Triplet Rydberg States of Aluminum Monofluoride. [PDF]

J Phys Chem A
Aluminum monofluoride (AlF) is a suitable molecule for laser cooling and trapping. Such experiments require an extensive spectroscopic characterization of the electronic structure. Two of the theoretically predicted higher lying triplet states of AlF, the counterparts of the well-characterized D$^1Δ$ and E$^1Π$ states, had experimentally not been ...

Quasi-solitons in Rydberg atom chains [PDF]

Nature Communications
Solitons—localized wave packets that travel without spreading—play a central role in understanding transport and properties of nonlinear systems. In quantum many-body systems, however, such robust excitations are typically destroyed by thermalization ...

Increasing the decoherence rate of Rydberg polaritons due to accumulating dark Rydberg atoms

Physical Review Research, 2022
We experimentally observed an accumulative type of nonlinear attenuation and distortion of slow light, i.e., Rydberg polaritons, with the Rydberg state |32D_{5/2}〉 in the weak-interaction regime. The present effect of attenuation and distortion cannot be

Long-range Rydberg-atom–ion molecules of Rb and Cs

Physical Review Research, 2021
We propose a novel type of Rydberg dimer, consisting of a Rydberg-state atom bound to a distant positive ion. The molecule is formed through long-range electric-multipole interaction between the Rydberg atom and the pointlike ion.

Floquet-tailored Rydberg interactions

Nature Communications, 2023
The Rydberg blockade is a key ingredient for entangling atoms in arrays. However, it requires atoms to be spaced well within the blockade radius, which limits the range of local quantum gates.

Spectroscopy of Rydberg states in erbium using electromagnetically induced transparency

Physical Review Research, 2021
We present a study of the Rydberg spectrum in ^{166}Er for series connected to the 4f^{12}(^{3}H_{6})6s, J_{c}=13/2, and J_{c}=11/2 ionic core states using an all-optical detection based on electromagnetically induced transparency in an effusive atomic ...

Composite spin approach to the blockade effect in Rydberg atom arrays

Physical Review Research, 2022
The Rydberg blockade induces strongly correlated many-body effects in Rydberg atom arrays, including rich ground-state phases and many-body scar states in the excitation spectrum.
