Scanning Ion Microscopy with Low Energy Lithium Ions

Author(s)
Kevin A. Twedt, Lei Chen, Jabez J. McClelland
Using an ion source based on photoionization of laser-cooled lithium atoms, we have developed a scanning ion microscope with probe sizes of a few tens of

Microresonator frequency comb optical clock

Scott B. Papp, Katja M. Beha, Pascal P. Del'Haye, Franklyn J. Quinlan, Hansuek Lee, Kerry J. Vahala, Scott A. Diddams
Optical frequency combs enable measurement precision at the 20th digit, and measurement accuracy entirely commensurate with their reference oscillator. A new

Final report of the key comparison CCQM-K98: Pb isotope amount ratios in bronze

Author(s)
Jochen Vogl, Yong-Hyeon Yim, Kyoung-Seok Lee, Heidi Goenaga-Infante, Dmitriy Malinowskiy, Tongxiang Ren, Jun Wang, Robert D. Vocke Jr., Karen E. Murphy, Naoko Nonose, Olaf Rienitz, Janine Noordmann, Teemu Naeykki, Timo Sara-Aho, Bet¿l Ari, Oktay Cankur
Isotope amount ratios are proving useful in an ever increasing array of applications that range from studies unravelling transport processes, to pinpointing the

Permanents, alpha-permanents and Sinkhorn balancing

Author(s)
F Sullivan, Isabel M. Beichl
The method of Sinkhorn balancing that starts with a non-negative square matrix and iterates to produce a related doubly stochastic matrix has been used with

Synthesis, transport properties, and electronic structure of Cu2CdSnTe4

Author(s)
Yongkwan Dong, Artem R. Khabibullin, Kaya Wei, Zhen-Hua Ge, Joshua Martin, James Salvador, Lilia Woods, George S. Nolas
A new stannite phase was synthesized and its temperature dependent transport properties were investigated. It is found that the electrical resistivity increases

A classical channel model for gravitational decoherence

Author(s)
Jacob M. Taylor, Dvir Kafri, G J. Milburn
We show that, by treating the gravitational interaction between two mechanical resonators as a classical measurement channel, a gravitational decoherence model
