Hoffman, Anthony J., Sridhar, Aishwarya, Braun, Phillip X., Alekseyev, Leonid, Howard, Scott S., Franz, Kale J., Cheng, Liwei, Choa, Fow-Sen, Sivco, Deborah L, Podolskiy, Viktor A., Narimanov, Evgenii E., and Gmachl, Claire

Abstract:

We report on a novel class of semiconductor metamaterials that employ a strongly anisotropic dielectric function to achieve negative refraction in the midinfrared region of the spectrum, ~8.5–13 μm. We present two types of metamaterials, layered highly doped/undoped heterostructures and quantum well superlattices that are highly anisotropic. Contrary to other...

Vailulu’u Seamount, Samoa: Life and death on an active submarine volcano

Creator:

Staudigel, Hubert, Hart, Stanley R., Pile, Adele, Bailey, Bradley E., Baker, Edward T., Brooke, Sandra, Connelly, Douglas P., Haucke, Lisa, German, Christopher R., Hudson, Ian, Daniel Jones, Koppers, Anthony A.

Abstract:

Submersible exploration of the Samoan hotspot revealed a new, 300-m-tall, volcanic cone, named Nafanua, in the summit crater of Vailulu’u seamount. Nafanua grew from the 1,000-m-deep crater floor in <4 years and could reach the sea surface within decades. Vents fill Vailulu’u crater with a thick suspension of particulates and...
