Spin Waves in Random Spin Chains
Xin Wan, Kun Yang, Chenggang Zhou +1
We study quantum spin-1/2 Heisenberg ferromagnetic chains with dilute, random antiferromagnetic impurity bonds with modified spin-wave theory. By describing thermal excitations in…

Spin Waves in Disordered III-V Diluted Magnetic Semiconductors
Mona Berciu, R. N. Bhatt
We propose a new scheme for numerically computing collective-mode spectra for large-size systems, using a reformulation of the Random Phase Approximation. In this study, we apply t…

Modified spin-wave study of random antiferromagnetic-ferromagnetic spin chains
Xin Wan, Kun Yang, R. N. Bhatt
We study the thermodynamics of one-dimensional quantum spin-1/2 Heisenberg ferromagnetic system with random antiferromagnetic impurity bonds. In the dilute impurity limit, we gener…
