Prospects of a Pb$^2+}$ ion clock

Author(s)
Kyle Beloy
We propose a high-performance atomic clock based on the 1.81 PHz transition between the ground and first-excited state of doubly ionized lead. Utilizing an even...

Freezing of a Disorder Induced Spin Liquid with Strong Quantum Fluctuations

Author(s)
Xiao Hu, Daniel M. Pajerowski, Depei Zhang, Andrey Podlesnyak, Yiming Qiu, Qing Huang, Haidong Zhou, Israel Klich, Alexander I. Kolesnikov, M. B. Stone, Seung-Hun Lee
Sr 2CuTe 0.5W 0.5O 6 is a square-lattice magnet with super-exchange between S = 1/2 Cu 2+ spins mediated by randomly distributed Te and W ions. Here, using sub...

Quantum harmonic oscillator spectrum analyzers

Author(s)
Jonas Keller, Panyu Hou, Katherine C. McCormick, Daniel Cole, Stephen Erickson, Jenny Wu, Andrew C. Wilson, Dietrich Leibfried
Characterization and suppression of noise are essential for the control of harmonic oscillators in the quantum regime. We measure the noise spectrum of a...

A Decade of Reoccurring Software Weaknesses

Author(s)
Assane Gueye, Carlos Galhardo, Irena Bojanova, Peter Mell
The Common Weakness Enumeration (CWE) community publishes an aggregate metric to calculate the 'Most Dangerous Software Errors.' However, the used equation...

DNA glycosylase deficiency leads to decreased severity of lupus in the Polb-Y265C mouse model

Author(s)
Sesha Paluri, Matthew Burak, Alireza Senenjani, Kelly Carufe, Kaylin Clairmont, Isabel Alvarado-Cruz, Rithy Meas, Michael Kashgarian, Caroline Zeiss, Stephen Maher, Alfred Bothwell, Erdem Coskun, Melis Kant, Pawel Jaruga, Miral M. Dizdar, R S. Lloyd, Joann B. Sweasy
The Polb gene encodes DNA polymerase beta (Pol β), a DNA polymerase that functions in base excision repair (BER) and microhomology-mediated end-joining. The Pol...

Atomic Dynamics of Metallic Glass Melts La50Ni15Al35 and Ce70Cu19Al11 Studied by Quasielastic Neutron Scattering

Author(s)
Peng Luo, Abhishek Jaiswal, Yanqin Zhai, Zhikun Cai, Nathan P. Walter, Long Zhou, Dawei Ding, Ming Liu, Rebecca Mills, Andrey Podlesnyak, Georg Ehlers, Antonio Faraone, Haiyang Bai, Weihua Wang, Y. Z.
By employing quasi-elastic neutron scattering, we studied the atomic-scale relaxation dynamics and transport mechanism of La 50Ni 15Al 35 and Ce 69Cu 20Al 10Nb...

A Large Beam High Efficiency Radio Frequency Neutron Spin Flipper

Author(s)
Wangchun Chen, Ross W. Erwin, Peter Tsai, Md. T. Hassan, Nancy Hadad, Charles F. Majkrzak
A design for a radio-frequency (RF) neutron spin flipper obtained from magneto-static and neutron spin transport simulations is presented. The RF flipper...

Origin and control of ionic hydration patterns in nanopores

Author(s)
Miraslau L. Barabash, William A. Gibby, Carlo Guardiani, Alexander Smolyanitsky, Dmitry G. Luchinsky, Peter V. McClintock
In order to permeate a nanopore, an ion must overcome a dehydration energy barrier caused by the redistribution of surrounding water molecules. The...
