Colloidal quantum dot laser diodes are just around the corner

Los Alamos scientists have incorporated meticulously engineered colloidal quantum dots into a new type of light emitting diodes (LEDs) containing an integrated optical resonator, which allows them to function as lasers. These ...

Divorce in a one-dimensional world

In everyday objects, there is no left without right or front without back. Just as inseparable seem to be the electron's electric charge and its "spin." But in a strictly one-dimensional quantum world, both quantum properties ...

Laser physics: At the pulse of a light wave

Physicists in the Laboratory for Attosecond Physics at Ludwig-Maximilians-Universitaet (LMU) in Munich and at the Max Planck Institute for Quantum Optics (MPQ) have developed a novel type of detector that enables the oscillation ...

Has physics ever been deterministic?

Researchers from the Austrian Academy of Sciences, the University of Vienna and the University of Geneva, have proposed a new interpretation of classical physics without real numbers. This new study challenges the traditional ...

Evading Heisenberg isn't easy

EPFL researchers, with colleagues at the University of Cambridge and IBM Research-Zurich, unravel novel dynamics in the interaction between light and mechanical motion with significant implications for quantum measurements ...
