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…

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…

Application of the generalized 3D Jordan-Wigner transformation to the bilayer Heisenberg antiferromagnet
B. Bock, M. Azzouz
We extend the definition of the Jordan-Wigner transformation to three dimensions using the generalization of ideas that were used in the two-dimensional case by one of the present…
