Arbitrary optical traps with spatial light modulators — •Marvin Holten, Puneet Murthy, André Wenz, Gerhard Zürn, and Selim Jochim — Physikalisches Institut, Im Neuenheimer Feld 226, 69120 Heidelberg

One of the main challenges of quantum simulation is engineering the Hamiltonian. A particularly interesting approach towards realizing this goal has been the use of ultracold quantum gases trapped in tailor-made optical potentials. In this poster we show how such potentials can be created by using a phase-modulating Spatial Light Modulator. We investigate numerical methods to address the difficult problem of finding the correct phase pattern to obtain a desired intensity distribution. Furthermore, we develop algorithms to measure and correct aberrations introduced by the experimental setup. We present results of intensity patterns created with light in an actual setup and discuss the implementation of these techniques in ultracold atom experiments.
