Theory of evaporative cooling with energy-dependent elastic scattering cross section and application to metastable helium
Paul J. J. Tol, W. Hogervorst, W. Vassen
The kinetic theory of evaporative cooling developed by Luiten et al. [Phys. Rev. A 53, 381 (1996)] is extended to include the dependence of the elastic scattering cross section on…
Nanolithography with metastable helium atoms in a high-power standing-wave light field
S. J. H. Petra, L. Feenstra, W. Hogervorst +1
We have created periodic nanoscale structures in a gold substrate with a lithography process using metastable triplet helium atoms that damage a hydrofobic resist layer on top of t…
Numerical simulations on the motion of atoms travelling through a standing-wave light field
S. J. H. Petra, K. A. H. van Leeuwen, L. Feenstra +2
The motion of metastable helium atoms travelling through a standing light wave is investigated with a semi-classical numerical model. The results of a calculation including the vel…
Effect of atomic transfer on the decay of a Bose-Einstein condensate
Pawel Zin, Andrzej Dragan, Szymon Charzynski +4
We present a model describing the decay of a Bose-Einstein condensate, which assumes the system to remain in thermal equilibrium during the decay. We show that under this assumptio…
