Disorder-Induced Excitation Continuum in a Spin-1/2 Cobaltate on a Triangular Lattice

July 31, 2023
Author(s)
Bin Gao, Tong Chen, Chien-Lung Huang, Yiming Qiu, Guangyong Xu, Jesse Liebman, Lebing Chen, Matthew B. Stone, Erxi Feng, Huibo Cao, Xiaoping Wang, Xianghan Xu, Sang-Wook Cheong, Stephen Winter, Pengcheng Dai
A spin-1/2 triangular-lattice antiferromagnet is a prototypical frustrated quantum magnet, which exhibits remarkable quantum many-body effects that arise from the synergy between geometric spin frustration and quantum fluctuations. It can host quantum

Field-Tunable Quantum Disordered Ground State in the Triangular-Lattice Antiferromagnet NaYbO 2

October 1, 2019
Author(s)
Mitchell M. Bordelon, Eric Kenney, Chunxiao Liu, Tom Hogan, Lorenzo Posthuma, Marzieh Kavand, Yuangqi Lyu, Mark Sherwin, Nicholas Butch, Craig Brown, M. J. Graf, Leon Balents, Stephen D. Wilson
One of the simplest routes to pursuing magnets with strong quantum fluctuations that quench conventional order is via decorating a triangular lattice with antiferromagnetically coupled S=1/2 moments. As disorder and anisotropies inherent in materials

Fluid Transport in High-Volume Fly Ash Mixtures with and without Internal Curing

October 7, 2013
Author(s)
Igor de la Varga, Robert Spragg, Carmelo di Bella, Javier Castro, Dale P. Bentz, Jason Weiss
The transport of fluid and ions in concrete mixtures is central to many aspects of concrete deterioration. As a result, transport properties are frequently measured as an indication of the durability that a concrete mixture may be expected to have. This

Myocardial Calcification in Captive Grouper Epinephelus Aeneus

June 1, 2009
Author(s)
Naomi Eidelman, A Colorni, Jirun Sun, M.C. Fishbein, A Diamant
A case of myocardial calcification is described in the Mediterranean white grouper, Epinephelus aeneus, cultured as broodstock in Eilat (Israel, Red Sea). Large calcified nodules and scar tissue were observed in the ventricular tissues. The chemical

Glass Pocket Evolution in Vitreous Bonded Sapphire

October 16, 2008
Author(s)
Jong S. Lee, M K. Kang, Sheldon M. Wiederhorn, B Hockey, J Blendell
This paper discusses the evolution of glass filled pockets formed by the growth of sapphire through polycrystalline aluminum oxide bonded by anorthite glass. During growth, excess glass is entrapped within the sapphire as channels, which, upon annealing

Particle Growth in Silane RF Discharges

October 16, 2008
Author(s)
Alan Gallagher
Calculations and measurements of particle growth in silane RF capacitively coupled discharges are reported. The measurements of particle diameters of 8 nm to 50 nm. This particle growth is typically 50 times as fast as film growth, and measured density
