Multiple scattering dynamics of fermions at an isolated p-wave resonance

Autor: Thomas, Ryan, Roberts, Kris O., Tiesinga, Eite, Wade, Andrew C. J., Blakie, P. Blair, Deb, Amita B., Kjærgaard, Niels

Publikováno v: Nature Communications 7, 12069 (2016)

The wavefunction for indistinguishable fermions is anti-symmetric under particle exchange, which directly leads to the Pauli exclusion principle, and hence underlies the structure of atoms and the properties of almost all materials. In the dynamics o

Steerable optical tweezers for ultracold atom studies

Autor: Roberts, Kris O., McKellar, Thomas, Fekete, Julia, Rakonjac, Ana, Deb, Amita B., Kjærgaard, Niels

Publikováno v: Optics Letters, Vol. 39, Issue 7, pp. 2012-2015 (2014)

We report on the implementation of an optical tweezer system for controlled transport of ultracold atoms along a narrow, static confinement channel. The tweezer system is based on high-efficiency acousto-optical deflectors and offers two-dimensional

Note: Computer controlled rotation mount for large diameter optics

Autor: Rakonjac, Ana, Roberts, Kris O., Deb, Amita B., Kjærgaard, Niels

Publikováno v: Review of Scientific Instruments {\bf 84} 026107 (2013)

We describe the construction of a motorized optical rotation mount with a 40 mm clear aperture. The device is used to remotely control the power of large diameter laser beams for a magneto-optical trap (MOT). A piezo-electric ultrasonic motor on a pr
