Atomic layer etching of niobium nitride using sequential exposures of O$_2$ and H$_2$/SF$_6$ plasmas

Posted by dbos February 25, 2025Caltech

Kavli Affiliate: Austin J. Minnich | First 5 Authors: Azmain A. Hossain, Sela Murphy, David S. Catherall, Anthony J. Ardizzi, Austin J. Minnich | Summary: Niobium nitride (NbN) is a metallic superconductor that is widely used for superconducting electronics due to its high transition temperature ($T_c$) and kinetic inductance. Processing-induced damage negatively affects the performance […]

Directional propagation of quantum Hall viscous fluid by nano-structural engineering

Posted by dbos February 24, 2025UCAS

Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Hiroshi Funaki, Ai Yamakage, Ryotaro Sano, Mamoru Matsuo, | Summary: We present a microscopic theory of the viscous electron fluid in the quantum Hall state based on the nonequilibrium Green’s function method and the von Neumann lattice representation. This approach permits the formulation of hydrodynamic equations in […]

Are Sparse Autoencoders Useful? A Case Study in Sparse Probing

Posted by dbos February 23, 2025MIT

Kavli Affiliate: Max Tegmark | First 5 Authors: Subhash Kantamneni, Joshua Engels, Senthooran Rajamanoharan, Max Tegmark, Neel Nanda | Summary: Sparse autoencoders (SAEs) are a popular method for interpreting concepts represented in large language model (LLM) activations. However, there is a lack of evidence regarding the validity of their interpretations due to the lack of […]
