Parton Mean-Field Theory of a Rydberg Quantum Spin Liquid induced by Density-Dependent Peierls Phases
Benno Bock, Simon Ohler, Michael Fleischhauer
We derive a parton mean-field Hamiltonian for Rydberg excitations on a honeycomb lattice with nearest and density-dependent, complex next-nearest neighbor hopping. Numerical result…

Nonequilibrium Universality of Rydberg-Excitation Spreading on a Dynamic Network
Simon Ohler, Daniel Brady, Patrick Mischke +6
Understanding the universal properties of non-equilibrium phase transitions of spreading processes is a challenging problem. This applies in particular to irregular and dynamically…

Anomalous Directed Percolation on a Dynamic Network using Rydberg Facilitation
Daniel Brady, Simon Ohler, Johannes Otterbach +1
The facilitation of Rydberg excitations in a gas of atoms provides an ideal model system to study epidemic evolution on (dynamic) networks and self organization of complex systems…
