Holographic realization of constant roll inflation and dark energy: An unified scenario

In the formalism of generalized holographic dark energy, infrared cut-off LIR is to form, LIR=LIR(Lp,L˙p,L¨p,⋯,Lf,L˙f,L¨f,⋯,a,H,H˙,H¨,⋯), where Lp and Lf are particle horizon future horizon, respectively (moreover, a scale factor H Hubble parameter universe). Based on such formalism, we establish realization constant roll inflation during early universe, corresponding depends its derivatives (up second order). The viability this with respect Planck data in turn puts certain bound at time crossing. Such correspondence extended scenario corrected by ultraviolet one, which may originate due quantum effects. Besides mere inflation, further propose an unified cosmic from (at time) energy era late intermediate radiation dominated followed Kamionkowski like reheating stage. scenario, inflationary quantities (like scalar spectral index tensor-to-scalar ratio) EoS present rate) prove be simultaneously compatible observable constraints for suitable ranges other model parameters. Moreover curvature perturbations super-Hubble (with entire era, ensures stability under consideration.
