Quasienergy spectrum of complex atoms (2008)
Journal Article
Meṣe, E., & Potvliege, R. (2008). Quasienergy spectrum of complex atoms. Physical Review A, 77(2), Article 023414. https://doi.org/10.1103/physreva.77.023414

Representative sections of the quasienergy spectrum of argon and of alkali-metal atoms are presented for wavelengths between 250 nm and 800 nm and excursion amplitudes up to α0=20 a.u. The variation of the quasienergy spectrum with the wavelength of... Read More about Quasienergy spectrum of complex atoms.

The quasienergy spectrum of argon from 400 to 800 nm (2007)
Journal Article
Mese, E., & Potvliege, R. (2007). The quasienergy spectrum of argon from 400 to 800 nm. Laser Physics Letters, 4(5), 357-362

The Floquet quasienergy spectrum of argon atoms exposed to a strong laser field is presented for incident wavelengths of 400, 600, and 800 nm and electron excursion amplitudes up to 30 a.u. The calculation is performed by diagonalizing the Floquet Ha... Read More about The quasienergy spectrum of argon from 400 to 800 nm.

High-order above-threshold ionization of argon: plateau resonances and the Floquet quasienergy spectrum (2006)
Journal Article
Potvliege, R., & Vucic, S. (2006). High-order above-threshold ionization of argon: plateau resonances and the Floquet quasienergy spectrum. Physical Review A, 74(2), https://doi.org/10.1103/physreva.74.023412

The Floquet quasienergy spectrum of argon in a strong laser field of 800 nm wavelength is calculated for intensities up to 7×1013 W cm–2, and beyond for some states, using a discrete complex basis set. Many of the dressed excited states of interest s... Read More about High-order above-threshold ionization of argon: plateau resonances and the Floquet quasienergy spectrum.

Spatially selective loading of an optical lattice by light-shift engineering using an auxiliary laser field (2006)
Journal Article
Griffin, P., Weatherill, K., MacLeod, S., Potvliege, R., & Adams, C. (2006). Spatially selective loading of an optical lattice by light-shift engineering using an auxiliary laser field. New Journal of Physics, 8(11), https://doi.org/10.1088/1367-2630/8/1/011

I had the idea a long time ago that shifting the excited state energy level using an additional laser could be a useful tool in cold atoms experiments. In this paper we demonstrated experimentally the application of this idea to loading specific site...

Loading of selected sites in an optical lattice using light-shift engineering (2005)
Presentation / Conference Contribution
Griffin, P., Weatherill, K., Macleod, S., Potvliege, R., & Adams, C. (2005, June). Loading of selected sites in an optical lattice using light-shift engineering. Presented at International Conference of Laser Spectroscopy, Aviemore

We report on a method of light–shift engineering where an additional laser is used to tune the energy of an excited atomic state. We show that the technique can be used to enhance the loading of a deep optical lattice or selectively load specific sit...
