Correlated electron transport through parallel double-quantum-dot
Rong Lu, Zhi-Rong Liu, Guang-Ming Zhang
We investigate the spectral and transport properties of parallel double-quantum-dot (DQD) system with interdot tunneling coupling in both the equilibrium and nonequilibrium cases.…

Local quantum critical behavior in magnetic Kondo impurity models with partially screened moment
Guang-Ming Zhang, Lu Yu
In the strong coupling limit, an effective resonant level model is derived for the spin-1 underscreened Kondo impurity model. A local quantum critical behavior is induced by the fo…

Generalized Schwinger boson mean field theory for two-dimensional SU(4) symmetric spin-orbital antiferromagnet
Guang-Ming Zhang
A generalized Schwinger boson representation is proposed to describe the two-dimensional SU(4) symmetric spin-orbital quantum antiferromagnet. A uniform mean field solution gives r…
