Many-body correlations in one-dimensional optical lattices with alkaline-earth(-like) atoms

open access: yesScientific Reports, 2023
We explore the rich nature of correlations in the ground state of ultracold atoms trapped in state-dependent optical lattices. In particular, we consider interacting fermionic ytterbium or strontium atoms, realizing a two-orbital Hubbard model with two ...

Atomic masses of strontium and ytterbium

open access: yesPhysical Review A, 2012
The atomic masses of the three most abundant isotopes of strontium, ${}^{86,87,88}$Sr, and of the six most abundant isotopes of ytterbium, ${}^{170,171,172,173,174,176}$Yb, have been obtained from measurements of cyclotron frequency ratios of pairs of ions simultaneously trapped in a Penning trap.

Experimental Observation of the Suppression of the Dephasing in a Floquet Engineering Optical Lattice Clock

open access: yesApplied Sciences, 2022
Accurately manipulating quantum states is a fundamental strategy for improving the performance of quantum metrology, computing, and simulation. However, the quantum state is susceptible to dephasing due to the temperature and density of the atomic ...

An Evaluation of the Zeeman Shift of the 87Sr Optical Lattice Clock at the National Time Service Center

open access: yesApplied Sciences, 2020
The Zeeman shift plays an important role in the evaluation of optical lattice clocks since a strong bias magnetic field is applied for departing Zeeman sublevels and defining a quantization axis.

Optical magnetism and wavefront control by arrays of strontium atoms

open access: yesPhysical Review Research, 2022
By analyzing the parameters of electronic transitions, we show how bosonic Sr atoms in planar optical lattices can be engineered to exhibit optical magnetism and other higher-order electromagnetic multipoles that can be harnessed for wavefront control of

Effect of ionic substitutions on the magnetic properties of strontium hexaferrite: A first principles study

open access: yesAIP Advances, 2017
We investigated the effect of substitution of various ions at the Fe sites on magnetic properties of strontium hexaferrite (SrFe12O19) using first principles method based on density functional theory.

Narrow-line imaging of single strontium atoms in shallow optical tweezers

open access: yesPhysical Review Research, 2022
Single strontium atoms held in optical tweezers have so far only been imaged using the broad ^{1}S_{0}-^{1}P_{1}transition. For Yb, use of the narrow (183-kHz wide) ^{1}S_{0}-^{3}P_{1}transition for simultaneous imaging and cooling has been demonstrated ...

Injection locking of a low cost high power laser diode at 461 nm [PDF]

open access: yes, 2016
Stable laser sources at 461 nm are important for optical cooling of strontium atoms. In most existing experiments this wavelength is obtained by frequency doubling infrared lasers, since blue laser diodes either have low power or large emission ...
