Abstract: The space-time duality between Fresnel diffraction and narrowband dispersion has been the basis for the development of successful temporal imaging systems employing “time lenses” which produce quadratic phase modulation on propagating optical wavepackets.
Dissipative crystals of matter and light - from self-oscillating pumps to dissipation-stabilized phases
Abstract:
Precise control of quantum states of matter and innovative laser technology are revolutionizing the performance of atomic clocks and metrology, providing opportunities to observe new quantum phenomena and explore fundamental physics. In this talk I will present the development of an optical atomic clock in the historical context of JILA’s science.

Abstract: Simultaneously measuring the nanoscale motion and forces that molecular machines generate provides insights into how they work mechanically to fulfill their cellular function. To study these machines, we developed germanium nanospheres as probes for optical tweezers. With these high–refractive index nanospheres, we have improved the resolution of optical tweezers and discovered that the motor kinesin takes 4-nanometer substeps. Further, instead of detaching from their microtubule track under load, motors slid back on it, enabling rapid re-engagem
Abstract: Cavity quantum electrodynamics (QED) is one of the most powerful framework to observe and leverage quantum phenomena. While it has been thoroughly studied for simple quantum systems such as two-level systems or harmonic oscillators, it has only recently become available for complex, correlated quantum many-body systems. In the last five years, we have developed systems combining cavity QED with ultra-cold Fermi gases [1].
Abstract:
Quantum control of mechanical motion has been achieved in a surprising range of platforms in the past decades. These mechanical quantum systems have both piqued the curiosity of physicists, and enabled new approaches to difficult tasks in manipulating quantum information.
Abstract: Ultracold polar molecules, which have complex internal state structures and dipole moments tunable with external electric fields, are a promising system for studying many-body physics. Producing degenerate molecules and observing quantum effects has been prevented by high initial temperatures and rapid loss from chemical reactions. In this talk, I describe the creation of degenerate potassium-rubidium (KRb) molecules by pairing in an atomic mixture.
