Quantum gravitational states of ultracold neutrons as a tool for probing of beyond-Riemann gravity
A. N. Ivanov, M. Wellenzohn, H. Abele
We analyze a possibility to probe beyond-Riemann gravity (BRG) contributions, introduced by Kostelecky and Li (see Phys. Rev. D 103, 024059 (2021) and Phys. Rev. D 104, 044054 (202…
Einstein-Cartan Gravity with Torsion Field Serving as Origin for Cosmological Constant or Dark Energy Density
A. N. Ivanov, M. Wellenzohn
We analyse the Einstein-Cartan gravity in its standard form cal-R = R + cal-K^2, where cal-R and R are the Ricci scalar curvatures in the Einstein-Cartan and Einstein gravity, resp…
Can Chameleon Field be identified with Quintessence ?
A. N. Ivanov, M. Wellenzohn
In the Einstein-Cartan gravitational theory with the chameleon field, changing its mass in dependence of a density of its environment, we analyze the Friedmann-Einstein equations f…
Exact Solution for Chameleon Field, Self-Coupled Through the Ratra-Peebles Potential with n = 1 and Confined Between Two Parallel Plates
A. N. Ivanov, G. Cronenberg, R. Höllwieser +4
We calculate the chameleon field profile, confined between two parallel plates, filled with air at pressure and room temperature and separated by the dist…
Spin Precession of Slow Neutrons in Einstein-Cartan Gravity with Torsion, Chameleon and Magnetic Field
A. N. Ivanov, M. Wellenzohn
We analyse a spin precession of slow neutrons in the Einstein-Cartan gravity with torsion, chameleon and magnetic field. For the derivation of the Heisenberg equation of motion of…
Effective Low-Energy Potential for Slow Dirac Fermions in Einstein-Cartan Gravity with Torsion and Chameleon
A. N. Ivanov, M. Wellenzohn
We derive the most general effective low-energy potential to order O(1/m) for slow Dirac fermions with mass m, coupled to gravitational, chameleon and torsion fields in the Einstei…
