Emergence of massless Dirac quasiparticles in correlated hydrogenated graphene with broken sublattice symmetry
Kazuhiro Seki, Tomonori Shirakawa, Qinfang Zhang +2
Using the variational cluster approximation (VCA) and the cluster perturbation theory, we study the finite temperature phase diagram of a half-depleted periodic Anderson model on t…
Quantum confinement in perovskite oxide heterostructures: tight binding instead of nearly free electron picture
Zhicheng Zhong, Qinfang Zhang, Karsten Held
Most recently, orbital-selective quantum well states of electrons have been experimentally observed in SrVO ultrathin films [K. Yoshimatsu et. al., Science 333, 319 (2011)]…
Unexpected Anisotropic Two Dimensional Electron Gas at the LaAlO3/SrTiO3 (110) Interface
A. Annadi, X. Wang, K. Gopinadhan +17
The observation of a two dimensional electron gas (2DEG) (1, 2), superconductivity (3, 4), magnetic effects (5) and electronic phase separation (6-8) at the interfaces of insulatin…
Strain-engineered magnetic order in (LaMnO)/(SrMnO) superlattices
Qinfang Zhang, Shuai Dong, Baolin Wang +1
Using first-principles calculations based on the density functional theory, we show a strong strain dependence of magnetic order in (LaMnO)/(SrMnO) (001) sup…
