Using quantum gas composed of potassium atoms scientists have managed to reach sub-absolute zero temperature. The temperature dropped a “few billionths of a Kelvin” under absolute-zero with a magnetic field tweak.
“This suddenly shifts the atoms from their most stable, lowest-energy state to the highest possible energy state, before they can react. It’s like walking through a valley, then instantly finding yourself on the mountain peak,” said Ludwig Maximilian University’s Ulrich Schneider.
The potassium atoms were arranged in a lattice formation by the reversed magnetic field in combination with lasers. Instead of repelling, the magnetic field alteration caused the atoms to attract.
This could potentially lead to new matter being created. Theoretical physicist, Achim Rosch, says “High-energy states are stabilized in sub-absolute zero temps, for example, while possibly reacting in non-standard ways,” where “atom clouds could drift upwards in what seems to be a violation of gravity.”
