Description

Dipolar molecules in two dimensions are a powerful platform for the study of quantum many-body physics, thanks to their long-range, anisotropic dipolar interactions. We have developed key experimental capabilities required for the study of such systems, including layer-resolved state control and detection, field-tunable dipole orientation and strength, and control of both intralayer and interlayer interactions. The interactions between layers are probed through chemical reactions mediated by exchange of rotational excitations. The reaction rate is controlled through application of an electric field gradient, revealing an interplay between the thermal energy and spin exchange. Within a layer the interactions realize a spin Hamiltonian, where the Ising and exchange interactions are controlled through electric field strength and orientation, and molecular rotational state. The interactions manifest through shifts in the rotational transition frequency and decays in the Ramsey contrast. We discuss the outlook for the platform, including a path towards creation of a spin squeezed state.
