Experimental implementation of laser cooling of trapped ions in strongly inhomogeneous magnetic fields

Physical Review Research, 2023
We demonstrate the Doppler laser cooling of ^{40}Ca^{+} ions confined in a segmented linear Paul trap in the presence of a strong quadrupolar magnetic field generated by two permanent ring magnets.

Laboratory Courses on Laser Spectroscopy and Atom Trapping

Atoms, 2020
We present an overview of experiments covered in two semester-length laboratory courses dedicated to laser spectroscopy and atom trapping. These courses constitute a powerful approach for teaching experimental physics in a manner that is both ...

Hypothermal opto-thermophoretic tweezers

Nature Communications, 2023
Optical tweezers have profound importance across fields ranging from manufacturing to biotechnology. However, the requirement of refractive index contrast and high laser power results in potential photon and thermal damage to the trapped objects, such as

Sub-Doppler Cooling and Compressed Trapping of YO Molecules at μK Temperatures

Physical Review X, 2020
Complex molecular structure demands customized solutions to laser cooling by extending its general set of principles and practices. Compared with other laser-cooled molecules, yttrium monoxide (YO) exhibits a large electron-nucleus interaction, resulting

Theory of an optical dipole trap for cold atoms [PDF]

, 2000
The theory of an atom dipole trap composed of a focused, far red-detuned, trapping laser beam, and a pair of red-detuned, counterpropagating, cooling beams is developed for the simplest realistic multilevel dipole interaction scheme based on a model of a

Search for a permanent EDM using laser cooled radioactive atom

EPJ Web of Conferences, 2014
The search for the electric-dipole moment (EDM) of laser-cooled francium (Fr) atoms could lead to a measurement for the electron EDM. It is predicted that the electron EDM would be enhanced by approximately three orders of magnitude in heavy atoms such ...

Instability Heating of Sympathetically-Cooled Ions in a Linear Paul Trap [PDF]

, 2002
Sympathetic laser cooling of ions stored within a linear-geometry, radio frequency, electric-quadrupole trap has been investigated using computational and theoretical techniques. The simulation, which allows 5 sample ions to interact with 35 laser-cooled
