• Title: Confinement-induced field-linked states of ultracold polar molecules
• Authors: Reuben R. W. Wang, John L. Bohn,
• Abstract summary: We predict the existence of stable bound states between pairs of ultracold diatomic molecules with the aid of a static electric field and 1D harmonic confinement. With the diatomic molecules bound at distances a fraction of the dipolar length scale, these complexes allow for explorations of polyatomic chemistry and Fermi gas superfluid pairing.

• Abstract: We predict the existence of stable bound states between pairs of ultracold diatomic molecules with the aid of a static electric field and 1D harmonic confinement. We focus on collisions of NaK-NaK identical fermions, for which we find that currently achievable experimental parameters allow the observation of these confinement-induced field-linked bound states as scattering resonances. The bound state is highly stable with lifetimes estimated to be tens of seconds long. With the diatomic molecules bound at distances a fraction of the dipolar length scale, these complexes allow for explorations of polyatomic chemistry and Fermi gas superfluid pairing.

  We consider ultralong-range polyatomic Rydberg molecules formed by combining a Rydberg cesium atom and a ground-state RbCs molecule. We explore the regime where the charge-dipole interaction due to the Rydberg electron with the diatomic polar molecule couples the quantum defect Rydberg states Cs(ns) to the nearest hydrogenic manifold.

• Rydberg molecules bound by strong light fields [0.0]
  We show that Rydberg macrodimers, weakly bound pairs of Rydberg atoms, can form bound states with the continuum of free motional states. This is enabled by the unique combination of extraordinarily slow vibrational motion in the molecular state and the optical coupling to a non-interacting continuum. Our results present an intriguing mechanism to control decoherence and bind multiatomic molecules using strong light-matter interactions.

  Quasiparticles are emergent excitations of matter that underlie much of our understanding of quantum many-body systems. We take advantage of the clean setting of homogeneous quantum gases and fast radio-frequency control to manipulate Fermi polarons. We measure the decay rate and the quasiparticle residue of the driven polaron from the Rabi oscillations between the two internal states.

  We stabilize a bosonic gas of strongly dipolar NaCs molecules against inelastic losses via microwave shielding. We also measure high elastic scattering rates, a result of strong dipolar interactions, and observe the anisotropic nature of dipolar collisions. This work is a critical step towards the creation of a Bose-Einstein condensate of dipolar molecules.

  We consider the cooperative spontaneous emission of a system of two identical atoms, interacting with the electromagnetic field in the vacuum state. Using time-dependent theory, we investigate the spectrum of the radiation emitted by the two-atom system. We show that it is modulated in time, and that the presence of the oscillating mirror can enhance or inhibit the decay rate.
