Zitterbewegung in the honeycomb lattice — •Michael Hauber1, Benjamin Deissler2, Johannes Hecker Denschlag2, and Alejandro Muramatsu1 — 1Institut für Theoretische Physik III, Universität Stuttgart — 2Institut für Quantenmaterie, Universität Ulm
We present simulations of the dynamics of relativistic fermions on a honeycomb lattice to investigate the Zitterbewegung in 2+1 dimensions under real conditions, such as finite lattice size and external potentials. Our results serve as a guide for an experimental realization of such systems with ultracold fermionic atoms (6 Li) on an optical lattice. From our simulations, Zitterbewegung should be observable in such a system with site-resolved imaging capabilities.
