Helicity-supported stationary spacetimes: A class of finite-energy, horizonless, axisymmetric solutions
Francisco S. N. Lobo, Tiberiu Harko
We construct a class of stationary, axisymmetric, horizonless spacetimes whose curvature is generated entirely by smooth, localised differential rotation , while the spatial…
Analytic semiclassical backreaction of a Schwarzschild black hole in a finite cavity: horizon shift, temperature renormalization, and canonical stability in the Hartle-Hawking State
G. G. L. Nashed, Alnadhief H. A. Alfedeel, Tiberiu Harko
We construct an analytic model of static semiclassical backreaction for a Schwarzschild black hole in the Hartle--Hawking state enclosed within a finite spherical cavity. Using a m…
Dark energy and accelerating cosmological evolution in a Universe with a Weylian boundary
Tiberiu Harko, Shahab Shahidi
We investigate the influence of boundary terms in gravitational field theories, by considering that in the Einstein-Hilbert action the boundary can be described by a non-metric Wey…
Is Dark Energy Dynamical in the DESI Era? A Critical Review
Salvatore Capozziello, Himanshu Chaudhary, Tiberiu Harko +1
We investigate whether the recent DESI DR2 measurements provide or not evidences for dynamical dark energy by exploring the CDM model and its extensions with free $\sum m_ν…
Schrödinger-type gravity-nonmetricity driven cosmological evolution from inflation to the late Universe
Lei Ming, Himanshu Chaudhary, Shi-Dong Liang +2
We consider an gravity theory with a Schrödinger type vectorial non-metricity. In the presence of such a non-metricity, the length of vectors is preserved under autoparal…
Observational tests of the conformal osculating Barthel-Kropina cosmological model
Himanshu Chaudhary, Rattanasak Hama, Tiberiu Harko +2
We consider detailed cosmological tests of dark energy models obtained from the general conformal transformation of the Kropina metric, representing an -type Finslerian geom…
