Origin of branch points in the spectrum of PT-symmetric periodic potentials
Ching-Hao Chang, Shi-Ming Wang, Tzay-Ming Hong
There exists multiple branch points in the energy spectrum for some \emph{PT}-symmetric periodic potentials, where the real eigenvalues turn into complex ones. By studying the tran…

Spin-glass-like behavior caused by Mn-rich Mn(Ga)As nanoclusters in GaAs
Ching-Hao Chang, T. M. Hong
We simulate the indirect exchange interaction between Mn-rich Mn(Ga)As nanoclusters in GaAs by analytical means. In contrast to the conventional Ruderman-Kittel-Kasuya-Yosida (RKKY…

Interlayer coupling enhanced by the interface roughness
Ching-Hao Chang, Tzay-Ming Hong
Previous experiment on Fe/Cr/Fe(001) trilayers reported a surprising observation that the interlayer exchange coupling could be enhanced drastically by the bombardment of irradiati…
