New quantum theory heats up thermodynamic research

Researchers have developed a new quantum version of a 150-year-old thermodynamical thought experiment that could pave the way for the development of quantum heat engines.

New state of matter in one-dimensional quantum gas

As the story goes, the Greek mathematician and tinkerer Archimedes came across an invention while traveling through ancient Egypt that would later bear his name. It was a machine consisting of a screw housed inside a hollow ...

New tools 'turn on' quantum gases of ultracold molecules

JILA researchers have developed tools to "turn on" quantum gases of ultracold molecules, gaining control of long-distance molecular interactions for potential applications such as encoding data for quantum computing and simulations.

To kill a quasiparticle: A quantum whodunit

In large systems of interacting particles in quantum mechanics, an intriguing phenomenon often emerges: groups of particles begin to behave like single particles. Physicists refer to such groups of particles as 'quasiparticles'.

Probing the properties of a 2-D fermi gas

When a new physical system is created or uncovered, researchers generally study it in depth to unveil its distinctive properties and characteristics. For example, they might try to determine how the system reacts when it ...

Seeking 'soundwaves' in the superfluid order parameter

A Swinburne University of Technology study published this week examines the propagation of energy as sound waves in a quantum gas, revealing for the first time strong variations in the nature of the sound wave as a function ...

Single-atom probe uses quantum information for the first time

Sensors collect certain parameters such as temperature and air pressure in their proximity. Physicists from Kaiserslautern and a colleague from Hanover have succeeded for the first time in using a single cesium atom as a ...
