I would not say that the case is proven," he says, adding that the observed sound waves could have come from an artifact in the Bose-Einstein condensate
A state of matter that forms below a critical temperature in which all bosons (a type of subatomic particle) that comprise the matter fall into the same quantum state.

The recipe called for a Bose-Einstein condensate
, an exotic state of matter produced by cooling a gas to billionths of a degree above absolute zero.
This new state of matter, called Bose-Einstein Condensate
, allows scientists to study the properties of atoms in a suspended state.
Among the topics are squeezing and entanglement in a Bose-Einstein condensate
, the stability of the proton-to-electron mass ratio tested with molecules using an optical link to a primary clock, room-temperature atomic ensembles for quantum memory and magnetometry, ultra-cold ytterbium atoms in optical lattices, and laser spectroscopy on relativistic ion beams.
Close to absolute zero, some atoms and molecules have been made to form a quantum material called a Bose-Einstein condensate
(BEC) - a state in which the particles are all in their lowest possible energy state and behave as a single entity.
Paper topics include spectral and scattering theory for magnetic Schrodinger operators; magnetic Pauli and Dirac operators; magnetic operators on manifolds; microlocal analysis of magnetic Hamiltonians; random Schrodinger operators and quantum Hall effect; Ginsburg-Landau equation, supraconductivity, magnetic bottles; Bose-Einstein condensate
, Gross-Pitaevski equation; and magnetic Lieb-Thirring inequalities, stability of matter.
Furthermore, because Ginzburg-Landau equation represents superfluid dynamics at low-temperature , the fact that we can derive quantization of celestial systems from this equation seems to support the idea of Bose-Einstein condensate
cosmology [42, 43].
We will create a unique quantum state: a Bose-Einstein condensate
of surface plasmons for which quantum properties become apparent in a many-emitter system.
A Bose-Einstein Condensate
is a peculiar state of matter which occurs when a dilute gas of particles (bosons) are cooled to nearly absolute zero (-273 Celsius, -459 Fahrenheit).
Called a Bose-Einstein condensate
, the exotic material had been predicted in the 1920s by Albert Einstein and Indian physicist Satyendra Nath Bose.
A variable spaced transmission grating made out of a single layer of DNA could serve as a diffraction grating for cold atoms, such as those found in a Bose-Einstein condensate
By manipulating atoms supercooled into the weird quantum state known as a Bose-Einstein condensate
, physicists have begun to create rudimentary analogs of electronic circuits, with the atoms playing the part of the electrons (see Page 5).
For instance, Vahala said he now can study quantum effects of matter at resolutions never before attempted: "With 9,000 cores, we have quite easily achieved Bose-Einstein condensate
grids with a resolution of 2,4003, whereas normally, the most I've seen is 5123.
