Nanodots reveal a quantum phase transition

Nanoscale devices could be used to observe quantum phase transitions, say researchers in France. Franck Balestro of the Joseph Fourier University and the Institut Néel, CNRS, in Grenoble and colleagues made a quantum-dot device to observe "quantum criticality" – a phenomenon thought to govern the properties of high-temperature superconductors among other materials. The result may help advance the field of molecular spintronics and have applications in quantum computing.
