Tunable atom-trapping based on a plasmonic chiral metamaterial

Nanophotonics, 2019
Chiral metamaterials provide a very convenient way to actively regulate the light field via external means, which is very important in nanophotonics.

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 ...

Magnetic-film atom chip with 10 $\mu$m period lattices of microtraps for quantum information science with Rydberg atoms [PDF]

, 2014
We describe the fabrication and construction of a setup for creating lattices of magnetic microtraps for ultracold atoms on an atom chip. The lattice is defined by lithographic patterning of a permanent magnetic film.

Dense atom clouds in a holographic atom trap [PDF]

Optics Letters, 2003
We demonstrate the production of high density cold atom samples (2e14 atoms/cc) in a simple optical lattice formed with YAG light that is diffracted from a holographic phase plate. A loading protocol is described that results in 10,000 atoms per lattice site. Rapid free evaporation leads to phase space densities of 1/150 within 50 msec.

Tracking Evaporative Cooling of a Mesoscopic Atomic Quantum Gas in Real Time

Physical Review X, 2021
The fluctuations in thermodynamic and transport properties in many-body systems gain importance as the number of constituent particles is reduced. Ultracold atomic gases provide a clean setting for the study of mesoscopic systems; however, the detection ...

Magneto-Optical Traps for Cold Atomic Gravimetry: Research Status and Development Trends

Applied Sciences, 2023
The cold atomic gravimeter (CAG) has the advantage of high measurement accuracy and does not need to be calibrated on a regular basis. To achieve cold atom interference, it is first necessary to cool and trap the atoms by magneto-optical trap (MOT ...

Cooling of a single atom in an optical trap inside a resonator [PDF]

, 2001
We present detailed discussions of cooling and trapping mechanisms for an atom in an optical trap inside an optical cavity, as relevant to recent experiments.

Collective Two-Atom Effects and Trapping States in the Micromaser [PDF]

, 2006
We investigate signals of trapping states in the micromaser system in terms of the average number of cavity photons as well as a suitably defined correlation length of atoms leaving the cavity.
