Kavli Affiliate: Bruce A. Macintosh | First 5 Authors: Alexander Madurowicz, Bruce A. Macintosh, Jean-Baptiste Ruffio, Jeffery Chilcote, Vanessa P. Bailey | Summary: A semi analytic framework for simulating the effects of atmospheric seeing in Adaptive Optics systems on an 8-m telescope is developed with the intention of understanding the origin of the wind-butterfly, a […]

Kavli Affiliate: Kentaro Hori | First 5 Authors: Daichi Takane, Seigo Souma, Kosuke Nakayama, Takechika Nakamura, Hikaru Oinuma | Summary: We have performed angle-resolved photoemission spectroscopy of AlB2 which is isostructural to high-temperature superconductor MgB2. Using soft-x-ray photons, we accurately determined the three-dimensional bulk band structure and found a highly anisotropic Dirac-cone band at the […]
