In the quantum realm, under some circumstances and with the right interference patterns, light can pass through opaque media.  Researchers at the Technion-Israel Institute of Technology have constructed a first-of-its-kind optic isolator based on resonance of light waves on a rapidly rotating glass sphere.  The micro-resonator is a two-mirror trap for the light, with the mirrors facing each other within several hundred nanometers.  "The realization of such all-optical single-photon devices will be a large step towards deterministic multi-mode entanglement generation as well as high-fidelity photonic quantum gates that are crucial for all-optical quantum information processing," says Tanji-Suzuki.  Researchers at ETH have now used attosecond laser pulses to measure the time evolution of this effect in molecules.  A new benchmark quantum chemical calculation of C2, Si2, and their hydrides reveals a qualitative difference in the topologies of core electron orbitals of organic molecules and their silicon analogues.  A University of Central Florida team has designed a nanostructured optical sensor that for the first time can efficiently detect molecular chirality-a property of molecular spatial twist that defines its biochemical properties.  UCLA scientists and engineers have developed a new process for assembling semiconductor devices.  A new experiment that tests the limit of how large an object can be before it ceases to behave quantum mechanically has been proposed by physicists in the UK and India.  Phonons are discrete units of vibrational energy predicted by quantum mechanics that correspond to collective oscillations of atoms inside a molecule or a crystal.
