New Critical Compilations of Atomic Transition Probabilities

October 16, 2008
Author(s)
Wolfgang L. Wiese, Jeffrey R. Fuhr, Daniel E. Kelleher, Larissa Podobedova
At the National Institute of Standards and Technology (NIST), we are continuing our critical evaluation and compilation work on atomic transition probabilities. We have recently concentrated our efforts on the spectra of Na, Mg, Al, Si and S for all stages

New Generation of the NIST Atomic Spectroscopic Databases

January 3, 2005
Author(s)
Y Ralchenko, Jeffrey R. Fuhr, F C. Jou, Alexander Kramida, William C. Martin, Larissa Podobedova, Joseph Reader, E B. Salomon, Jean E. Sansonetti, Wolfgang L. Wiese
The latest advances in development of atomic spectroscopic databases at the National Institute of Standards and Technology (NIST) result from implementation of modern technologies in database management and database-user interaction. Here we report a

Few-electron highly charged muonic Ar atoms verified by electronic K xrays

Takuma Okumura, Toshiyuki Azuma, Douglas Bennett, W. Bertrand (Randy) Doriese, Malcolm Durkin, Joseph Fowler, Johnathon Gard, Tadashi Hashimoto, Ryota Hayakawa, Yuto Ichinohe, Paul Indelicato, Tadaaki Isobe, Sohtaro Kanda, Daiji Kato, Miho Katsuragawa, Naritoshi Kawamura, Yasushi Kino, Nao Kominato, Yasuhiro Miyake, Kelsey Morgan, Hirofumi Noda, Galen O'Neil, Shinji Okada, Kenichi Okutsu, Nancy Paul, Carl D. Reintsema, Toshiki Sato, Dan Schmidt, Kouichiro Shimomura, Patrick Strasser, Daniel Swetz, Tadayuki Takahashi, Shinichiro Takeda, Soshi Takeshita, Motonobu Tampo, Hideyuki Tatsuno, Tong Xiao-Min, Joel Ullom, Shin Watanabe, Shinya Yamada, Takuma Yamashita
Electronic K x rays emitted by muonic Ar atoms in the gas phase were observed using a superconducting transition-edge-sensor microcalorimeter. The high-precision energy spectra provided a clear signature of the presence of muonic atoms accompanied by a few

Quantum Critical Behavior in Ce(Fe 0.76 Ru 0.24 ) 2 Ge 2

May 7, 2019
Author(s)
Wouter Montfrooij, Tom Heitmann, Yiming Qiu, Shannon M. Watson, Ross Erwin, Wangchun Chen, Yang Zhao, Meigan Aronson, Yingkai Huang, Anne de Visser
Systems with embedded magnetic ions that exhibit a competition between magnetic order and disorder down to absolute zero can display unusual low temperature behaviors of the resistivity, hyperscaling behavior in which the relaxation back to equilibrium

Kitaev chains with long-range interactions

October 9, 2014
Author(s)
Davide Vodola, Luca Lepori, Elisa Ercolessi, Alexey Gorshkov, Guido Pupillo
We propose and analyze a generalization of the Kitaev chain for fermions with long-range p-wave pairing, which decays with distance as a power-law with exponent $\alpha$. Using the integrability of the model, we demonstrate the existence of two types of

Temperature sculpting in yoctoliter volumes

February 14, 2013
Author(s)
Joseph E. Reiner, Joseph W. Robertson, Daniel L. Burden, Lisa K. Burden, Arvind Balijepalli, John J. Kasianowicz
… nanoparticles adjacent to a single nanometer-scale protein ion channel. Visible laser light incident on the …

Rate Constants for Reactions of Phenoxyl Radicals in Solution

March 1, 2005
Author(s)
Pedatsur Neta, J Grodkowski
Absolute rate constants for reactions of phenoxyl radicals in solution have been compiled and evaluated from the literature. Rate constants are included for phenoxyl radicals bearing various substituents, including semiquinone radicals and radical ions, as
