmological constant in $$N=1$$ N = 1 supergravity with inflaton in a vector multiplet by Yermek Aldabergenov, Sergei V. Ketov

    Published 2017-04-01
    “…Abstract The $$N=1$$ N = 1 supergravity models of cosmological inflation with an inflaton belonging to a massive vector multiplet and spontaneous SUSY breaking after inflation are reformulated as the supersymmetric U(1) gauge theories of a massless vector superfield interacting with the Higgs and Polonyi chiral superfields, all coupled to supergravity. …”

    Starobinsky–Bel–Robinson Gravity by Sergei V. Ketov

    Published 2022-06-01
    “…The proposed Starobinsky–Bel–Robinson action has only two free parameters, which makes it suitable for verifiable physical applications in black hole physics, cosmological inflation and Hawking radiation.…”
