Quantum Optics Seminar by Lars Wacker

Matter wave guiding through a photonic bandgap fiber

Ultracold quantum gases in one-dimensional geometries are an intriguing field of research as they allow for strong nonlinear atom-light interaction and efficient matter wave guiding. In this talk, I will discuss a project where we intend to study light-matter interaction in an extremely one-dimensional geometry. In this experiment, we realize such a configuration by coupling laser light into a hollow core photonic bandgap fiber where the resulting dipole trap efficiently confines previously cooled 85Rb atoms to a transverse dimension of 12µm and guides them along the fiber.
