Controlled manipulation of light by cooperative response of atoms in an optical lattice

SD Jenkins, J Ruostekoski - Physical Review A—Atomic, Molecular, and …, 2012 - APS
We show that atoms in an optical lattice can respond cooperatively to resonant incident light
and that such a response can be employed for precise control and manipulation of light on a …

Spin-orbit coupling and topological phases for ultracold atoms

L Zhang, XJ Liu - Synthetic Spin-Orbit Coupling in Cold Atoms, 2018 - World Scientific
Cold atoms with laser-induced spin-orbit (SO) interactions provide promising platforms to
explore novel quantum physics, in particular the exotic topological phases, beyond natural …

Single-site-resolved measurement of the current statistics in optical lattices

S Keßler, F Marquardt - Physical Review A, 2014 - APS
At present, great effort is spent on the experimental realization of gauge fields for quantum

Characterization of quasiholes in fractional Chern insulators

Z Liu, RN Bhatt, N Regnault - Physical Review B, 2015 - APS
We provide a detailed study of the Abelian quasiholes of ν= 1/2 bosonic fractional quantum
Hall states on the torus geometry and in fractional Chern insulators. We find that the density …

Characterization of quasiholes in two-component fractional quantum Hall states and fractional Chern insulators in =2 flat bands

We consider the effect of contact interaction in a prototypical quantum spin Hall system of
pseudo-spin-1/2 particles. A strong effective magnetic field with opposite directions for the …

Matter-wave scattering from strongly interacting bosons in an optical lattice
