Xu Du: Two Dimensional Atomic Crystals

Two-dimensional atomic crystals, from graphene to various novel emerging systems such as layered transition metal dichalcogenides (MX2), hexagonal boron nitride, phosphorene, etc., have attracted great research interest in the past decade. At single- or few-atomic-layer thickness, these materials remain single crystalline under ambient conditions, making them ideal material systems for studying 2D mesoscopic physics. With controlling of thickness/dimensionality and lattice symmetry, their electronic structure may undergo significant transformation and hence new electrical, optical and magnetic properties can emerge, promising for novel device concepts and applications. In this talk Xu Du will give a general overview to the research on two dimensional atomic crystals, focusing on the lattice structure, mechanical and electrical properties of some of the typical materials. Xu Du will also discuss how 2D atomic crystals may be combined into heterostructures, which may host new physical phenomena and offer opportunities for novel device applications.

Xu Du is an Associate Professor and the leader of the Quantum Transport and Nanomaterials group at Stony Brook University. He received PhD from the University of Florida in 2004, and did his Postdoctoral study at Rutgers University. He joined the faculty of Department of Physics and Astronomy at Stony Brook University in 2009.

Navid Vafaei-Najafabadi: Miniaturizing Particle Accelerators-Plasma Style

Particle accelerators have been an invaluable tool for scientific discovery and research. While ever more energetic particles are needed to study the subatomic structure of matter, significant increase in the particle energies beyond those produced by the existing machines is not feasible due to their cost and scale. This is because the electric field used for accelerating particles is limited by the ionization and damage threshold of the physical structures. In contrast, a plasma, an ensemble of ions and electrons, is already an ionized medium and can support an accelerating force that is a 1000 times greater than those generated in conventional accelerators. In this talk, Dr. Vafaei-Najafabadi will discuss how plasma waves are used to accelerate particles - in particular electrons - and present recent experiments that demonstrate the advantages of using a plasma medium for electron acceleration, as well as some challenges that need to be overcome before plasma-based accelerators can become the foundation of next generation particle accelerators.

Navid Vafaei-Najafabadi has participated in the plasma-based electron acceleration research for nearly a decade and is an Assistant Professor at Stony Brook University. He received his PhD from UCLA in 2016, after which he joined the Physics and Astronomy Department at Stony Brook University.

Eden Figueroa: Building the Long Island Quantum Network

Public interest in quantum technology is fueled by the vision of a global quantum communication network. This realization will not only decisively change secure world-wide information transfer, but it will also provide a robust technological platform that can be translated to form the constituent elements of a universal quantum computer. In his talk, Dr. Eden Figueroa will discuss how to make low-cost, miniaturized room temperature quantum devices that will make such a quantum network practical and economically feasible. He will show the current progress towards building the first prototype of a quantum network that uses quantum light-matter interfaces to distribute flying photons and entanglement over several kilometers without detrimental losses, using satellite or local fiber links.

Eden Figueroa is an Assistant Professor and the leader of the Quantum Information Technology group at Stony Brook University. He received his PhD from the University of Calgary in 2008, and held an Alexander von Humboldt Postdoctoral position at the Max Planck Institute of Quantum Optics in Munich. He joined the Department of Physics and Astronomy at Stony Brook University in 2013.
