Negative Refraction of Excitations in the Bose-Hubbard Model
R. A. Henry, J. Q. Quach, C-H. Su +2
Ultracold atoms in optical lattices provide a unique opportunity to study Bose- Hubbard physics. In this work we show that by considering a spatially varying onsite interaction it…
Transformation optics for cavity array metamaterials
James Q. Quach, Chun-Hsu Su, Andrew D. Greentree
Cavity array metamaterials (CAMs), composed of optical microcavities in a lattice coupled via tight-binding interactions, represent a novel architecture for engineering metamateria…
Domain structures in quantum graphity
James Q. Quach, Chun-Hsu Su, Andrew M. Martin +1
Quantum graphity offers the intriguing notion that space emerges in the low energy states of the spatial degrees of freedom of a dynamical lattice. Here we investigate metastable d…
Coupling slot-waveguide cavities for large-scale quantum optical devices
Chun-Hsu Su, Mark P. Hiscocks, Brant C. Gibson +3
By offering effective modal volumes significantly less than a cubic wavelength, slot-waveguide cavities offer a new in-road into strong atom-photon coupling in the visible regime.…
Reconfigurable quantum metamaterials
James Q. Quach, Chun-Hsu Su, Andrew M. Martin +2
By coupling controllable quantum systems into larger structures we introduce the concept of a quantum metamaterial. Conventional meta-materials represent one of the most important…
Tunable photon-assisted bleaching of three-level systems for noise filtration
Chun-Hsu Su, Andrew D. Greentree, Raymond G. Beausoleil +4
Electromagnetically-induced transparency (EIT) exploits quantum coherence to burn subnatural linewidth holes within a spectral line. We investigate the less explored properties of…
