Summary form only given. We have studied the decay of the atomic coherence on atoms initially prepared in a dark state (DS) when the coherence (Raman) resonance condition between the atomic system and ...

Quantum dots beat traditional photosensitizers at their own game. They tackle reactions once thought too tough for ...

New results published in the journal Physical Review Letters detail how a specially designed metamaterial was able to tip the ...

The effect of shape anisotropy and size on the electronic structure of CdSe/ZnSe quantum dots is theoretically investigated. The quantum dot is modeled by assuming a parabolic confinement along xy ...

Researchers from the University of Technology Sydney (UTS) and the University of Manchester in the United Kingdom have ...

Scientists at UBC have devised a chip-based device that acts as a "universal translator" for quantum computers, converting delicate microwave signals to optical ones and back with minimal loss and ...

A massively parallel, direct quantum molecular dynamics method is described. The method combines a quantum trajectory (QT) representation of the nuclear wave function discretized into an ensemble of ...

Tunable spin transport in nanodevices is highly desirable to spintronics. Here, we predict existence of quantum spin Hall effects and tunable spin transport in As-graphane, based on first-principle ...

A six-count indictment filed by federal prosecutors in the Eastern District of New York charged Queens Defenders founder Lori Zeno, 64, and her husband, Rashad Ruhani, 55, with wire fraud, wire ...
