Anyonic interferometry and protected memories in atomic spin lattices
Liang Jiang, Gavin K. Brennen, Alexey V. Gorshkov +5
Strongly correlated quantum systems can exhibit exotic behavior called topological order which is characterized by non-local correlations that depend on the system topology. Such s…
Quantum Spin Dynamics of Mode-Squeezed Luttinger Liquids in Two-Component Atomic Gases
Artur Widera, Stefan Trotzky, Patrick Cheinet +6
We report on the observation of the phase dynamics of interacting one-dimensional ultracold bosonic gases with two internal degrees of freedom. By controlling the non-linear atomic…
Fractional Quantum Hall Effect in Optical Lattices
Mohammad Hafezi, Anders S. Sorensen, Eugene Demler +1
We analyze a recently proposed method to create fractional quantum Hall (FQH) states of atoms confined in optical lattices [A. Sørensen {\it et al.}, Phys. Rev. Lett. {\bf 94} 0868…
Characterization of topological states on a lattice with Chern number
Mohammad Hafezi, Anders S. Sorensen, Mikhail D. Lukin +1
We study Chern numbers to characterize the ground state of strongly interacting systems on a lattice. This method allows us to perform a numerical characterization of bosonic fract…
Fundamental noise in matter interferometers
Adilet Imambekov, Vladimir Gritsev, Eugene Demler
These lecture notes discuss two effects which contribute to the reduction of the interference fringe contrast in matter interferometers. The first effect is the shot noise arising…
Noise-resistant entanglement of strongly interacting spin systems
A. M. Rey, L. Jiang, M. Fleischhauer +2
We propose and analyze a scheme that makes use of interactions between spins to protect certain correlated many-body states from decoherence. The method exploits the finite energy…
