A Gravity of Earth Measurement with a qBOUNCE Experiment

  author={Gunther Cronenberg and Hanno Filter and Martin Thalhammer and Tobias Jenke and Hartmut Abele and Peter Geltenbort},
  journal={arXiv: High Energy Physics - Experiment},
We report a measurement of the local acceleration $g$ with ultracold neutrons based on quantum states in the gravity potential of the Earth. The new method uses resonant transitions between the states $|1> -> |3>$ and for the first time between $|1> -> |4>$. The measurements demonstrate that Newton's Inverse Square Law of Gravity is understood at micron distances at an energy level of $10^{-14}$ eV with $\frac{\Delta g}{g}=4\times10^{-3}$. The results provide constraints on any possible gravity…

Tests of fundamental quantum mechanics and dark interactions with low-energy neutrons

Among the known particles, the neutron takes a special position, as it provides experimental access to all four fundamental forces and a wide range of hypothetical interactions. Despite being

Bounding quantum dark forces

Dark sectors lying beyond the Standard Model and containing sub-GeV particles which are bilinearly coupled to nucleons would induce quantum forces of the Casimir-Polder type in ordinary matter. Such

P o S ( I N P C 2 0 1 6 ) 3 5 9 Cold and Ultracold Neutrons as Probes of New Physics

Despite the great success of the Standard Model, many key questions in particle physics, astrophysics, and cosmology are unanswered. In particular, more than 95 % of the universe consists of unknown

Tests of chameleon gravity

The present state-of-the-art searches for screened scalars coupled to matter are summarized, and the current bounds on f(R) models that exhibit the chameleon mechanism are translated into a single parametrization to survey the state of the models.

Efficient Quantum Measurement Engines.

It is found that unit efficiency can be approached when one measurement outcome prepares the initial state of the next engine cycle, while the other outcomes leave the original state nearly unchanged.

EuCAPT White Paper: Opportunities and Challenges for Theoretical Astroparticle Physics in the Next Decade

Astroparticle physics is undergoing a profound transformation, due to a series of extraordinary new results, such as the discovery of high-energy cosmic neutrinos with IceCube, the direct detection

Theoretical and Phenomenological Viability of Scalar Field Theories

The objective of this Thesis is to explore several related questions with regards to criteria for viability in scalar field theories. Roughly the first half is devoted to theoretical criteria, while

Dynamics of a composite quantum bouncing ball.

I construct the state of a quantum particle with internal degree of freedom bouncing on a perfect reflector in presence of gravity. I predict from the result that revival of position expectation is



Gravity resonance spectroscopy constrains dark energy and dark matter scenarios.

These measurements demonstrate that Newton's inverse square law of gravity is understood at micron distances on an energy scale of 10-14  eV, and is able to provide constraints on any possible gravitylike interaction.

Probing the neutron’s electric neutrality with Ramsey spectroscopy of gravitational quantum states of ultracold neutrons

We propose to test the electric neutrality of neutrons by a new technique using the spectroscopy of quantum states of ultra-cold neutrons in the gravity potential above a vertical mirror. The new

Strongly coupled chameleons and the neutronic quantum bouncer.

It is shown that the presence of a chameleon field over a planar plate would alter the energy levels of ultracold neutrons in the terrestrial gravitational field.

Ramsey's method of separated oscillating fields and its application to gravitationally induced quantum phase shifts

We propose to apply Ramsey's method of separated oscillating fields to the spectroscopy of the quantum states in the gravity potential above a horizontal mirror. This method allows a precise

Atom-interferometry constraints on dark energy

The results of experiments that controlled for dark energy screening mechanisms in individual atoms, not bulk matter constrained a wide class of dark energy theories, including a range of chameleon fields and other theories that reproduce the observed cosmic acceleration.

Inertial and gravitational mass in quantum mechanics

We show that in complete agreement with classical mechanics, the dynamics of any quantum mechanical wave packet in a linear gravitational potential involves the gravitational and the inertial mass
