It was reported in ScienceDaily that the researchers from Ohio State University have developed a new strategy to overcome one of the major obstacles to a grand challenge in physics, that intimately linked to the making of light crystals.
Before, in the year of 2008, the researchers from Defense Advanced Research Projects Agency (DARPA) had an ambitious problem called “optical lattice”. It has been known that this thing affected the simulation of exotic materials and answer fundamental questions in physics, but the team have been unable to make the atoms cold enough for their experiments to work.
Then, Ohio State university physicist Tin-Lun Ho and doctoral student Qi Zhou present a potential solution, using a new method that cools the atoms in an optical lattice by literally squeezing the heat out of them and into a surrounding BEC.
Three-dimensional cubic structure made of laser light which contains many smaller cubes hopefully can create an adjustable crystal out of laser light, and will be able to emulate different solid materials.
