Taking moody with ultracold atoms

On a recent warm, balmy morning during Boulder’s metropolitan airport, CU Boulder production highbrow and JILA Fellow Dana Anderson stood on a tarmac with his colleagues scheming to take to a skies with some very, really cold atoms.

Perched on a wing of a single-propeller airplane, Anderson leaned inside a fuselage to make a few final adjustments on a apparatus tucked into a behind seat. The setup is usually about a distance of a stereo amp, though harnesses a marvel of physics: a little cloud of around 10 million particular atoms, cooled to nearby comprehensive 0 and sealed in place by lasers with a force of about 1,000 Gs—nearly 100 times a g-force that a tellurian roving in a supersonic warrior jet would experience.

Anderson hopes that this ethereal magneto-optical trap, or MOT, will infer clever adequate to reason adult to vibrations and radio signals during a roughly 75-minute roundtrip moody to Cheyenne, Wyoming. Ultracold atoms are typically combined underneath rarely tranquil laboratory conditions. The day’s demonstration is one of the initial famous try to take a MOT airborne as newcomer on an typical municipal airplane.

“It’s exciting, and that’s because we do it,” said Anderson, a stream chair of JILA, a corner hospital of CU Boulder and a National Institute of Standards and Technology.

The scholarship behind precipitated matter production is not code new by any means, though a operation of intensity applications has usually grown in new decades. Eric Cornell and Carl Wieman of CU Boulder and JILA common a 2001 Nobel Prize in Physics for a successful origination of a Bose-Einstein condensate (BEC), a new form of matter in that bosons are cooled down to occupy their lowest quantum state.

Anderson, who collaborated with Cornell and Wieman, has spent years researching how these ultracold atoms competence be integrated into next-generation aerospace sensors and navigation devices. When atoms are cooled to nearby comprehensive zero, they start to take on some-more elemental attraction due to clever communication with sobriety and captivating fields.

Once cooled and trapped in place by a lasers in a MOT environment, these ultracold atom populations turn useful for inertial sensing, providing information homogeneous to that of an accelerometer (which measures quickness change in a true line) and a gyroscope (which measures rotation). Both are essential collection for aviation.

Atomic inertial sensing, once softened and polished for travel, would be deliberate distant some-more arguable and accurate than a now ubiquitous GPS technology, that relies on satellite information to pinpoint location.

“GPS is ethereal and can be tangled easily, possibly intentionally or accidentally,” Anderson said. “You’d like to be means to know where you’re going but it . . . we’re not nonetheless during a indicate where we could fly from Boulder to JFK airfield with a eyes closed.”

In 2007, Anderson founded ColdQuanta, a Boulder-based startup company, to serve his ultracold atom investigate and emanate blurb applications for a technology. This latest mini-MOT combined by ColdQuanta was engineered mostly from glass, ceramic and silicon rather than steel in sequence to emanate a section tiny adequate to transport in a plane—no easy pattern feat.

Vescent Photonics, a JILA spinoff association that creates electro-optic technologies, supposing a laser components for a MOT.

Anderson hopped into a cockpit and put on a headset, prepared to fly the plane to Cheyenne while his colleagues Jaime Ramirez-Serrano and Janet Duggan, both ColdQuanta scientists, float along to guard a equipment. After a flight, a researchers devise to investigate a information and see how a MOT hold adult in sequence to continue tweaking a design.

With final preparations complete, a craft is privileged for takeoff. Amid cheers from onlookers representing a systematic staffs of both ColdQuanta and Vescent, Anderson fired up a engine. The tiny craft taxied to a corner of a runway and took off uniformly into a morning sunshine.
