Saturday Physics for Everyone
|Title||Saturday Physics for Everyone: Ultracold Physics: Creating Quantum Matter at the Coldest Temperatures in the Universe|
|Speaker||Professor Brian DeMarco|
|Time:||10:15 a.m. - 11:30 a.m.|

|Originating Calendar:||Physics - Saturday Physics for Everyone|
The coldest objects in the universe are gases of atoms that are trapped and cooled using lasers in labs located on Earth. I will talk about how we achieve these ultra-low temperatures, just trillionths of a degree above absolute zero. In this ultra-cold regime, the quantum nature of matter is inescapable, and the atoms behave like waves. I will discuss how we use these quantum matter waves to study one of the most important outstanding questions in physics: how new phenomena like superfluidity emerge from collections of interacting quantum particles.
