DESCRIPTION:Quantum simulation with ultracold atoms is a powerful platform 
 for understanding the microscopic foundations underlying fractional quantu
 m Hall phases\, where the interplay between particle interactions and a ma
 gnetic field gives rise to wave functions with distinctive correlations. T
 he single-site control and imaging capabilities of a quantum gas microscop
 e allow us to probe these correlations directly. Using artificial gauge fi
 elds and a bottom-up adiabatic ramp to the ground state\, we are able to c
 reate and study quantum hall states through their characteristic correlati
 on signatures. \n\n\nOur latest project applies this process to the Pfaffi
 an state\, an especially sought-after topological phase predicted to host 
 features like non-abelian anyonic excitations and p-wave pairing. We prepa
 re the state using three atoms on a 5x5 grid\, and measure density correla
 tions consistent with this pairing picture as described by the Moore-Read 
 wave function: a pronounced suppression of local three-body correlations r
 elative to the normal state\, but a much weaker suppression of two-body co
 rrelations\, representing a state where two particles form a pair that the
  third one avoids. We also implement a transport-style probe analogous to 
 traditional condensed matter Hall-drift measurements by quenching the conf
 inement and measuring the center-of-mass drift in response to a weak appli
 ed force. This drift velocity agrees with theory\, establishing a proof-of
 -concept for connecting the properties of our small system to the larger c
 ounterparts. Together\, these measurements represent an important step for
 ward in making artificial FQH states accessible to cold atom experiments\,
  paving the way towards engineering larger states and measuring more compl
 icated topological observables.
