Analytically derived limits on short-range fifth forces from quantum states of neutrons in the Earth's gravitational field
Alexander Westphal, Hartmut Abele, Stefan Baessler
Recently, quantum states of ultra-cold neutrons in the Earth's gravitational field have been observed for the first time. From the fact that they are consistent with Newtonian grav…
A New Constraint for the Coupling of Axion-like particles to Matter via Ultra-Cold Neutron Gravitational Experiments
S. Baessler, V. V. Nesvizhevsky, K. V. Protasov +1
We present a new constraint for the axion monopole-dipole coupling in the range of 1 micrometer to a few millimeters, previously unavailable for experimental study. The constraint…
A quantum mechanical description of the experiment on the observation of gravitationally bound states
Alexander Westphal, H. Abele, S. Baessler +4
Quantum states in the Earth's gravitational field were observed, when ultra-cold neutrons fall under gravity. The experimental results can be described by the quantum mechanical sc…
Measurement of quantum states of neutrons in the Earth's gravitational field
V. V. Nesvizhevsky, H. G. Boerner, A. M. Gagarsky +11
The lowest stationary quantum state of neutrons in the Earth's gravitational field is identified in the measurement of neutron transmission between a horizontal mirror on the botto…
