Surface Chemical Trapping of Optical Cycling Centers [PDF]
Physical Chemistry Chemical Physics, 2020 Quantum information processors based on trapped atoms utilize laser-induced optical cycling transitions for state preparation and measurement. These transitions consist of an electronic excitation from the ground to an excited state and a decay back to the initial ground state, associated with a photon emission.

Spin-Mechanics with Nitrogen-Vacancy Centers and Trapped Particles [PDF]
Micromachines, 2021 Controlling the motion of macroscopic oscillators in the quantum regime has been the subject of intense research in recent decades. In this direction, opto-mechanical systems, where the motion of micro-objects is strongly coupled with laser light radiation pressure, have had tremendous success.

On the Motion of Trapped Particles in the Vicinity of Corotation Centers [PDF]
International Astronomical Union Colloquium, 1999 AbstractIn the present paper we analyse the motion of a massless particle during the capture process in an exterior mean-motion resonance under the effects of an external dissipative force. In particular, we study the orbital evolution from its initial approach to the commensurability up to the final nesting place in the periodic orbit around the ...

Is Child-Centered Tobacco Prevention a Trap?
American Journal of Public Health, 2003 “There is no question that demands more public attention . . . than the prevailing methods of cigarette manufacturers to foster and stimulate smoking among children,” an angry New Yorker said in 1888. Tobacco manufacturers seduced the young with promotional prizes like pocket knives and lithograph albums, he said. “At the office of a leading factory in

Magic-wavelength optical traps for Rydberg atoms [PDF]
Phys. Rev. A 84, 043408 (2011), 2011 We propose blue-detuned optical traps that are suitable for trapping of both ground state and Rydberg excited atoms. Addition of a background compensation field or suitable choice of the trap geometry provides a magic trapping condition for ground and Rydberg atoms at the trap center.

Light effect in photoionization of traps in GaN MESFETs [PDF]
Pap. Phys. 1, 010006 (2009) [PIP Editor's Note: Also published in
the JEST, vol. 8, no. 1, pags. 51-54 (2010) in breach of the authors'
CreativeCommons License agreement with Papers in Physics.], 2009 Trapping of hot electron behavior by trap centers located in buffer layer of a wurtzite phase GaN MESFET has been simulated using an ensemble Monte Carlo simulation. The results of the simulation show that the trap centers are responsible for current collapse in GaN MESFET at low temperatures.

Performance Bounds of Magnetic Traps for Neutral Particles [PDF]
, 2022 Knowledge of the fundamental limitations on a magnetic trap for neutral particles is of paramount interest to designers as it allows for the rapid assessment of the feasibility of specific trap requirements or the quality of a given design. In this paper, performance limitations are defined for convexity of magnetic trapping potential and bias field ...

Cold hybrid electrical-optical ion trap [PDF]
arXiv, 2023 Advances in research such as quantum information and quantum chemistry require subtle methods for trapping particles (including ions, neutral atoms, molecules, etc.). Here we propose a hybrid ion trapping method by combining a Paul trap with optical tweezers.

Trapped-Electron Runaway Effect [PDF]
J. Plasma Phys. 81 (2015) 475810403, 2015 In a tokamak, trapped electrons subject to a strong electric field cannot run away immediately, because their parallel velocity does not increase over a bounce period. However, they do pinch towards the tokamak center. As they pinch towards the center, the trapping cone becomes more narrow, so eventually they can be detrapped and run away.

Electron spin resonance from NV centers in diamonds levitating in an ion trap [PDF]
New J. Phys. 19, 033031 (2017), 2016 We report observations of the Electron Spin Resonance (ESR) of Nitrogen Vacancy (NV) centers in diamonds that are levitating in an ion trap. Using a needle Paul trap operating under ambient conditions, we demonstrate efficient microwave driving of the electronic spin and show that the spin properties of deposited diamond particles measured by the ESR ...
