Simulating neural network criticality and resource dynamics with Rydberg gases
Patrick Mischke, Herwig Ott, Michael Fleischhauer +1
Efficient operation of neural networks has been linked to criticality in their underlying non-equilibrium excitation dynamics. However, obtaining experimental evidence of this conj…
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…
Dephasing in Rydberg Facilitation Due to State-Dependent Dipole Forces
Tom Schlegel, Evangelia Konstantinidou, Michael Fleischhauer +1
Rydberg atoms allow for the experimental study of open many-body systems and nonequilibrium phenomena. High dephasing rates are a generic feature of these systems, and therefore th…
Quantum-Noise Induced Localization and Motional Squeezing in a Rydberg Quantum Simulator
Daniel Brady, Benno Bock, Michael Fleischhauer
We investigate the interplay between mechanical forces and the internal-state dynamics of Rydberg excitations in atom-tweezer arrays. Dipole interactions between Rydberg atoms faci…
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…
Impurities in a trapped 1D Bose gas of arbitrary interaction strength: localization-delocalization transition and absence of self-localization
Dennis Breu, Eric Vidal Marcos, Martin Will +1
We discuss impurities in a one-dimensional Bose gas with arbitrary boson-boson and boson-impurity interactions. To fully account for quantum effects, we employ numerical simulation…
