Fluctuating superconductivity in organic molecular metals close to the Mott transition

Article Abstract:

The fluctuating superconductivity occurring substantially above the transition temperature might be induced by the proximity of a Mott-insulating state. The vortex-Nerst effect has shown that a fluctuating regime has developed as t/U (t is the tight-binding transfer integral characterizing metallic bandwidth and U the on-site Coulomb repulsion) has decreased and the role of Coulomb correlations has increased.

Quantum physics: Indistinguishable from afar

Article Abstract:

Physicists have shown that two ensemble of atoms, Bose-Einstein condensates, can reveal their indistinguishability, even when they are some distance apart. The experiment is an interesting demonstration of a fundamental aspect of quantum physics, indistinguishability, and it has also shown a state of unprecedented experimental control of coherent light and mater waves.
