CUA Seminar – Waseem Bakr: Quantum gas microscopy of correlated systems with new ingredients: kinetic frustration and dipolar interactions
Location:Harvard Jefferson 250
Waseem Bakr, Princeton
Ten Minute Talk:"Dipolar Hubbard Model" by
Sooshin Kim
Quantum gas microscopy has revolutionized quantum simulation with ultracold atoms in optical lattices. So far, it has mostly been applied in the context of the “plain-vanilla” Hubbard model on the square lattice relevant to the high-temperature superconducting cuprates. In this talk, I will report on the microscopy of correlated systems with new ingredients. I will describe programmable optical lattices, focusing on the case of the triangular lattice which introduces spin and kinetic frustration. We observe a novel type of “high-temperature” magnetic polaron in this system, stabilized by kinetic frustration. Next, I will describe our development of a molecular quantum gas microscope that allowed us to study correlated systems with dipolar interactions. There, I will report on the study of the dynamical evolution of spin correlations in out-of-equilibrium dipolar quantum spin models. Finally, I will discuss prospects for exploring dipolar Hubbard models realized with molecules.
