Hybrid quantum devices, in which dissimilar quantum systems are combined in order to attain qualities not available with either system alone, may enable far-reaching control in quantum measurement, sensing, and information processing. A paradigmatic example is trapped ultracold atoms, which offer excellent quantum coherent properties, coupled to nanoscale solid-state systems, which allow for st...

Surface plasmon polaritons (SPPs) manipulation is of vital importance to construct ultracompact integrated micro/nano-optical devices and systems. Here we report the design, fabrication, and characterization of a SPP microcavity with full transverse and longitudinal mode selection and control on the surface of gold film. The designed microcavity supports the fundamental and first-order transver...

Microscale roughness on an otherwise smooth hydrophobic surface can significantly reduce the resistance to an external liquid flow. We study static drag reduction over a lubricantinfused surface by looking at an array of two-dimensional transverse grooves partially filled with a second immiscible fluid. Numerical simulations at separate length scales are used to probe the static drag reduction ...

All-optical plasmonic switches based on a novel coupled nano-disk cavity configuration containing nonlinear material are proposed and numerically investigated. The finite difference time domain simulation results reveal that the single-disk plasmonic structure can operate as an “on– off” switch with the presence/absence of pumping light. We also demonstrate that the proposed T-shaped plasmonic ...

Liquid droplet whispering-gallery-mode microresonators open a new research frontier for sensing, optomechanics and photonic devices. At visible wavelengths, where most liquids are transparent, a major contribution to a droplet optical quality factor is expected theoretically from thermal surface distortions and capillary waves. Here, we investigate experimentally these predictions using transie...

Theoretical analysis and Computer simulations have proven to be cost-effective and powerful tools in scientific studies of materials, particularly at nano-scale where synthesis of nano-structures, interpretation of their observed character and exploration of new structures are not always straight forward. We present here fundamental principles of techniques used today for computational simulati...

Nanoplastics are defined as plastic particles broken down to extremely small sizes (1–100 nm) with unknown effects the human body and immune system. Air food exposure scenarios involving blood, lungs intestine considered in literature. The fact that plastics also needs pass nose, oral cavity, throat is so far ignored tonsils immunologically important tissue cavity which ingested inhaled agents ...
