New Approach A Step Closer to Airport Scanners that can Distinguish Aspirin from Explosives

For more than 30 years, scientists have been trying to harness the power of terahertz radiation. Tucked between microwaves and infrared rays on the electromagnetic spectrum, terahertz rays can penetrate clothing, plastic, and human tissue, but they're thought to be safer than x-rays.

Physicists Use Laser Light to Create "Synthetic Magnetism"

For the first time, physicists have used laser light to create "synthetic magnetism," an exotic condition in which neutral atoms suddenly begin to behave as if they were charged particles interacting with a magnetic field -- even though no such field is present and the atoms have no charge.

Physicists Reveal New Insight and Facets of the Effect of Non-Resonant Coupling

Future applications of quantum information technology, e.g., ultimately secure data transfer protocols, will be based on data encryption by sequences of single photons, i.e., the smallest and therefore indivisible quanta of light. As possible candidates for such special kinds of light sources, so-called quantum emitters inside a micro-resonator can be used.

Adaptable Technology Opens Door to Wide Range of Applications in Chemical Detection

An international team of applied scientists from Harvard, Hamamatsu Photonics, and ETH Zürich have demonstrated compact, multibeam, and multi-wavelength lasers emitting in the invisible part of the light spectrum (infrared). By contrast, typical lasers emit a single light beam of a well-defined wavelength.
