Haldane phase in one-dimensional systems of Rydberg atoms — •Johannes Mögerle and Hans Peter Büchler — Institute for Theoretical Physics III and Center for Integrated Quantum Science and Technology, University of Stuttgart, 70550 Stuttgart, Germany

Quantum many body physics features a wide range of interesting phenomena. This includes new, so-called topological quantum phases, which appear due to entanglement. One of the earliest proposed such phase is the Haldane phase in a one-dimensional Spin 1 chain, which later was found to be a symmetry protected topological phase. A promising platform to realize all kinds of topological phases are Rydberg atoms with their strong and tunable interactions.

This work focuses on numerically simulating the Haldane phase in a parameter regime which is accessible in Rydberg systems. Moreover, we are proposing a concrete example of experimental parameters using a three level system in Rubidium atoms to realize a groundstate close to the famous AKLT state.
