Spinor Bose-Einstein condensates (BECs) are highly controllable ultracold atom systems whose internal (spin) degree of freedom allows for different types of magnetic ordering, therefore offering a wider span of magnetic quantum phases.
Molecules were made in ultracold atom clouds called Bose-Einstein condensates (BEC)--a possible step toward molecular BECs (157: 104).
For us, this new, weakly bound state of matter is an exciting new possibility of investigating the physics of ultracold atoms," says Joachim BurgdE[micro]rfer.
A weak laser beam was shone through a dense cloud of the ultracold atoms, and what emerged from the other side were photons bound in pairs or triplets - a completely new form of photonic matter.
In this field, Ultracold atoms promise novel approaches with a specific degree of control.

Ultracold atoms should lead to increasingly sensitive interferometers, devices that can measure gravity and test the limits of quantum theory.
They cover experimental methods of ultracold atomic physics, theory and experiment with Bose gas, experiment and theory with the Fermi gases and superfluids, low-dimensional atomic Bose gases, ultracold atoms and molecules in optical lattices, unitary Fermi gases, and potential insights into non-equilibrium behavior from atomic physics.
One candidate for such a computer is a so-called optical lattice, in which ultracold atoms are coaxed by strategically placed laser beams into a grid arrangement, rather like eggs in an egg carton.
