Effective Field Theory for Rydberg Polaritons

Author(s)
Michael Gullans, Yidan Wang, Jeff D. Thompson, Qiyu Liang, Vladan Vuletic, Mikhail D. Lukin, Alexey V. Gorshkov
We develop an effective field theory (EFT) to describe the few- and many-body propagation of one- dimensional Rydberg polaritons. We show that the photonic

Realizing Exactly Solvable SU(N) Magnets with Thermal Atoms

Author(s)
Michael Beverland, Gorjan Alagic, Michael Martin, Andrew Koller, Ana Maria Rey, Alexey V. Gorshkov
We show that n thermal fermionic alkaline-earth atoms in a flat-bottom trap allow one to robustly implement a spin model displaying two symmetries: the Sn

Anomalous broadening in driven dissipative Rydberg systems

Author(s)
Elizabeth A. Goldschmidt, Thomas L. Boulier, Roger C. Brown, Silvio B. Koller, Jeremy T. Young, Alexey V. Gorshkov, S L. Rolston, James V. Porto
We observe interaction-induced broadening of the two-photon 5s-18s transition in 87Rb atoms trapped in a 3D optical lattice. The measured linewidth increases by

Coulomb bound states of strongly interacting photons

Author(s)
Mohammad F. Maghrebi, Michael Gullans, Przemek Bienias, Soonwon Choi, Ivar Martin, Ofer Firstenberg, Mikhail D. Lukin, Hans Peter Buchler, Alexey V. Gorshkov
We show that two photons coupled to Rydberg states via electromagnetically induced transparency can interact via an effective Coulomb potential. This

Fractional Quantum Hall States of Rydberg Polaritons

Author(s)
Mohammad F. Maghrebi, Norman Y. Yao, Mohammad Hafezi, Thomas Pohl, Ofer Firstenberg, Alexey V. Gorshkov
We propose a scheme for realizing fractional quantum Hall states of light. In our scheme, photons of two polarizations are coupled to Rydberg atoms via

Kitaev chains with long-range interactions

Author(s)
Davide Vodola, Luca Lepori, Elisa Ercolessi, Alexey V. Gorshkov, Guido Pupillo
We propose and analyze a generalization of the Kitaev chain for fermions with long-range p-wave pairing, which decays with distance as a power-law with exponent

Persistence of locality in systems with power-law interactions

Author(s)
Zhexuan Gong, Michael S. Foss-Feig, Spyridon Michalakis, Alexey V. Gorshkov
Motivated by recent experiments with ultra-cold matter, we derive a new bound on the propagation of information in D- dimensional lattice models exhibiting 1/r

Non-local propagation of correlations in long-range interacting quantum systems

Author(s)
Phil Richerme, Zhexuan Gong, Aaron Lee, Crystal Senko, Jacob Smith, Michael S. Foss-Feig, Spyridon Michalakis, Alexey V. Gorshkov, Christopher Monroe
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
