Current knowledge of such s ystems is limited on multiple fronts: experimentally\, these materials are often difficult to fabricate in laboratory settings\, and numeric al simulations become intractable as the number of particles approache s meaningful values. In the spirit of Feynman\, physicists can model diverse phenomena\, from high-temperature superconductivity to quantum spin liquids\, using analog quantum simulation. My research explores emergent quantum phenomena in pristine systems made of atoms\, molecu les\, and electromagnetic fields. In particular\, ultracold molecules are a promising platform due to their tunable long-range interactions and large set of internal states. However\, this nascent platform req uires new experimental techniques to create\, control\, and probe mole cular systems.
\nI will report on efforts to create ultracold polar molecules\, coherently manipulate their internal levels\, and demonst rate second-scale coherence times in a molecular ensemble. To leverag e the long-range\, anisotropic dipolar interactions\, we engineer dipo lar collisions in a bulk ensemble using the technique of microwave dre ssing. Upon loading polar molecules into a 2D optical lattice\, we st udy dynamics and thermalization in a variety of spin models relevant t o quantum magnetism. Toward that end\, we develop a novel readout mod ality – quantum gas microscopy – to perform site-resolved fluoresc ence imaging\, enabling the measurement of quantum correlations and en tanglement. The techniques presented here establish ultracold molecul es as a compelling platform for quantum science and technology.
