In a recent experiment, a microwave resonator, a circuit that supports electric signals oscillating at a resonance frequency, is coupled to the vibrations of a metallic micro-drum. By actively cooling the mechanical motion close to the lowest energy allowed by quantum mechanics, the micro-drum can be turned into a quantum reservoir - an environment that can shape the states of the microwaves.
Ormia ochracea's sense of directional hearing is second to none in the animal kingdom. But, according to new research, what makes its hearing so incredible may also complicate efforts in using it as a model for new technology, including hearing aids.
By precisely measuring the entropy of a cerium copper gold alloy with baffling electronic properties cooled to nearly absolute zero, physicists have gleaned new evidence about the possible causes of high-temperature superconductivity and similar phenomena.
When building with molecules, it is important to understand how they stick to each other. The problem is that the methods used to measure this are themselves an influencing factor on the process. A new study presents a method that excludes this influence.
