Towards quantum simulations in a triangular surface trap — •Manuel Mielenz, Henning Kalis, Ulrich Warring, and Tobias Schaetz — Physikalisches Institut, Albert-Ludwigs Universität Freiburg

Laser-cooled ions, trapped in a Paul Trap have proven to be an ideal system for quantum simulations [1]. While various experiments with a small number of ions have been demonstrated, scaling to large systems still poses a major challange. A promising approach to overcome this limition, is to use surface traps, whose electrode lies entirely in a plane [2]. Optimized electrodes allow to trap ions in an arbitrary pattern with each ion in an indiviual potential well [3], allowing for instance the simulation of extended lattices of spins or charged particles in a gauge field [4]. Our group, in collaboration with Sandia National Labs, recently demonstrated trapping ions in a novel kind of surface trap. Here, three ions are triangularly arranged in separated wells, still being close enough ( 40 µm ) to exhibit sufficient interaction to allow for simulations of simple two-dimensional quantum systems. In my talk, first results will be presented.
