P3.00001: Atom by atom control of light and matter using neutral atom arrays Invited Speaker: mikhail lukin We will describe our efforts to create a scalable quantum many-body system assembled atom by atom. Our approach makes use of deterministically prepared regular arrays of individually controlled, ultra cold neutral atoms loaded in dipole traps. Techniques to engineer interactions between the trapped atoms using optical photons, nanophotonic devices and Rydberg excitations will be described. [Preview Abstract] |

P3.00002: Hybrid atom-nanophotonic lattices for quantum optics and many-body physics Invited Speaker: Chen-Lung Hung Interfacing light with cold atoms localized near photonic crystal cavities and waveguides presents new opportunities for realizing scalable quantum networks and novel quantum phases of light and matter. Such hybrid system could bring together excellent mobility of photons, and quantum non-linearity as well as control toolbox available for cold atoms in a highly engineered setting. In this talk, I will discuss recent experimental progress toward achieving strong atom-atom interactions in a nanophotonic lattice for light, and theory prospects for inducing long-range quantum dynamics for quantum network and many-body physics.

P3.00003: Nonlinear optomechanics with graphene Airlia Shaffer, Yogesh Sharad Patil, Hil F. H. Cheung, Ke Wang, Mukund Vengalattore To date, studies of cavity optomechanics have been limited to exploiting the linear interactions between the light and mechanics. However, investigations of quantum signal transduction, quantum enhanced metrology and manybody physics with optomechanics each require strong, nonlinear interactions. Graphene nanomembranes are an exciting prospect for realizing such studies due to their inherently nonlinear nature and low mass. We fabricate large graphene nanomembranes and study their mechanical and optical properties. By using dark ground imaging techniques, we correlate their eigenmode shapes with the measured dissipation. We study their hysteretic response present even at low driving amplitudes, and their nonlinear dissipation. Finally, we discuss ongoing efforts to use these resonators for studies of quantum optomechanics and force sensing. [Preview Abstract] |

P3.00004: Applications of the Lithium Focused Ion Beam: Nanoscale Electrochemistry and Microdisk Mode Imaging William McGehee, Saya Takeuchi, Thomas Michels, Vladimir Oleshko, Vladimir Aksyuk, Christopher Soles, Jabez McClelland The NIST-developed lithium Focused-Ion-Beam (LiFIB) system creates a low-energy, picoampere-scale ion beam from a photoionized gas of laser-cooled atoms. The ion beam can be focused to a <30 nm spot and scanned across a sample. This enables imaging through collection of ion-induced secondary electrons (similar to SEM) as well as the ability to selectively deposit lithium-ions into nanoscale volumes in a material. We exploit this second ability of the LiFIB to selectively "titrate" lithium ions as a means of probing the optical modes in microdisk resonators as well as for exploring nanoscale, Li-ion electrochemistry in battery-relevant materials. We present an overview of both measurements, including imaging of the optical mode in a silicon microdisk and a comparison of FIB and electrochemical lithiation of tin. [Preview Abstract] |

P3.00005: Nanoscale manipulation of light using topological plasmonic crystals Chenxu Liu, M. V. Gurudev Dutt, David Pekker Robust manipulation of light at the nanoscale is an outstanding problem in photonics and quantum optics. Here we propose a topologically inspired solution to this problem. We analyzed a plasmonic crystal composed of an array of parallel nanowires with unequal spacing. In the paraxial approximation, the Helmholtz equation that describes the propagation of light along the nanowires maps onto the Schrödinger equation of the Su-Schrieffer-Heeger (SSH) model. We designed a new type of plasmonic crystal structures which can be used to guide, focus and manipulate light using topological defect modes (i.e. domain walls in the plasmonic crystal). The proposed structures could be useful in coupling free-space optics to quantum emitters such as atoms or color centers. [Preview Abstract] |

P3.00006: Control of multiple excited Rydberg states around segmented carbon nanotubes Peter Schmelcher, Hossein Sadeghpour, Johannes Knoerzer, Christian Fey Electronic image Rydberg states around segmented carbon nanotubes can be confined and shaped along the nanotube axis by engineering the image potential. We show how several such image states can be prepared simultaneously along the same nanotube. The inter-electronic distance can be controlled a priori by engineering tubes of specific geometries. High sensitivity to external electric and magnetic fields can be exploited to manipulate these states and their mutual long-range interactions. These building blocks provide access to a new kind of tailored long-range interacting quantum systems. [Preview Abstract] |
