Macroscopic superposition states in rotating ring lattices
Andreas Nunnenkamp, Ana Maria Rey
We investigate the effects of rotation on one-dimensional ultracold bosons confined to optical ring lattices. First, we show that there exists a critical rotation frequency at whic…
Generation of macroscopic superposition states in ring superlattices
Andreas Nunnenkamp, Ana Maria Rey, Keith Burnett
Ultracold bosons in rotating ring lattices have previously been shown to form macroscopic superpositions of different quasi-momentum states. We demonstrate that the generation of s…
Many-body protected entanglement generation in interacting spin systems
A. M. Rey, L. Jiang, M. Fleischhauer +2
We discuss a method to achieve decoherence resistent entanglement generation in two level spin systems governed by gapped and multi-degenerate Hamiltonians. In such systems, while…
Quantum limited measurements of atomic scattering properties
A. M. Rey, L. Jiang, M. D. Lukin
We propose a method to perform precision measurements of the interaction parameters in systems of N ultra-cold spin 1/2 atoms. The spectroscopy is realized by first creating a cohe…
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…
Bragg spectroscopy of trapped one dimensional strongly interacting bosons in optical lattices: Probing the cake-structure
Guido Pupillo, Ana Maria Rey, G. George Batrouni
We study Bragg spectroscopy of strongly interacting one dimensional bosons loaded in an optical lattice plus an additional parabolic potential. We calculate the dynamic structure f…
