Beyond linear response spectroscopy of ultracold Fermi gases
J. Kinnunen, P. Torma
We study RF-spectroscopy of ultracold Fermi gas by going beyond the linear response in the field-matter interaction. Higher order perturbation theory allows virtual processes and e…

Effect of wavelength dependence of nonlinearity, gain, and dispersion in photonic crystal fiber amplifiers
A. Huttunen, P. Torma
Photonic crystal fibers are used in fiber amplifiers and lasers because of the flexibility in the design of mode area and dispersion. However, these quantities depend strongly on t…

Quasi two-dimensional superfluid Fermi gases
J. -P. Martikainen, Paivi Torma
We study a quasi two-dimensional superfluid Fermi gas where the confinement in the third direction is due to a strong harmonic trapping. We investigate the behavior of such a syste…
