Ferromagnetism of GaMnAs and Weiss theory of Curie temperature in the coherent potential approximation
Sze-Shiang Feng, Mogus Mochena
The zinc-blende GaAs-based III-V diluted magnetic semiconductors (DMS)are studied in the coherent potential approximation(CPA). In this work, we use the exact Hilbert transformatio…
Ground-state properties and molecular theory of Curie temperature in the coherent potential approximation of diluted magnetic semiconductors
Sze-Shiang Feng, Mogus Mochena
Using spin-1/2 description of valence holes and Kondo coupling between local spins and carriers, GaAs-based III-V diluted magnetic semiconductors (DMS)are studied in the coherent p…
Spin-wave softening and Hund's coupling in ferromagnetic manganites
Sze-Shiang Feng, Mogus Mochena
Using one-orbital model of hole-doped manganites, we show with the help of Holstein-Primakov transformation that finite Hund's coupling is responsible for the spin-wave softening i…
Conformal Field Theory Correlators From sine-Gordon Model on AdS Spacetime
Sze-Shiang Feng, Mu-Lin Yan
Using the proposed AdS/CFT correspondence, we calculate the correlators of operators of conformal field theory at the boundary of AdS corresponding to the sine-Gordon model…
Conservative Currents of Boundary Charges in Gravity
Sze-Shiang Feng, Bin Wang, Xin-He Meng
The boundary charges which constitute the Virasoro algebra in 2+1 dimensional anti-de Sitter gravity are derived by way of Noether theorem and diffeomorphic invariance. It shows th…
SU(2) Charges as Angular-momentum in N=1 Self-dual Supergravity
Sze-Shiang Feng, Zi-Xiang Wang, Xi-Jun Qiu
The N=1 self-dual supergravity has SL(2.C) symmetry. This symmetry results in SU(2) charges as the angular-momentum. As in the non-supersymmetric self-dual gravity, the currents ar…
