Drawing a line between quantum and classical: Bell’s Inequality fails test as boundary

Drawing a line between quantum and classical: Bell’s Inequality fails test as boundary

July 21, 2015

The best guide to the boundary between our everyday world and the “spooky” features of the quantum world has been a theorem called Bell’s Inequality, but now a new paper shows that we understand the frontiers of that quantum world less well than scientists have thought.

Funding aimed at fusion energy awarded to Laboratory for Laser Energetics, Sandia National Laboratories collaboration

Funding aimed at fusion energy awarded to Laboratory for Laser Energetics, Sandia National Laboratories collaboration

June 30, 2015

The award seeks to build upon recent successes of Sandia’s Magnetized Liner Inertial Fusion (MagLIF) concept. The concept uses a laser to heat fusion fuel contained in a small cylinder as it is compressed by the huge magnetic field of Sandia’s massive Z accelerator.

Defects in atomically thin semiconductor emit single photons

Defects in atomically thin semiconductor emit single photons

May 4, 2015

Until now, optically active quantum dots have not been observed in materials consisting of a single layer of atom, also known as 2D materials. Rochester researchers have shown how the 2D material tungsten diselenide can be fashioned into an atomically thin semiconductor that serves as a platform for solid-state quantum dots.

University of Rochester team brings sense of touch to virtual reality

April 30, 2015

Virtual reality has made huge technological gains in the last decade, but the ability to feel your surroundings is not yet a part of many mainstream virtual reality systems. A group of University of Rochester students is trying to change that by creating a jacket and gloves that allow the wearer to feel the surface […]

Generating broadband terahertz radiation from a microplasma in air

April 24, 2015

Researchers in the Institute of Optics have shown that a microplasma created by focusing intense laser pulses in air emits not only visible light, but also electromagnetic pulses at terahertz frequencies that can be used to detect complex molecules, such as explosives and drugs.
