Minute crystals, many thousand times smaller than a particle of dust, dressed with the right kind of imperfections, adjust their electronic properties to convert energy into heat, an important attribute for potential use in smart materials for energy, health and sensors.
"Observation of extremely efficient terahertz generation from mid-infrared two-color laser filaments" was published at Nature Communications
A major frontier in strong field laser physics and nonlinear optics is the interaction of powerful terahertz (THz) pulses with matter.
The BEC and Matterwaves group of Wolf von Klitzing have created a novel atomtronic accelerator ring for neutral atoms. It accelerates Bose-Einstein Condensates at hypersonic speeds and to transport them over record distances. This will enable novel quantum sensors for gravity and rotation.
