Magnetic Ordering in the Ising Antiferromagnetic Pyrochlore Nd 2 ScNbO 7

May 14, 2021
Author(s)
C. Mauws, N. Hiebert, M. Rutherford, H. D. Zhou, Q. Huang, M. B. Stone, Nicholas Butch, Y. Su, E. S. Choi, Z. Yamani, C. R. Wiebe
The question of structural disorder and its effects on magnetism is relevant to a number of spin liquid candidate materials. Although commonly thought of as a route to spin glass behavior, here we describe a system in which the structural disorder destroys

Targeted enrichment of 28Si thin films for quantum computing

March 9, 2020
Author(s)
Ke Tang, Hyun S. Kim, Aruna N. Ramanayaka, David S. Simons, Joshua M. Pomeroy
… computing remain unknown. Here we use hyperthermal energy ion beam deposition with silane gas to deposit epitaxial … parameters and measure the deposited film using secondary ion mass spectrometry (SIMS). The measured 29Si …

Enriching 28Si beyond 99.9998 % for semiconductor quantum computing

August 5, 2014
Author(s)
Kevin J. Dwyer, Joshua M. Pomeroy, David S. Simons, June W. Lau, Kristen L. Steffens
Using a laboratory-scale apparatus, we enrich 28Si and produce material with 40 times less residual 29Si than previously reported. Starting from natural abundance silane gas, we offer an alternative to industrial gas centrifuges for providing materials

99.996% 12C films enriched and deposited in situ

June 28, 2013
Author(s)
Kevin J. Dwyer, Joshua M. Pomeroy, David S. Simons
… A mass selected ion beam system is used to isotopically enrich and deposit … of the deposited films is assessed ex situ using Secondary Ion Mass Spectrometry. …

Adaptive Peak Fitting for Isotope Analysis via Atom Probe Mass Spectrometry

July 30, 2021
Author(s)
Frederick Meisenkothen, Daniel Samarov, Mark McLean, Irina Kalish, Eric B. Steel
… Since the peak forms can vary significantly between ion species and between data sets, no model peak form can be … method for assigning ions in the spectrum to specific ion species, as an alternative approach to the traditional ion ranging strategies. The goal is to produce an accurate, …

Ionization and appearance potentials in organic chemistry. 3. Determination of the difference between the enthalpies of formation of cis- and trans-isomers of bicyclo[4.3.0]- nonane and bicyclo[4.4.0]decane Using Appearance Potentials

June 1, 1980

Anzor I. Mikaia, Vladimir G. Zaikin
The first adiabatic potentials of the ionization of cis and trans iosmers with respect to the linkage of the rings of bicyclo[4.3.0]nonane and bicyclo[4.4.0]decane are practically identical. for the stereoisomers of these two series have been measured. The

Transient Phenoxyl Radicals: Formation and Properties in Aqueous Solutions

October 12, 2021
Author(s)
S Steenken, Pedatsur Neta
This chapter discusses the various methods of formation of phenoxyl radicals (oxidation of phenols by metal ions, by free radicals and radical cations, reaction of phenols with hydroxyl radicals, autoxidation of phenols, etc.) and the properties of

Quantum Dense Coding with Atomic Qubits

January 1, 2004
Author(s)
T Schaetz, Murray D. Barrett, Dietrich G. Leibfried, J Chiaverini, Joseph W. Britton, Wayne M. Itano, John D. Jost, Christopher Langer, David J. Wineland
We report the implementation of quantum dense coding on individual atomic qubits with the use of two trapped 9Be+ ions. The protocol is implemented with a complete Bell measurement that distinguishes the four operations used to encode two bits of classical
