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…

Effective Low-Energy Gravitational Potential for Slow Fermions Coupled to Linearised Massive Gravity

A. N. Ivanov, M. Pitschmann, M. Wellenzohn

We analyse the Dirac equation for slow fermions coupled to linearised massive gravity above the Minkowski background and derive the effective low-energy gravitational potential. Th…

Gravity Resonance Spectroscopy and Einstein-Cartan Gravity

Hartmut Abele, Andrei Ivanov, Tobias Jenke +2

The qBounce experiment offers a new way of looking at gravitation based on quantum interference. An ultracold neutron is reflected in well-defined quantum states in the gravity pot…

Standard Electroweak Interactions in Gravitational Theory with Chameleon Field and Torsion

A. N. Ivanov, M. Wellenzohn

We propose a version of a gravitational theory with the torsion field, induced by the chameleon field. Following Hojman et al. Phys. Rev. D17, 3141 (1976) the results, obtained in…

Neutron Interferometry constrains dark energy chameleon fields

H. Lemmel, Ph. Brax, A. N. Ivanov +7

We present phase shift measurements for neutron matter waves in vacuum and in low pressure Helium using a method originally developed for neutron scattering length measurements in…
