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…
Chiral quantum router with Rydberg atoms
Nikolaos E. Palaiodimopoulos, Simon Ohler, Michael Fleischhauer +1
We exploit controlled breaking of time-reversal symmetry to realize coherent routing of quantum information in spin networks. The key component of our scheme is a spin triangle who…
Griffiths Phase in a Facilitated Rydberg Gas at Low Temperature
Daniel Brady, Jana Bender, Patrick Mischke +3
The spread of excitations by Rydberg facilitation bears many similarities to epidemics. Such systems can be modeled with Monte-Carlo simulations of classical rate equations to grea…
Towards Learning Self-Organized Criticality of Rydberg Atoms using Graph Neural Networks
Simon Ohler, Daniel Brady, Winfried Lötzsch +2
Self-Organized Criticality (SOC) is a ubiquitous dynamical phenomenon believed to be responsible for the emergence of universal scale-invariant behavior in many, seemingly unrelate…
Learning the Solution Operator of Boundary Value Problems using Graph Neural Networks
Winfried Lötzsch, Simon Ohler, Johannes S. Otterbach
As an alternative to classical numerical solvers for partial differential equations (PDEs) subject to boundary value constraints, there has been a surge of interest in investigatin…
Quantum spin liquids of Rydberg excitations in a honeycomb lattice induced by density-dependent Peierls phases
Simon Ohler, Maximilian Kiefer-Emmanouilidis, Michael Fleischhauer
We show that the nonlinear transport of bosonic excitations in a two-dimensional honeycomb lattice of spin-orbit coupled Rydberg atoms gives rise to disordered quantum phases which…
Self-generated quantum gauge fields in arrays of Rydberg atoms
Simon Ohler, Maximilian Kiefer-Emmanouilidis, Antoine Browaeys +2
As shown in recent experiments [V. Lienhard et al., Phys. Rev. X 10, 021031 (2020)], spin-orbit coupling in systems of Rydberg atoms can give rise to density-dependent Peierls Phas…
