Dark state optical lattice with sub-wavelength spatial structure

February 20, 2018

Sarthak Subhankar, Tsz-Chun Tsui, James V. Porto, Steve Rolston, Przemek Bienias, Alexey Gorshkov, Mateusz Lacki, Michael Baranov, Peter Zoller
We report on the experimental realization of a conservative optical lattice for cold atoms with sub-wavelength spatial structure. The potential is based on the nonlinear optical response of three- level atoms in laser-dressed dark states, which is not

Efimov States of Strongly Interacting Photons

Jacob M. Taylor, Alexey V. Gorshkov, Michael Gullans, D Ruzik, Seth Rittenhouse, J.P. D'Incao, Paul Julienne, S Diehl
We introduce a new system to study Efimov physics based on interacting photons in cold gases of Rydberg atoms. This system has a large anisotropy between the longitudinal mass of the photons, arising from dispersion, and the transverse mass of the photons

Spontaneous avalanche dephasing in large Rydberg ensembles

Thomas L. Boulier, Eric Magnan, Carlos Bracamontes, James Maslek, Elizabeth Goldschmidt, Jeremey Young, Alexey Gorshkov, Steven Rolston, James V. Porto
Strong dipole-exchange interactions due to spontaneously produced contaminant states can trigger rapid dephasing in many-body Rydberg ensembles [E. Goldschmidt et al., PRL 116, 113001 (2016)]. Such broadening has serious implications for many proposals to

Effective Field Theory for Rydberg Polaritons

September 9, 2016

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 transmission through the Rydberg medium can be found by mapping the propagation problem to a
