• Title: Clock Transitions Versus Bragg Diffraction in Atom-interferometric Dark-matter Detection
• Authors: Daniel Derr and Enno Giese
• Abstract summary: We study the effects of dark matter on the internal atomic structure and the atoms' motion. We show that the atomic transition frequency depends on the mean coupling and the differential coupling of the involved states to dark matter. For sensors generated by state-preserving diffraction mechanisms like Bragg diffraction, the mean coupling modifies only the motion of the atom as the dominant contribution.

• Abstract: Atom interferometers with long baselines are envisioned to complement the ongoing search for dark matter. They rely on atomic manipulation based on internal (clock) transitions or state-preserving atomic diffraction. Principally, dark matter can act on the internal as well as the external degrees of freedom to both of which atom interferometers are susceptible. We therefore study in this contribution the effects of dark matter on the internal atomic structure and the atoms' motion. In particular, we show that the atomic transition frequency depends on the mean coupling and the differential coupling of the involved states to dark matter, scaling with the unperturbed atomic transition frequency and the Compton frequency, respectively. The differential coupling is only of relevance when internal states change, which makes detectors, e.g., based on single-photon transitions sensitive to both coupling parameters. For sensors generated by state-preserving diffraction mechanisms like Bragg diffraction, the mean coupling modifies only the motion of the atom as the dominant contribution. Finally, we compare both effects observed in terrestrial dark-matter detectors.

  We show that when a single atom tunneling in a double well is coupled to an optical ring cavity, the interference phenomena arise. Being driven by an external laser in the dispersive regime, the field emitted by the atom into the cavity exhibits an interference pattern. Our work opens ways to manipulate photons with controllable external states of atoms for quantum information applications.

  One of the hallmarks of interacting systems is the formation of multi-particle bound states. We develop a high fidelity parameterizable fSim gate that implements the periodic quantum circuit of the spin-1/2 XXZ model. By placing microwave photons in adjacent qubit sites, we study the propagation of these excitations and observe their bound nature for up to 5 photons.

• Atom Interferometer Tests of Dark Matter [0.0]
  We propose to use atom interferometers to detect a light dark matter subcomponent at sub-GeV masses. We describe the decoherence and phase shifts caused by dark matter scattering off of one "arm" of an atom interferometer. We find that, for a mediator mass $m_phi=10-10m_chi$, future atom interferometers could close a gap in the existing constraints on nuclear recoils.

• Emergent dark states from superradiant dynamics in multilevel atoms in a cavity [0.0]
  We find that multilevel atoms can harbour eigenstates that are perfectly dark to cavity decay even within the subspace of permutationally symmetric states (collective Dicke manifold) Remarkably, the superradiant decay of multilevel atoms can end up stuck in one of these dark states, where a macroscopic fraction of the atoms remains excited. This opens the door to the preparation of entangled dark states of matter through collective dissipation useful for quantum sensing and quantum simulation.
