Fractional Quantum Hall States of Rydberg Polaritons
Mohammad F. Maghrebi, Norman Y. Yao, Mohammad Hafezi +3
We propose a scheme for realizing fractional quantum Hall states of light. In our scheme, photons of two polarizations are coupled to different atomic Rydberg states to form two fl…
Nearly-linear light cones in long-range interacting quantum systems
Michael Foss-Feig, Zhe-Xuan Gong, Charles W. Clark +1
In non-relativistic quantum theories with short-range Hamiltonians, a velocity can be chosen such that the influence of any local perturbation is approximately confined to with…
Realizing Exactly Solvable SU(N) Magnets with Thermal Atoms
Michael E. Beverland, Gorjan Alagic, Michael J. Martin +3
We show that thermal fermionic alkaline-earth atoms in a flat-bottom trap allow one to robustly implement a spin model displaying two symmetries: the symmetry that permut…
Kitaev chains with long-range pairing
Davide Vodola, Luca Lepori, Elisa Ercolessi +2
We propose and analyze a generalization of the Kitaev chain for fermions with long-range -wave pairing, which decays with distance as a power-law with exponent . Using the in…
Non-local propagation of correlations in long-range interacting quantum systems
Philip Richerme, Zhe-Xuan Gong, Aaron Lee +6
The maximum speed with which information can propagate in a quantum many-body system directly affects how quickly disparate parts of the system can become correlated and how diffic…
Persistence of locality in systems with power-law interactions
Zhe-Xuan Gong, Michael Foss-Feig, Spyridon Michalakis +1
Motivated by recent experiments with ultra-cold matter, we derive a new bound on the propagation of information in -dimensional lattice models exhibiting interactions wi…
