Anisotropic Fractional Cosmology: K-Essence Theory
Fractal and Fractional, 2023 In the particular configuration of the scalar field k-essence in the Wheeler–DeWitt quantum equation, for some age in the Bianchi type I anisotropic cosmological model, a fractional differential equation for the scalar field arises naturally.

Cosmological Relativity: A New Theory of Cosmology
, 2000 A general-relativistic theory of cosmology, the dynamical variables of which are those of Hubble's, namely distances and redshifts, is presented. The theory describes the universe as having a three-phase evolution with a decelerating expansion followed by a constant and an accelerating expansion, and it predicts that the universe is now in the latter ...

Resolving curvature singularities in holomorphic gravity [PDF]
, 2011 We formulate a holomorphic theory of gravity and study how the holomorphy symmetry alters the two most important singular solutions of general relativity: black holes and cosmology. We show that typical observers (freely) falling into a holomorphic black

Universe, 2020 In this work, we study the impact of quantum entanglement on the two-point correlation function and the associated primordial power spectrum of mean square vacuum fluctuation in a bipartite quantum field theoretic system.

Quasidilaton: Theory and cosmology
Physical Review D, 2013 General Relativity (GR), with or without matter fields, admits a natural extension to a scale invariant theory that requires a dilaton. Here we show that the recently formulated massive GR, minimally coupled to matter, possesses a new global symmetry related to scaling of the reference coordinates w.r.t. the physical ones.

Anomaly Cancelation in Field Theory and F-theory on a Circle [PDF]
, 2016 We study the manifestation of local gauge anomalies of four- and six-dimensional field theories in the lower-dimensional Kaluza-Klein theory obtained after circle compactification. We identify a convenient set of transformations acting on the whole tower

Value of the Cosmological Constant in the Cosmological Relativity Theory
International Journal of Theoretical Physics, 2002 It is shown that the cosmological relativity theory prdicts the value Lambda = 1.934 x 10^-35 s^-2 for the cosmological constant. This value of Lambda is in exellent agreement with the measurements recently obtained by the High-Z Supernova Team and the Supernova Cosmology Project.

Exact holography and black hole entropy in N=8 and N=4 string theory [PDF]
, 2017 We compute the exact entropy of one-eighth and one-quarter BPS black holes in N=8 and N=4 string theory respectively. This includes all the N=4 CHL models in both K3 and T^4 compactifications.

Precision probes of QCD at high energies
Journal of High Energy Physics, 2017 New physics, that is too heavy to be produced directly, can leave measurable imprints on the tails of kinematic distributions at the LHC. We use energetic QCD processes to perform novel measurements of the Standard Model (SM) Effective Field Theory.

Journal of High Energy Physics, 2020 To confront the numerical results of Γdiff with the analytical results from section 2.3, we originally considered the theoretical prediction for the diffusion rate given by eq. (2.17), which we re-wrote in eq. (4.25).
