Quantum Criticality in Dimerized Spin Ladders
Gennady Y. Chitov, Brandon W. Ramakko, Mohamed Azzouz
We analyze a possibility of quantum criticality (gaplessness) in dimerized antiferromagnetic two- and three-leg spin-1/2 ladders. Contrary to earlier studies of these models, we ex…
Systematic study of trace radioactive impurities in candidate construction materials for EXO-200
D. S. Leonard, P. Grinberg, P. Weber +54
The Enriched Xenon Observatory (EXO) will search for double beta decays of 136Xe. We report the results of a systematic study of trace concentrations of radioactive impurities in a…
A linear RFQ ion trap for the Enriched Xenon Observatory
B. Flatt, M. Green, J. Wodin +39
The design, construction, and performance of a linear radio-frequency ion trap (RFQ) intended for use in the Enriched Xenon Observatory (EXO) are described. EXO aims to detect the…
Effect of temperature on quantum criticality in the frustrated two-leg Heisenberg ladder
Brandon W. Ramakko, Mohamed Azzouz
The antiferromagnetic Heisenberg model on the two-leg ladder with exchange interactions along the chains, rungs, and diagonals is studied using the Jordan-Wigner transformation and…
