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.

Observation of second- and higher-order electric quadrupole interactions with an atomic ion
Physical Review Research, 2021 We observe an atomic ion's response to an electric quadrupole field to second and higher orders; this arises from the ion's electric quadrupole polarizability and hyperpolarizabilities.

Molecular Physics, 2005 This paper discusses the nature of heavy Rydberg states, i.e. quantum states in molecular systems that are bound by the almost pure Coulomb potential between pairs of ions. A theoretical framework is developed in terms of mass-scaling laws for heavy Rydberg systems of certain reduced mass, so that the physics of electronic Rydberg states can be ...

Single-color two-photon spectroscopy of Rydberg states in electric fields [PDF]
, 2014 Rydberg states of atomic helium with principal quantum numbers ranging from n=20 to n=100 have been prepared by non-resonance-enhanced single-color two-photon excitation from the metastable 2 {^3}S{_1} state.

New Journal of Physics, 2023 We present a method for measuring the polarizability of Rydberg ions confined in the harmonic potential of a Paul trap. For a highly excited electronic state, the coupling between the electronic wave function and the trapping field modifies the ...

Dynamical Crystallization in the Dipole Blockade of Ultracold Atoms [PDF]
, 2009 We describe a method for controlling many-body states in extended ensembles of Rydberg atoms, forming crystalline structures during laser excitation of a frozen atomic gas. Specifically, we predict the existence of an excitation number staircase in laser

Creation of Rydberg Polarons in a Bose Gas [PDF]
, 2018 We report spectroscopic observation of Rydberg polarons in an atomic Bose gas. Polarons are created by excitation of Rydberg atoms as impurities in a strontium Bose-Einstein condensate.
