Two-dimensional pattern formation in surfactant-mediated epitaxial growth
Bang-Gui Liu, Jing Wu, E. G. Wang +1
The effects of a surfactant on two-dimensional pattern formation in epitaxial growth are explored theoretically using a simple model, in which an adatom becomes immobile only after…
The sublattice magnetizations of the spin-s quantum Heisenberg antiferromagnets
Bang-Gui Liu
We study the spin- quantum Heisenberg antiferromagnetic models in a magnon theory free of any unphysical magnon state. Because the unphysical magnon states are completely remove…
Accurate mapping of quantum Heisenberg magnetic models of spin on strong-coupling magnon systems
Bang-Gui Liu, Gerd Czycholl
An infinite- term is introduced into the Holstein-Primakoff-transformed magnon hamiltonian of quantum Heisenberg magnetic models of spin . This term removes the unphysical sp…
Infinite coupling magnon theory of quantum Heisenberg magnetic models of spin s
Bang-Gui Liu, Gerd Czycholl
An infinity magnon coupling term is introduced into the Holstein-Primakoff transformed forms of the Heisenberg ferromagnetic and antiferromagnetic models of any spin to rigorou…
