Ultracold Atoms in an Optical Kagome Lattice

Presented by:
Charles D. Brown II
Postdoctoral Researcher at UC Berkeley

His talk will focus on experimental studies of atoms trapped in a unique lattice made of light – an optical kagome lattice.

"To study this, we create a Bose-Einstein condensate, accelerate it, then trap it in the lattice. In doing so, we probe a special set of energy states available to the atoms, which are expected to show that the atoms’ kinetic energy does not depend on their in-lattice momentum. However, our measurements show that interactions between atoms reintroduce a momentum-dependence to the atoms’ kinetic energy by deforming the lattice away from the kagome geometry. I will also discuss details of my path as a physicist, and ways that I have tried to help address the underrepresentation of Black people in physics."
