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…
Spherically Symmetric solutions in Multidimensional Gravity with the SU(2) Gauge Group as the Extra Dimensions
V. Dzhunushaliev, H. -J. Schmidt, O. Rurenko
The multidimensional gravity on the principal bundle with the SU(2) gauge group is considered. The numerical investigation of the spherically symmetric metrics with the center of s…
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…
Matching Condition on the Event Horizon and the Holography Principle
V. Dzhunushaliev
It is shown that the event horizon of 4D black hole or surfaces of multidimensional wormhole-like solutions reduce the amount of information necessary for determining th…
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…
Domain with Noncompactified Extra Dimensions in Multidimensional Universe with Compactified Extra Dimensions
V. D. Dzhunushaliev
It is supposed that in our Universe with compactified extra dimensions (ED) the domains exist with noncompactified ED. Such domain can be a wormhole-like solution in multidimension…
