labs When Eric Cornell started as a postdoc with Carl Wieman at JILA an institute run jointly by the National Institute of Standards and Technology and the University of Colorado in Boulder in 1990 he did his best to transform their second-floor lab into a basement "We had these beautiful windows that looked out over the mountains" Cornell says "and we bought 3-inch-thick Styrofoam and cut it into squares and taped it over them" The quiet and darkness made it easier to fiddle with the homemade lasers they were using to coax atoms into a new state of matter Special issue: Ultracold matter Cornell and Wieman were trying to cool a puff of rubidium gas to within a few billionths of a degree of absolute zero—colder than any place in nature even the 273 kelvins of space They hoped to produce a long-predicted state of matter called a Bose-Einstein condensate (BEC) in which the atoms shed their individual identities and crowd en masse into a single quantum wave In 1995 they succeeded—a triumph that earned them a share of the 2001 Nobel Prize in Physics "We finally unplugged that experiment just 2 years ago" Cornell says Now Cornell and other physicists are taking their atomic wisps out of seclusion and into space Early next year NASA will launch its $70 million Cold Atom Laboratory (CAL) to the International Space Station (ISS) Once in orbit the fully automated rig will create BECs and do other cold atom experiments taking advantage of weightlessness to attain record-low temperatures and break ground for ambitious studies of quantum mechanics and gravity Miniaturization is the key: Experiments that once required a room full of lasers optical elements and vacuum systems can now fit in a device the size of an ice chest with the atoms trapped on the surface of a microchip The effort will stretch the culture of atomic physicists forcing them to share a single remote facility like users of a space telescope "I’ve certainly been pitching this for 20 years really from the beginning of BECs when doing something like this in space seemed crazy" says Robert Thompson a physicist at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena California and CAL’s project scientist Birth of the cool It has been nearly a century since Bose-Einstein condensates (BECs) were first predicted and more than 20 years since they were first made Now scientists are taking the clouds of ultracold atoms into space V Altounian/Science There is one main reason to do atomic physics in space "It’s all about getting away from gravity" says Charles Sackett a physicist at the University of Virginia in Charlottesville and a CAL experimenter Here’s the problem: To make a BEC physicists use magnets and lasers to trap and chill atoms so that their speeds drop from thousands of meters per second to centimeters per second—slower than a walk But to probe a BEC they must release it from its trap and shine laser light on it creating a shadow that reveals the atoms’ distribution On Earth gravity pulls at the atoms the moment they are released typically giving physicists just 10 to 20 milliseconds to make their measurements before the BEC crashes to the bottom of the vacuum chamber In the weightlessness of orbit a BEC should hover for up to 10 seconds before lingering gas in the vacuum chamber warms it up Sackett says allowing time for measurements that can’t be made on Earth Working in orbit should also push atoms to lower temperatures In making a BEC the final step begins with the atoms trapped in a magnetic field Physicists ramp down the magnetic field so that the trap becomes weaker and wider allowing the gas to expand and cool—just as a can of spray paint gets cold when the gas inside decompresses In orbit the trap can get weaker and bigger without losing the atoms enabling the gases to attain even lower temperatures Such weightlessness has been mimicked fleetingly on the ground Since 2007 a multi-institutional team working at the Center of Applied Space Technology and Microgravity in Bremen Germany has dropped its reusable cold atom experiments down a 146-meter tower into a bed of polystyrene pellets The plunge produces nearly 5 seconds of weightless free fall in which to work—and twice as long if researchers catapult the experiment up the tower and allow it to fall back to Earth Those few seconds enabled the team to reach temperatures of 50 picokelvins the coldest ever attained says Ernst Rasel a physicist at the Gottfried Wilhelm Leibniz University of Hanover in Germany and leader of the QUANTUS collaboration (The acronym comes from the German for "quantum gases under weightlessness") Earlier this year QUANTUS researchers launched their apparatus on a sounding rocket from Kiruna Sweden Rising to an altitude of more than 240 kilometers the rocket flight offered 6 minutes of free fall During that time the automated machinery performed 85 distinct experiments Rasel says including producing the first BEC in space The ISS however will give CAL far more time—a year or longer—letting users do even more For starters CAL physicists aim simply to try to reach the lowest temperatures possible which might allow delicate new quantum effects to emerge Researchers are confident they can dip down to 100 picokelvins and possibly lower Sackett says That may not be quite as low as the QUANTUS team claims in its drop-tower result But the QUANTUS team can perform just three runs a day whereas CAL can perform experiments continuously Out in the coldIn 2018 NASA’s Cold AtomLaboratory (CAL) will rocket tothe International Space Station(ISS) There the $70 milliondevice will chill clouds of atomsto less than a billionth of adegree above absolute zero andcreate Bose-Einstein condensates (BECs) in which the atoms behave like a single quantum wave of matter and can flow without any resistance In orbit the atoms will hover weightlessly giving physicists more time to perform experiments 2 The atom chip takes overAfter the atoms are chilled to about 100 microkelvins they’re transferred to a purely magnetic trap created by electric currents in the atom chip 1 Magneto-optical trappingWithin a magnetic trap lasers in six directions counteract the motion of the atoms slowing and cooling them The complete packageThe size of an ice chestCAL will contain the lasersmagnetic coils pumps andvacuum chamber

CAL employs a multistep process within a vacuum chamber about the size of a stick of butter A microchip known as an “atom chip” drives the final cooling steps 4 A chilling expansionTo push temperatures lower the magnetic trap is weakened The cloud of atoms expands and cools while remaining a BEC 3 Evaporative coolingLike blowing on hot soup radio waves from the chip nudge the hottest

chip Laser CAL science module ISS US Destinymodule/CAL Vacuumchamber Atoms transfer to atom chip Radiowaves C Bickel/Science In another experiment Nathan Lundblad a physicist at Bates College in Lewiston Maine and colleagues hope to make hollow shells of BECs something that gravity squashes on Earth The bubbles can be fashioned by applying radio waves of the right frequency to a BEC Lundblad explains and at first researchers hope to simply jiggle the bubbles and see how they react But the shells might also enable them to probe the wave nature of the BEC in a new way Mathematical consistency demands that the undulating quantum wave in the BEC wrap around the sphere and merge smoothly with itself As it does so it might generate tiny whirlpools called vortices Physicists have already produced vortices by spinning a BEC In Lundblad’s experiment however vortices would emerge in a new way—through the interplay of the quantum wave and the geometry of the bubble Others on the CAL team plan to probe an odd bit of quantum mechanics known as the Efimov effect that enables certain atoms to form weakly bound three-atom molecules even though no two atoms will stick together The molecules are the atomic equivalent of the Borromean rings a topological curiosity in which three rings intertwine so that removing any one ring causes the other two to fall apart To create the molecules JILA’s Cornell and Peter Engels and Maren Mossman of Washington State University in Pullman will apply a magnetic field to ultracold atoms of potassium-39 The gas won’t be dense enough to form a BEC but at certain magnetic field strengths the isolated atoms should be coaxed into forming three-atom molecules The effect has been seen on Earth but theory predicts that the molecules will form break up and reform at successively stronger magnetic fields The size of molecules should grow each time by a factor of 227 Cornell and colleagues aim to spot the second Efimov state in which the molecules become giants about the size of bacteria To do that will require letting the gas expand until it is 1/1000 as dense as in earlier experiments—something that would be difficult on Earth "It’s going to be doubly hard because we don’t get to hover around [the experiment] with an army of graduate students" Cornell says A 146-meter-tall drop tower in Bremen Germany offers nearly 5 seconds of free fall enough to cool a Bose-Einstein condensate to a record 50 picokelvins ZARM University of Bremen Perhaps CAL’s biggest goal is a type of experiment called atom interferometry Laser light can split the quantum wave of a BEC into two halves that move apart and recombine Thanks to the weirdness of quantum theory that splitting means that each atom in the BEC literally takes both paths at once If the split paths are separated vertically one path will be infinitesimally farther from Earth giving it slightly more gravitational energy than the other path and causing the quantum wave to undulate slightly faster along that path As a result when the waves merge they will interfere with each other to create a rippled density distribution in the BEC The pattern should reveal exactly how much the atoms accelerate under gravity as they orbit Earth If precise enough an orbiting atom interferometer could have many scientific applications Atom interferometers might be used in spacecraft as inertial navigation systems that would be more accurate than current devices which rely on laser gyroscopes And by testing the effect of gravity on BECs of two different types of atoms an atom interferometer could test the principle that all objects no matter their weight or composition accelerate at the exact same rate under gravity’s pull—as Galileo Galilei supposedly demonstrated by dropping balls of different materials off the Leaning Tower of Pisa in Italy That "equivalence principle" now serves as the cornerstone of Albert Einstein’s theory of gravity general relativity and physicists are keen to test it in as many ways as they can Because of equipment problems however CAL won’t be able to do atom interferometry right away To produce BECs CAL’s developers at JPL are using a system made by ColdQuanta Inc, such as when he painted the wrecks of East India Company’s ships after having heard or read accounts of them.
