Dirac stars in modified gravity

Zhuldyz Alibekova, Vladimir Dzhunushaliev, Vladimir Folomeev +1

We study Dirac mini-stars in modified gravity, where gravity is sourced by both linear and nonlinear spinor fields. Two-dimensional (2D) and three-dimensional (3D) profiles o…

Non-Abelian monopoles in Einstein-scalar-Gauss-Bonnet gravity

Vladimir Dzhunushaliev, Vladimir Folomeev

We study static, spherically symmetric self-gravitating non-Abelian 't Hooft-Polyakov monopoles in Einstein-scalar-Gauss-Bonnet gravity for two classes of scalar-Gauss-Bonnet coupl…

Fermion condensate at the event horizon

Vladimir Dzhunushaliev, Vladimir Folomeev

Some arguments are considered in favor of the idea that the canonical anticommutation relations for fermions should be modified in curved spacetime near the event horizon of a blac…

Quantum torsion with non-zero standard deviation: non-perturbative approach for cosmology

V. Dzhunushaliev, V. Folomeev, B. Kleihaus +1

Cosmology with non-perturbative quantum corrections resulting from torsion is considered. It is shown that the evolution of closed, open and flat Universes is changed because of th…

Asymptotically flat gravitating spinor field solutions. Step 2 - the compatibility of Dirac equations in a curve and a flat spaces

V. Dzhunushaliev

Using the fact that a spin connection is defined to an accuracy of a vector it is shown that the spin connection should be modified in such a manner that Dirac equation in a curve…

Topology change in quantum gravity and Ricci flows

V. Dzhunushaliev, N. Serikbayev, R. Myrzakulov

The topology change in quantum gravity is modeled by a Ricci flow. In this approach we offer to consider the Ricci flow as a statistical system. The metric in the Ricci flow enumer…

Long-term bounce of the Universe filled with the Higgs field

V. Dzhunushaliev, K. Myrzakulov, R. Myrzakulov

The cosmological solution with a long-term bouncing off time is presented. The solution has a preceding contracting and a subsequent expanding phases and between them there exists…

Strings and Branes under Microscope

V. Dzhunushaliev

It is shown that in the standard vacuum 5D Kaluza-Klein gravity there is wormhole-like solutions which look like strings attached to two D-branes. The asymptotical behaviour of the…

Strings in the Einstein's paradigm of matter

V. Dzhunushaliev

Spherically symmetric solutions with a flux of electric and magnetic fields in Kaluza-Klein gravity are considered. It is shown that under the condition (electric charge ) $\app…

An effective model of the spacetime foam

V. Dzhunushaliev

An approximate model of the spacetime foam is offered in which each quantum handle (wormhole) is a 5D wormhole-like solution. A spinor field is introduced for an effective descript…

An Approximate Model of the Spacetime Foam

V. Dzhunushaliev

An approximate model of the spacetime foam is offered in which a quantum handle (wormhole) is a 5D wormhole-like solution. Neglecting the linear sizes of the wormhole throat we can…

Non-differentiable Degrees of Freedom : Fluctuating Metric Signature

V. Dzhunushaliev, D. Singleton

In this article we investigate the metric signature as a non-differentiable ({\it i.e.} discrete as opposed to continuous) degree of freedom. The specific model is a vacuum 7D Univ…

Nondifferentiable Dynamic: Two Examples

V. Dzhunushaliev

Some nondifferentiable quantities (for example, the metric signature) can be the independent physical degrees of freedom. It is supposed that in quantum gravity these degrees of fr…

Gravitational Flux Tubes

V. Dzhunushaliev, U. Kasper, D. Singleton

By studying multidimensional Kaluza-Klein theories, or gravity plus U(1) or SU(2) gauge fields it is shown that these theories possess similar flux tube solutions. The gauge field…

Flux Tubes in Weyl Gravity

V. Dzhunushaliev, H. -J. Schmidt

The spherically symmetric solutions in Weyl gravity interacting with U(1) or SU(2) gauge fields are examined. It is shown that these solutions are conformally equivalent to an infi…

Experimental test for extra dimensions in Kaluza-Klein gravity

V. Dzhunushaliev, D. Singleton

5D Kaluza-Klein gravity has several nonasymptotically flat solutions which generally, possessed both electric and magnetic charges. In this paper we suggest that these solutions ca…
