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

AIP 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.

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

Applied 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

Physical 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

Structure and properties of strontium-doped phosphate-based glasses [PDF]

, 2008
Owing to similarity in both ionic size and polarity, strontium (Sr2+) is known to behave in a comparable way to calcium (Ca2+), and its role in bone metabolism has been well documented as both anti-resorptive and bone forming.

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

Physical 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 ...

Alternative techniques for the production and manipulation of ultracold atoms [PDF]

, 2012
This Thesis contains details of the construction and characterisation of a compact apparatus for the cooling of ultracold atoms to quantum degeneracy, and their manipulation in flexible holographic optical traps. We have designed and built two iterations

Non-Abelian adiabatic geometric transformations in a cold strontium gas

Nature Communications, 2018
The symmetry group and geometric phase of a system are responsible for many quantum properties related to non-trivial topology. Here the authors show non-Abelian geometric phase in laser-coupled ultracold strontium atoms by using a tripod scheme.

Trapping and cooling of strontium atoms in 532 nm optical tweezers

SciPost Physics Core
We demonstrate deterministic preparation, cooling, and fluorescence detection of individual strontium-88 atoms trapped in optical tweezers. We compare trapping, cooling and imaging in the established wavelength of 813 nm and the technically more ...

A cold strontium Rydberg gas [PDF]

, 2011
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 experiment to study Rydberg states in a cold gas of an alkaline
