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 immersed in a Bose-Einstein condensate (BEC), we...

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 rotation.

Exploring synthetic quantum matter in superconducting circuits

Exploring synthetic quantum matter in superconducting circuits
Mon, Jan 21, 2019, 1:00 pm

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.

Atomic Physics Seminar | Nathan Schine, UChicago | "Quantum Hall Physics with Photons"

Atomic Physics Seminar | Nathan Schine, UChicago | "Quantum Hall Physics with Photons"
Thu, Jan 17, 2019, 3:00 pm

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.

The LHC has helped complete the Standard Model; it has also left open some gaping holes. Among these are any prediction of dark matter, a sufficient source for the matter, and antimatter imbalance in the universe or an adequate explanation of neutrino mass.

Atomic Physics Seminar, Richard Parker, U of Chicago, "First Measurement of the Atomic Electric Dipole Moment of 225Ra"
Fri, Mar 20, 2015, 12:00 pm to 1:30 pm
The radioactive radium-225 (225Ra) atom is a favorable system to search for a permanent electric dipole moment (EDM). Due to its strong nuclear octupole deformation and large atomic mass, 225Ra is particularly sensitive to interactions in the nuclear medium that violate both time-reversal

We measure the shear viscosity in a two-component Fermi gas of atoms, tuned to a broad s-wave Feshbach resonance. At resonance, the atoms strongly interact and exhibit universal behavior, where the equilibrium thermodynamic properties and the transport coefficients are universal functions of the density $n$ and temperature $T$.

Several studies in experimental and theoretical magnetic resonance are presented. The longitudinal relaxation of solid $^{129}$Xe is shown to have an unexpected structural dependence from experiments that provide previously unattainable reproducibility; first-principles theories that attempt to describe the observed data are analyzed.

Rare-earth ions in the solid state are a prime candidate for quantum memory and other quantum information applications, due to their strongly shielded optical transitions. These same optical transitions allow for direct optical manipulation of nuclear-spin transitions. This is of interest for studying interactions in solids, as well as for long-...
