Going Down the Tube Two pillars of modern physics are quantum mechanics and general relativity. So far, both have remained apart with no quantum mechanical description of gravity available. Van Zoest et al. (p. 1540; see the Perspective by Nussenzveig and Barata) present work with a macroscopic quantum mechanical system—a Bose-Einstein condensate (BEC) of rubidium atoms in which the cloud of atoms is cooled into a collective quantum state—in microgravity. By dropping the BEC down a 146-meter… Expand

Topics from this paper

A Drop of Quantum Matter
TLDR
The evolution of a prototypical quantum object, a Bose-Einstein condensate (BEC), under free-fall conditions is followed and the use of BECs in atom interferometers should allow for more sophisticated tests of general relativity. Expand
Shell potentials for microgravity Bose–Einstein condensates
TLDR
This work proposes to implement a realistic experimental framework for generating shell-geometry BEC using radiofrequency dressing of magnetically trapped samples, and discusses specific experimental configurations, applicable inhomogeneities and other experimental challenges. Expand
Degenerate Quantum Gases in Microgravity
Clouds of ultra-cold atoms and especially Bose–Einstein condensates (BEC) provide a source for coherent matter-waves in numerous earth bound experiments. Analogous to optical interferometry,Expand
STE-QUEST - Test of the Universality of Free Fall Using Cold Atom Interferometry

Hypersonic Bose–Einstein condensates in accelerator rings
TLDR
Bose–Einstein condensates are transported at hypersonic speeds over a distance of 15 cm in a neutral-atom accelerator ring while preserving their internal coherence and will facilitate the study of superfluidity and give rise to tunnelling and a large range of transport regimes of ultracold atoms.

Bose–Einstein condensation on a microelectronic chip
TLDR
It is demonstrated that the formation of a condensate can be greatly simplified using a microscopic magnetic trap on a chip, and the possibility of manipulating laser-like coherent matter waves with such an integrated atom-optical system holds promise for applications in interferometry, holography, microscopy, atom lithography and quantum information processing.

Evidence of Bose-Einstein Condensation in an Atomic Gas with Attractive Interactions.

The theory of quantum reflection is extended to account for the mean-field interactions of a condensate which suppresses quantum reflection at low velocity and the reflected condensates show collective excitations as recently predicted. Expand
Observation of Bose-Einstein Condensation in a Dilute Atomic Vapor
TLDR
A Bose-Einstein condensate was produced in a vapor of rubidium-87 atoms that was confined by magnetic fields and evaporatively cooled and exhibited a nonthermal, anisotropic velocity distribution expected of the minimum-energy quantum state of the magnetic trap in contrast to the isotropic, thermal velocity distribution observed in the broad uncondensed fraction.

Anderson localization of a non-interacting Bose–Einstein condensate
TLDR
This work uses a non-interacting Bose–Einstein condensate to study Anderson localization of waves in disordered media and describes the crossover, finding that the critical disorder strength scales with the tunnelling energy of the atoms in the lattice. Expand
