    • Title Physics Beyond the Standard Model with Polar Molecules
    • Abstract  Precision measurements in polar molecules are extremely sensitive probes of symmetry violating Physics Beyond the Standard Model.  These experiments are already exploring the TeV-scale in table-top experiments, and have many orders of magnitude of sensitivity remaining to be realized.  I will discuss some recent advances and ideas in the field that will extend these searches to the PeV-scale, as well as into sectors not currently probed with molecule experiments, such as the Hadronic sector.

    • Title  Manipulating Light Waves with Optical Metamaterials
    • Abstract  Nanostructured metals have provided us with a unique opportunity to manipulate light in an unconventional manner. Collectively, subwavelength metallic structures serve as building blocks for optical metamaterials with properties that were not observed or even speculated about in the past. This is a very exciting frontier in optics and materials science, with the promising goal of yielding better solar cells, faster computer chips, ultrasensitive biochemical detectors, and even invisible devices. While metamaterials are commonly viewed as artificially-structured media capable of realizing exotic electromagnetic properties, we can drive beyond this limited vision and explore the use of optical metamaterials as a generalizable platform for optoelectronic information technology. In this talk I will start with a general description of metamaterials in the conventional linear regime, include experimental demonstrations of the first magnetic metamaterial across the entire visible spectrum, and the world’s first negative-index material at optical frequencies. In the second half of the talk I will steer towards nonlinear light-matter interactions in optical metamaterials, including the electrically induced harmonic generation and optical rectification of light in a perfect metamaterial absorber, the nonlinear spectroscopy and imaging of a chiral metamaterial, and the backward phase-matching in an optical metamaterial where the fundamental and frequency-doubled waves possess opposite indices of refraction.

    • Title Studies of Hadron Structure and Dynamics with the PANDA Experiment at FAIR
    • Abstract  The PANDA (antiProton ANihilation in DArmstadt) collaboration at FAIR is a cooperation of more than 400 scientists from 19 countries. Its central goal is the elementary understanding of hadrons using the power of an antiproton beam. The vast difference in mass between the proton and its constituents is a manifestation of the importance of understanding the binding among quarks in the confinement regime. Exotic hadrons with their non- conventional structure, such as multi-quarks, hybrids, and glueballs will reveal uncharted properties of this binding. Proton form-factor measurements, deep virtual Compton scattering and the wide area of quark(-spin) dynamics as well as the behavior of hadrons inside nuclear media are significantly complementary aspects to understand the very nature of hadrons and are vital pieces of the experimental program of PANDA as well. Thus, open and hidden charm, lepton pairs and radiative channels, hidden strangeness and hyperons are commensurable probes to explore the imminent questions among bound states of QCD. The PANDA experiment features a modern multipurpose detector with excellent tracking, calorimetry and particle identification capabilities. Together with the high-quality antiproton beam at HESR, unprecedented annihilation rate, and sophisticated event filtering, it will be ideally suited to deliver decisive contributions to this field.

    • Title Quantum Error Correction:  
      Building a (Nearly) Perfect Quantum Computer from Imperfect Parts
    • Abstract 

      A revolution is underway in the construction of ‘artificial atoms’ out of superconducting electrical circuits.  These macroscopic ‘atoms’ have quantized energy levels and can emit and absorb quanta of light (in this case microwave photons), just like ordinary atoms. The large size of these ‘atoms’ yields remarkably strong atom-photon coupling and has given us the ability to completely control and measure the quantum state of the electromagnetic field in a cavity at the level of individual microwave photons.

      In particular, it is now possible to create record large ‘Schrödinger cat’ photon states and cats delocalized and entangled between two boxes.   In addition to being used to study quantum mechanics at macroscopic scales, these cat states form a novel but highly successful basis for quantum error correction in a ‘photonic’ quantum computer.  This talk will present an elementary introduction to the field as well as an overview of recent progress.
