Site-selective preparation of two-dimensional dipolar quantum gases in an optical beat-note lattice

Emil Kirilov, Marian Kreyer, Niclas H\"ollrigl, Rudolf Grimm

All-optical parametric heating in a beat-note superlattice isolates single or bilayer dipolar atom samples at the microscope focal plane.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We validate this approach by demonstrating the robust isolation of one or two atomic layers in precise coincidence with the focal plane of our objective.

C2weakest assumption

The parametric heating is assumed to be sufficiently layer-selective to remove atoms from undesired planes without significantly disturbing the target layers, and the passive stabilization via the microscope retroreflector is assumed to eliminate drifts over the relevant timescales.

C3one line summary

An all-optical beat-note lattice technique isolates single- and bilayer dipolar quantum gases at the microscope focal plane via selective parametric heating.
