    Aug 16, 2024Here, we laser-couple diatomic molecules of highly excited Rydberg atoms, so-called Rydberg macrodimers, to a continuum of free motional states. Enabled by their small vibrational eigenfrequencies, we achieve the regime of strong continuum couplings and observe the appearance of new resonances.

    Here, we laser-couple diatomic molecules of highly excited Rydberg atoms, so-called Rydberg macrodimers, to a continuum of free motional states. Enabled by their small vibrational eigenfrequencies, we achieve the regime of strong continuum couplings and observe the appearance of new resonances.
  4. Held together by dipolar forces across distances of hundreds of nanometers, macrodimers exhibit a vibrational spectrum characteristic of diatomic molecules. For covalently bound molecules, coherent control over the bound state is limited to strong external fields such as available in pulsed lasers [ 16, 17, 18].
  5. Jan 10, 2024The coupling of an isolated quantum state to a continuum is typically associated with decoherence and decreased lifetime. Here, we demonstrate that Rydberg macrodimers, weakly bound pairs of Rydberg atoms, can overcome this dissipative mechanism and instead form bound states with the continuum of free motional states. This is enabled by the unique combination of extraordinarily slow ...

    Aug 1, 2024Here, we laser-couple diatomic molecules of highly excited Rydberg atoms, so-called Rydberg macrodimers, to a continuum of free motional states. Enabled by their small vibrational eigenfrequencies, we achieve the regime of strong continuum couplings and observe the appearance of new resonances.
  7. Here, we explore the continuous transition from the familiar weak continuum coupling to strong couplings using Rydberg macrodimers, see Fig. 1 (a). Macrodi-mers are giant molecules of two atoms, both excited to their Rydberg states [10-15]. Held together by dipolar forces across distances of hundreds of nanometers, mac-rodimers exhibit a vibrational spectrum characteristic of diatomic ...

    Jan 10, 2024For atoms arranged on a lattice, we predict the strong continuum coupling to even stabilize molecules consisting of more than two atoms and find first signatures of these by observing atom loss correlations using a quantum gas microscope.

    A Rydberg optical Feshbach resonance is demonstrated, which is based on ultra-long-range Rydburg molecules, which opens up a class of optical Fshbach resonances with a plenitude of available lines for many atomic species and the possibility to further increase the performance by carefully selecting the underlying Ryd Berg state.

    Rydberg-state excitation of atoms in strong infrared laser fields provides a new complementary aspect of the perspective of atom-strong field interactions. In this article, we perform an experimental and theoretical study on the corresponding process of diatomic molecules, and .
