Scalar Field Cosmology from a Modified Poisson Algebra

Leon, Genly; Millano, Alfredo D.; Paliathanasis, Andronikos


We investigate the phase space of a scalar field theory obtained by minisuperspace deformation. We consider quintessence or phantom scalar fields in the action that arises from minisuperspace deformation on the Einstein-Hilbert action. We use a modified Poisson algebra where Poisson brackets are the alpha-deformed ones and are related to the Moyal-Weyl star product. We discuss early- and late-time attractors and reconstruct the cosmological evolution. We show that the model can have the lambda CDM model as a future attractor if we initially consider a massless scalar field without a cosmological constant term.
