Retraction: Quantum critical phenomena in the XY spin chain with the Dzyaloshinski-Moriyainteraction [Phys. Rev. A 79, 032338 (2009)]

摘要

We have recently found a flaw in the basic diagonalization results of the Hamiltonian presented in our paper. Since theseresults are critical to our paper, we wish to retract this paper to avoid misleading the readership. We regret the error.
