Atom lithography with two-dimensional optical masks
S. J. H. Petra, K. A. H. van Leeuwen, L. Feenstra +2
With a two-dimensional (2D) optical mask, nanoscale patterns are created for the first time in an atom lithography process using metastable helium atoms. The internal energy of the…
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…
Microtraps and Atom Chips: Toolboxes for Cold Atom Physics
L. Feenstra, L. M. Andersson, J. Schmiedmayer
Magnetic microtraps and Atom Chips are safe, small-scale, reliable and flexible tools to prepare ultra-cold and degenerate atom clouds as sources for various atom-optical experimen…
Bose-Einstein Condensation in a simple Microtrap
S. Schneider, A. Kasper, Ch. vom Hagen +7
A Bose-Einstein condensate is created in a simple and robust miniature Ioffe-Pritchard trap, the so-called Z trap. This trap follows from the mere combination of a Z-shaped current…
