Holographic complexity and noncommutative gauge theory
Journal of High Energy Physics, 2018 We study the holographic complexity of noncommutative field theories. The four-dimensional N = 4 $$ \mathcal{N}=4 $$ noncommutative super Yang-Mills theory with Moyal algebra along two of the spatial directions has a well known holographic dual as a type

Holographic spacetime, black holes and quantum error correcting codes: a review
European Physical Journal C: Particles and Fields, 2022 This article reviews the progress in our understanding of the reconstruction of the bulk spacetime in the holographic correspondence from the dual field theory including an account of how these developments have led to the reproduction of the Page curve ...

Warm Higgs–Starobinsky inflation
European Physical Journal C: Particles and Fields, 2022 In this work, we investigate the Higgs–Starobinsky (HS) model in the context of warm inflation scenario. The dissipative parameter as a linear form of temperature of warm inflation is considered with strong and weak regimes.

DFT in supermanifold formulation and group manifold as background geometry
Journal of High Energy Physics, 2019 We develop the formulation of DFT on pre-QP-manifold. The consistency conditions like section condition and closure constraint are unified by a weak master equation. The Bianchi identities are also characterized by the pre-Bianchi identity.

Non-minimal coupled warm inflation with quantum-corrected self-interacting inflaton potential
European Physical Journal C: Particles and Fields, 2022 In this work, we investigate the non-minimally coupled scenario in the context of warm inflation with quantum-corrected self-interacting potential. We transform the potential in the Jordan frame to the Einstein frame and consider a dissipation parameter ...

SSRN Electronic Journal, 2023 In cosmological special relativity theory, we study Maxwell equations, electromagnetic wave equations and functions. In the cosmological special theory of relativity, we study energy?momentum relations, the Klein-Gordon equation and wave functions. If we solve the Klein?Gordon equation, we obtain the Yukawa potential in the cosmological inertial frame.

Axions: Theory and Cosmological Role [PDF]
Annual Review of Nuclear and Particle Science, 2013 We review recent developments in axion cosmology. Topics include axion cold dark matter, axions from topological defects, axion isocurvature perturbation and its non-Gaussianity, and axino/saxion cosmology in a supersymmetric axion model.

Unimodular Approaches to the Cosmological Constant Problem
Universe, 2023 We review selected aspects of unimodular gravity and we discuss its viability as a solution of the old cosmological constant problem. In unimodular gravity, the cosmological constant is promoted to a global degree of freedom.

Theory of cosmological perturbations with cuscuton [PDF]
Journal of Cosmology and Astroparticle Physics, 2017 This paper presents the first derivation of the quadratic action for curvature perturbations, $ζ$, within the framework of cuscuton gravity. We study the scalar cosmological perturbations sourced by a canonical single scalar field in the presence of cuscuton field.

Lorentz invariant field theory on κ-Minkowski space [PDF]
, 2010 It is by now well established that the momentum space associated with the non-commutative κ-Minkowski space is a submanifold of de Sitter space. It has been noted recently that field theories built on such momentum space suffer from a subtle form of ...
