Atoms and molecules in the ultracold regime have emerged as promising platforms for quantum simulation of strongly-correlated matter.  In this talk, I will describe recent progress on two fronts to study quantum many-body physics with ultracold gases.  First, using ultracold fermionic atoms…

Spin-exchange pumped noble gas comagnetometers consist of two or more co-located ensembles of noble gas atoms whose nuclei are polarized by spin-exchange collisions with polarized alkali atoms. Such devices been used to place upper bounds on fifth forces and Lorentz violations and for the measurement of inertial…

Dark  matter  and  dark  energy are  the  most  abundant  yet  mysterious  substances  in  the  Universe. Axions  and  axion-like  particles (ALP) have emerged as theoretically well-motivated dark-matter candidates. Ultrahigh sensitivity magnetometers play important roles in dark matter searches. Here we demonstrate…

Superconducting circuits have emerged as a competitive platform for quantum computation, satisfying the challenges of controllability, long coherence and strong interactions. Here we apply this toolbox to a different problem: the exploration of strongly correlated quantum materials made of microwave photons. We develop a versatile recipe that…

Topological materials have recently become a distinct focus in condensed matter physics, appearing famously in the quantum Hall effect and topological insulators. In these materials, certain essential properties are governed by ‘topological invariants,’ quantities insensitive to local perturbation or manipulation. As such, understanding and…
