Photonics

Nano-photonics is a rapidly growing and interdisciplinary field that requires the integration of nanotechnology, photonics, materials science, physics, chemistry, biology, and engineering. It offers great potential for scientific discoveries and technological innovation. The research in BINA focuses on optoelectronics and microelectronics, advancing imaging and sensing, and energy and environment. Our researchers enhance biological imaging, explore atomic-level magnetism for potential computing advancements, improve the performance and cost-effectiveness of solar cells, light-emitting diodes, and thermophotovoltaics, and provide new environmental monitoring, remediation, and catalysis methods.

    Nano-precision in the location of RNA molecules inside tissues is crucial for many biological processes including learning and
    memory. The multiplexed measurement of the nanoscale position of these molecules allows mapping the heterogeneity of
    complex tissues, and therefore can lead to a better understanding of many diseases including cancer.

  • Nano-scale crystallization phenomena

    Our group is developing approaches that utilize nano-scale systems for studies of crystallization phenomena and mechanisms that determine the morphologies of crystals. Insight from this research can lead to very useful technological applications, as understanding crystal growth mechanisms will allow us to better control crystalline products of chemical synthesis. This view is inspired by treating nano-crystals as “embryonic” stages of crystal growth. In a sense, every crystal begins its evolution as a nano-crystal. The huge advantage in studies that follow this perspective is in our ability to utilize extremely powerful electron microscopy methods, including a novel technique that allows us to perform high resolution electron microscopy directly in liquid solutions. In this way we can retrieve details of the crystal structure and overall shape at remarkable resolution, during the crystal’s initial formation. These details are often hidden in bulk crystals, unidentifiable by X-ray crystallography, yet critical for understanding of the mechanisms by which crystals grow.

  • Non-equilibrium quantum dynamics

    The negativity of the quasiprobabilities (shaded areas) and the violation of classical Inequality (yellow and green shaded area). Strong heat flows can only happen in the presence of negativities

    Progress in quantum technologies relies on understanding how quantum phenomena govern the dynamics of quantum systems far from equilibrium and on identifying the available quantum resources. This knowledge then allows us to manipulate the systems in order to obtain a desired outcome. Our group seeks to: (i) Develop dynamical descriptions that capture effects of quantum phenomena on the single-atom/molecule level and for systems far-from-equilibrium. (ii) Identify quantum resources and utilize them in controlling quantum transport processes and quantum state preparation. (iii) Thoroughly define the relationship between quantum effects and concepts from non-equilibrium thermodynamics.
