Tailor-made optical potentials with Spatial Light Modulators — •Antonia Klein, Marvin Holten, Luca Bayha, Puneet Murthy, Philipp Preiß, Gerhard Zuern, and Selim Jochim — Physikalisches Institut, University of Heidelberg, Germany

Initializing a system in a desired low entropy state is one of the main challenges of quantum simulation employing ultracold atoms. In most experiments a bulk gas is evaporatively cooled down and loaded into the desired potential.

On this poster we present our new setup following a different bottom-up approach. The idea is to assemble a complicated potential out of many separately prepared building blocks, which can be initialized with very low initial entropy. The required tailor made potentials are created by using a phase modulating Spatial Light Modulator implemented in our group's 2D lithium experiment.

We show first measurements performed with the extended setup. Starting with the simple building block of a double well, we explore the feasibility of several lattice geometries. We also investigate the possibility to study 1D physics with the long term goal of creating topological edge states.
