Divalent Rydberg atoms in optical lattices: Intensity landscape and magic trapping

  title={Divalent Rydberg atoms in optical lattices: Intensity landscape and magic trapping},
  author={Turker Topcu and Andrei Derevianko},
  journal={Physical Review A},
We develop a theoretical understanding of the trapping of divalent Rydberg atoms in optical lattices. Because the size of the Rydberg electron cloud can be comparable to the scale of spatial variations of laser intensity, we pay special attention to averaging optical fields over the atomic wave functions. The optical potential is proportional to the ac Stark polarizability. We find that in the independent-particle approximation for the valence electrons, this polarizability breaks into two…

Possibility of triple magic trapping of clock and Rydberg states of divalent atoms in optical lattices

We predict the possibility of ‘triply magic’ optical lattice trapping of neutral divalent atoms. In such a lattice, the 1 ⁢ S 0 and 3 P 0 clock states and an additional Rydberg state experience

Theory of long-range interactions for Rydberg states attached to hyperfine-split cores

The theory is developed for one and two atom interactions when the atom has a Rydberg electron attached to a hyperfine split core state. This situation is relevant for some of the rare earth and

Multichannel quantum defect theory of strontium bound Rydberg states

Using the reactance matrix approach, we systematically develop new multichannel quantum defect theory (MQDT) models for the singlet and triplet S, P, D and F states of strontium below the first

Trapping Yb171 atoms into a one-dimensional optical lattice with a small waist

In most experiments with atoms trapped in optical lattices, the transverse size of the optical lattice beams is of the order of tens of micrometers, and loading many atoms into smaller optical

Quantum Computing with Circular Rydberg Atoms

Rydberg atom arrays are a leading platform for quantum computing and simulation, combining strong interactions with highly coherent operations and flexible geometries. However, the achievable

Trapping of Rydberg atoms in tight magnetic microtraps

We explore the possibility to trap Rydberg atoms in tightly confining magnetic microtraps. The trapping frequencies for Rydberg atoms are expected to be influenced strongly by magnetic-field

High-dimensional SO(4)-symmetric Rydberg manifolds for quantum simulation

We develop a toolbox for manipulating arrays of Rydberg atoms prepared in high-dimensional hydrogen-like manifolds in the regime of linear Stark and Zeeman effect. We exploit the SO(4) symmetry to

A method for calculating the properties of Rydberg states and Rydberg–Rydberg interaction between two 87Sr atoms is described. The method is based on a multichannel quantum defect theory description

Theoretical Analysis of Wave Function under the Influence of Harmonic Oscillator Potential in BEC Experiments

This paper will focus on theoretical study of BEC in one dimension with weakly attractive interactions in particular in a symmetric harmonic oscillator potential. In this case, the ground state may

Correlation between the magic wavelengths and the polarization direction of the linearly polarized laser in the Ca+ optical clock

The magic wavelengths for different Zeeman components are measured based on the Ca-40(+) optical clock. The dynamic dipole polarizability of a non-zero angular moment level has correlation with the



A cold strontium Rydberg gas

Cold gases of Rydberg atoms are an ideal system in which to study the novel effects of strong interatomic interactions. This thesis describes the design and construction of the world's first
