Measurement of Λ Polarization in the π ¯ p → K 0 Λ Reaction at p π¯ = 1.33 GeV/ c toward a New Λ p Scattering Experiment

T. Sakao, Koji Miwa, J. K. Ahn, Y. Akazawa et autres

Abstract Understanding the spectrum and dynamics of excited nucleon states ($N^{*}$ resonances) remains a central challenge in hadron physics, as these resonances emerge in intermediate states of $\pi N$ and $\gamma N$ interactions. The dynamical coupled-channel models addressing this problem rely critically …

Enhanced Second Harmonic Generation of NLO Polymer/Plasmonic Au Nanoprism Hybrid Structure

Atsushi Sugita, Kazuki Kuroyanagi, Kei Hosomi, Masayoshi Kamiya

Strong and confined localized surface plasmon (LSP) enhanced optical fields are useful to enhance various light-matter interactions at the nanoscale. One of the most important applications is nonlinear optics (NLO), mixing of multiple light waves. Due to the limited light-matter interaction length …

Enhanced SHG Behavior of Plasmonic Metal Nanostructure Coated with Poled NLO Polymer

Atsushi Sugita, Kazuki Kuroyanagi, Kohei Sato, Kei Hosomi et autres

We propose a strategy using a poled NLO polymer to further enhance the SP-enhanced SHG conversion of plasmonic nanostructures. A 300-fold increase in SHG conversion efficiency is achieved by coating Au nanostructures with this material.

Non-invasive nanoscale imaging of protein micro- and nanocrystals for screening crystallization conditions

Krishna Prasad Khakurel, Kei Hosomi, Wataru Inami, Yoshimasa Kawata

Crystallography has been the routine technique for studying high-resolution structures of proteins for over five decades. A major bottleneck in structure determination of macromolecules is obtaining crystals of a size and quality suitable for single-crystal X-ray crystallography experiments. Many challenging proteins either …

Development of a localized surface plasmon–enhanced electron beam–pumped nanoscale light source for electron beam excitation–assisted optical microscopy

Atsushi Nakamura, Shunpei Shiba, Kei Hosomi, Atsushi Ono et autres

We have demonstrated localized surface plasmon (LSP)-enhanced cathodoluminescence (CL) from an atomic layer deposition-grown Al2O3/ZnO/Al2O3 heterostructure to develop a bright nanometer-scale light source for an electron beam excitation-assisted optical microscope. Three types of metals, Ag, Al and Au, were compared, and an …
