Toward a continuous atom laser

Ever since its invention, the laser has been an invaluable tool in physics. It is expected that an atom laser - with the light waves replaced by the quantum waves of atoms - could have similarly important applications, for ...

Two teams independently test Tomonaga–Luttinger theory

(Phys.org)—Two teams of researchers working independently of one another have found ways to test aspects of the Tomonaga–Luttinger theory that describes interacting quantum particles in 1-D ensembles in a Tomonaga–Luttinger ...

'Quantum leap' for Liverpool

Physicists from the University of Liverpool have made a huge step forwards towards building a novel experiment to probe the "dark contents" of the vacuum. What we see, normal matter and light, only accounts for a about 5% ...

Quantum-physical model system

Two researchers at Heidelberg University have developed a model system that enables a better understanding of the processes in a quantum-physical experiment with ultracold atoms. Using computer-assisted methods, Prof. Dr ...

Quantum optical sensor for the first time tested in space

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments ...
