Nobel Laureate Wolfgang Ketterle, MIT, will explore: “The coolest use of light – using light forces to study the coldest matter in the universe.“
Light has many important properties and applications. I will explain that light exerts forces on particles and objects. These forces deflect the tails of comets. They are used in the form of optical tweezers to manipulate cells and DNA in biological samples, and they allow the trapping of atoms. Laser light can cool matter to temperatures close to absolute zero. In this regime, new materials with novel properties are observed.
