Coherently delocalized states in dipole interacting Rydberg ensembles: the role of internal degeneracies
Ghassan Abumwis, Christopher W. Wächtler, Matthew T. Eiles +1
We investigate the effect of degenerate atomic states on the exciton delocalization of dipole-dipole interacting Rydberg assemblies. Using a frozen gas and regular one-, two-, and…
Delocalization in two and three-dimensional Rydberg gases
Ghassan Abumwis, Matthew T. Eiles, Alexander Eisfeld
As was recently shown in Ref. 1, many eigenstates of a random Rydberg gas with resonant dipole-dipole interactions are highly delocalized. Although the high degree of delocalizatio…
Extended coherently delocalized states in a frozen Rydberg gas
Ghassan Abumwis, Matthew T. Eiles, Alex Eisfeld
The long-range dipole-dipole interaction can create delocalized states due to the exchange of excitation between Rydberg atoms. We show that even in a random gas many of the single…
Transport on flexible Rydberg aggregates using circular states
M. M. Aliyu, A. Ulugöl, G. Abumwis +1
Assemblies of interacting Rydberg atoms show promise for the quantum simulation of transport phenomena, quantum chemistry and condensed matter systems. Such schemes are typically l…
Multi-Excitons in Flexible Rydberg Aggregates
Ghassan Abumwis, Sebastian Wüster
Flexible Rydberg aggregates, assemblies of few Rydberg atoms coherently sharing electronic excitations while undergoing directed atomic motion, show great promise as quantum simula…
