Topological bands in the continuum using Rydberg states
Sebastian Weber, Przemyslaw Bienias, Hans Peter Büchler
The quest to realize topological band structures in artificial matter is strongly focused on lattice systems, and only quantum Hall physics is known to appear naturally also in the…
Realization of a density-dependent Peierls phase in a synthetic, spin-orbit coupled Rydberg system
Vincent Lienhard, Pascal Scholl, Sebastian Weber +8
We experimentally realize a Peierls phase in the hopping amplitude of excitations carried by Rydberg atoms, and observe the resulting characteristic chiral motion in a minimal setu…
Influence of surface plasmon polaritons on laser energy absorption and structuring of surfaces
P. N. Terekhin, O. Benhayoun, S. T. Weber +3
The accurate calculation of laser energy absorption during femto- or picosecond laser pulse experiments is very important for the description of the formation of periodic surface s…
Experimental realization of a symmetry protected topological phase of interacting bosons with Rydberg atoms
Sylvain de Léséleuc, Vincent Lienhard, Pascal Scholl +6
The concept of topological phases is a powerful framework to characterize ground states of quantum many-body systems that goes beyond the paradigm of symmetry breaking. While a few…
Topologically protected edge states in small Rydberg systems
Sebastian Weber, Sylvain de Léséleuc, Vincent Lienhard +4
We propose a simple setup of Rydberg atoms in a honeycomb lattice which gives rise to topologically protected edge states. The proposal is based on the combination of dipolar excha…
