Physicists Cool Microscopic Drum to Near Absolute Zero

According to a paper recently published in Nature, researchers at the National Institute of Standards and Technology (NIST) have cooled a vibrating drum to an unprecedented one-fifth of a quantum of energy, approaching the previously perceived limit of absolute zero (1). Scientists use temperature to measure the thermal motion of […]
