Absolutely Negative (2013)

unapi

In the mid-1 800s, Lord Kelvin postulated that nothing could be colder than the temperature of absolute zero degrees, when all atomic particles are at rest. But in the mid-20th century, physicists realized that the mathematics governing absolute temperature indicated that subzero temperatures were possible and, soon after that they were demonstrated. Recently, the first subzero Kelvin temperatures were achieved for particles in motion. Temperature depends on the kinetic and potential energies of atoms and on the interactions between them. By using an optical lattice of laser beams, atoms could still move, but their kinetic and potential energies were held in check. Researchers controlled interactions between the atoms with magnetic fields. This discovery has implications for technology, because negative temperatures could result in more efficient heat engines, and for cosmology, because negative temperatures may explain properties of dark energy.
