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…
Giant switchable Rashba effect in oxide heterostructures
Zhicheng Zhong, Liang Si, Qinfang Zhang +3
One of the most fundamental phenomena and a reminder of the electron's relativistic nature is the Rashba spin splitting for broken inversion symmetry. Usually this splitting is a 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)]…
Magnetic and Orbital Order in (MnO)/(MnO) Superlattices Studied via a Double-Exchange Model with Strain
Shuai Dong, Qinfang Zhang, Seiji Yunoki +2
The two-orbital double-exchange model is employed for the study of the magnetic and orbital orders in (MnO)/(MnO) (: rare earths; : alkaline earths)…
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…
Large spectral weight transfer in optical conductivity of SrTiO induced by intrinsic vacancies
Teguh C. Asmara, Xiao Wang, Iman Santoso +11
The optical conductivity () of SrTiO for various vacancies has been systematically studied using a combination of ultraviolet - vacuum ultraviolet (UV-VUV) reflectivit…
Ab Initio Study of the Intrinsic Exchange Bias at the SrRuO/SrMnO Interface
Shuai Dong, Qinfang Zhang, Seiji Yunoki +2
In a recent publication (S. Dong et al., Phys. Rev. Lett.103, 127201 (2009)), two (related) mechanisms were proposed to understand the intrinsic exchange bias present in oxides het…
First-principles study of the spin-mixing conductance in Pt/NiFe junctions
Qinfang Zhang, Shin-ichi Hikino, Seiji Yunoki
Based on the spin-pumping theory and first-principles calculations, the spin-mixing conductance (SMC) is theoretically studied for Pt/Permalloy (NiFe, Py) junctions.…
Multiferroic Properties of CaMnO
Guoquan Zhang, Shuai Dong, Zhibo Yan +5
We report that CaMnO is a new magnetic multiferroic material. The appearance of a ferroelectric polarization coinciding with the magnetic phase transition ( K) s…
