TL;DR
This paper proposes using photonic crystal structures to create subwavelength optical lattices and induce strong, long-range atom-atom interactions for quantum simulation with ultracold atoms.
Contribution
It introduces a novel scheme combining Guided Modes and Casimir-Polder forces in photonic crystals to engineer subwavelength lattices and atom interactions.
Findings
Guided Modes enable large, long-range interactions between atoms.
The scheme allows for the implementation of spin models for quantum simulation.
Potential for creating highly controllable quantum many-body systems.
Abstract
We propose the use of photonic crystal structures to design subwavelength optical lattices in two dimensions for ultracold atoms by using both Guided Modes and Casimir-Polder forces. We further show how to use Guided Modes for photon-induced large and strongly long-range interactions between trapped atoms. Finally, we analyze the prospects of this scheme to implement spin models for quantum simulation
