Non-minimal coupling for the gravitational and electromagnetic fields: black hole solutions and solitons

Alexander B. Balakin, Vladimir V. Bochkarev, José P. S. Lemos

Using a Lagrangian formalism, a three-parameter non-minimal Einstein-Maxwell theory is established. The three parameters, , and , characterize the cross-terms in th…

The Afterglows of Swift-era Gamma-Ray Bursts. I. Comparing pre-Swift and Swift era Long/Soft (Type II) GRB Optical Afterglows

D. A. Kann, S. Klose, B. Zhang +73

We have gathered optical photometry data from the literature on a large sample of Swift-era gamma-ray burst (GRB) afterglows including GRBs up to September 2009, for a total of 76…

Nonminimal isotropic cosmological model with Yang-Mills and Higgs fields

A. B. Balakin, H. Dehnen, A. E. Zayats

We establish a nonminimal Einstein-Yang-Mills-Higgs model, which contains six coupling parameters. First three parameters relate to the nonminimal coupling of non-Abelian gauge fie…

Slowly rotating wormholes: the first order approximation

P. E. Kashargin, S. V. Sushkov

We discuss a solution describing a rotating wormhole in the theory of gravity with a scalar field with negative kinetic energy. To solve the problem we use the assumption about slo…

Ray optics in the field of non-minimal Dirac monopole

Alexander B. Balakin, Alexei E. Zayats

Based on the analogy with non-minimal SU(2) symmetric Wu-Yang monopole with regular metric, the solution describing a non-minimal U(1) symmetric Dirac monopole is obtained. In orde…

Non-minimal Einstein-Yang-Mills-Higgs theory: Associated, color and color-acoustic metrics for the Wu-Yang monopole model

A. B. Balakin, H. Dehnen, A. E. Zayats

We discuss a non-minimal Einstein-Yang-Mills-Higgs model with uniaxial anisotropy in the group space associated with the Higgs field. We apply this theory to the problem of propaga…

Self-force of a point charge in the space-time of a symmetric wormhole

Nail R. Khusnutdinov, Ilya V. Bakhmatov

We consider the self-energy and the self-force for an electrically charged particle at rest in the wormhole space-time. We develop general approach and apply it to two specific pro…
