Atom interferometry in an optical cavity.
TL;DR: The advantages of using an optical cavity and applications ranging from inertial sensors to tests of gravity in quantum mechanics are discussed, and interference fringes are demonstrated using the first atom interferometer in a optical cavity.

Abstract: We propose and demonstrate a new scheme for atom interferometry, using light pulses inside an optical cavity as matter wave beam splitters. The cavity provides power enhancement, spatial filtering, and a precise beam geometry, enabling new techniques such as low power beam splitters ( 75% contrast and measure the acceleration due to gravity, g, to 60 μg/sqrt[Hz] resolution in a Mach-Zehnder geometry. We use >10(7) cesium atoms in the compact mode volume (600 μm 1/e(2) waist) of the cavity and show trapping of atoms in higher transverse modes. This work paves the way toward compact, high sensitivity, multiaxis interferometry.

TL;DR: The MIGA experiment as mentioned in this paper is an underground long baseline atom interferometer to study gravity at large scale, which uses a hybrid atom-laser antenna to use several atom inter-ferometers simultaneously interrogated by the resonant mode of an optical cavity.

TL;DR: In this article, a cesium matter-wave interferometer near a spherical mass in an ultra-high vacuum chamber was used to constrain a wide class of dark energy theories, including chameleon and other theories that reproduce the observed cosmic acceleration.

No free lunch theorems for optimization
TL;DR: A framework is developed to explore the connection between effective optimization algorithms and the problems they are solving and a number of "no free lunch" (NFL) theorems are presented which establish that for any algorithm, any elevated performance over one class of problems is offset by performance over another class.

TL;DR: In this article, it was shown that there exist effects of potentials on charged particles, even in the region where all the fields (and therefore the forces on the particles) vanish.

TL;DR: It is argued that a number of models in which the energy density of the scalar field red-shifts in a specific manner are studied could reconcile the low dynamical estimates of the mean mass density with the negligibly small spatial curvature preferred by inflation.

TL;DR: In this paper, a large-scale correlation function measured from a spectroscopic sample of 46,748 luminous red galaxies from the Sloan Digital Sky Survey is presented, which demonstrates the linear growth of structure by gravitational instability between z ≈ 1000 and the present and confirms a firm prediction of the standard cosmological theory.
