Kaluza-Klein models: can we construct a viable example?

Maxim Eingorn, Alexander Zhuk

In Kaluza-Klein models, we investigate soliton solutions of Einstein equation. We obtain the formulas for perihelion shift, deflection of light, time delay of radar echoes and PPN…

Classical tests of multidimensional gravity: negative result

Maxim Eingorn, Alexander Zhuk

In Kaluza-Klein model with toroidal extra dimensions, we obtain the metric coefficients in a weak-field approximation for delta-shaped matter sources. These metric coefficients are…

Bouncing inflation in nonlinear $R^{2} + R^{4}$ gravitational model

Tamerlan Saidov, Alexander Zhuk

We study a gravitational model with curvature-squared $R^{2}$ and curvature-quartic $R^{4}$ nonlinearities. The effective scalar degree of freedom $ϕ$ (scalaron) has a multi-valued pot…
