Innovations in microscale electronics, medicine, combustion and scores of other technologies depend on understanding and predicting the behavior of electricity on the smallest of length scales.  New research from UBC's Okanagan campus, recently published in Nature Communications, may have uncovered the key to one of the darkest secrets of light.  But an international group led by Prof. Beena Kalisky and Prof. Aviad Frydman, from the Department of Physics and the Institute for Nanotechnology at Bar-Ilan University in Israel, has succeeded in imaging quantum fluctuations for the first time.  To tame chaos in powerful semiconductor lasers, which causes instabilities, scientists have introduced another kind of chaos.  An international team of scientists developed the world's first anti-laser for a nonlinear Bose-Einstein condensate of ultracold atoms.  A kiwi physicist has discovered the energy difference between two quantum states in the helium atom with unprecedented accuracy, a groundbreaking discovery that contributes to our understanding of the universe and space-time and rivals the work of the world's most expensive physics project, the Large Hadron Collider.  Physicists and material scientists have succeeded in constructing a motor and an energy storage device from one single component.  Heat pipes are devices to keep critical equipment from overheating. They transfer heat from one point to another through an evaporation-condensation process and are used in everything from cell phones and laptops to air conditioners and spacecraft.  Now, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed an algorithm that can discover and optimize these materials in a matter of months, relying on solving quantum mechanical equations, without any experimental input.  Researchers at the University of Illinois at Urbana-Champaign have developed a new technology for switching heat flows 'on' or 'off'.  Thermoelectric materials can use thermal differences to generate electricity. Now there is an inexpensive and environmentally friendly way of producing them with the simplest tools: a pencil, photocopy paper, and conductive paint.
