Spin superconductor in ferromagnetic graphene
Qing-feng Sun, Zhao-tan Jiang, Yue Yu +1
We show a spin superconductor (SSC) in ferromagnetic graphene as the counterpart to the charge superconductor, in which a spin-polarized electron-hole pair plays the role of the sp…
The scaling feature of the magnetic field induced Kondo-peak splittings
Hui Zhang, X. C. Xie, Qing-feng Sun
By using the full density matrix approach to spectral functions within the numerical renormalization group method, we present a detailed study of the magnetic field induced splitti…
Quantum tunneling through planar p-n junctions in HgTe quantum wells
L. B. Zhang, Kai Chang, X. C. Xie +2
We demonstrate that a p-n junction created electrically in HgTe quantum wells with inverted band-structure exhibits interesting intraband and interband tunneling processes. We find…
Reply to the comment on "Do intradot electron-electron interactions induce dephasing?"
Zhao-tan Jiang, Qing-feng Sun, X. C. Xie +1
In the comment by Konig, Gefen, and Silva, their main point is to question the approximation we used in solving the Green's function. They believe that this approximative method is…
Metal-insulator transition in a multilayer system with a strong magnetic field
X. R. Wang, C. Y. Wong, X. C. Xie
We study the Anderson localization in a weakly coupled multilayer system with a strong magnetic field perpendicular to the layers. The phase diagram of 1/3 flux quanta per plaquett…
The level shifting induced negative magnetoresistance in the nearest-neighbor hopping conduction
X. R. Wang, S. C. Ma, X. C. Xie
We propose a new mechanism of negative magnetoresistance in non-magnetic granular materials in which electron transport is dominated by hopping between two nearest-neighbor cluster…
First principles theory of inelastic currents in a scanning tunneling microscope
K. Stokbro, Ben Yu-Kuang Hu, C. Thirstrup +1
A first principles theory of inelastic tunneling between a model probe tip and an atom adsorbed on a surface is presented, extending the elastic tunneling theory of Tersoff and Ham…
In-plane Magnetic Field Induced Kosterlitz-Thouless Type Metal Insulator Transition in Coupled Double Quantum Wells
D. Z. Liu, X. C. Xie
We study the localization properties in coupled double quantum wells with an in-plane magnetic field. The localization length is directly calculated using a transfer matrix techniq…
Study of Scaling in the Fractional Quantum Hall Effect
X. C. Xie, D. Z. Liu, J. K. Jain
In the composite fermion model of the fractional quantum Hall effect, composite fermions experience, in addition to the usual potential disorder, also a magnetic flux disorder. Mot…
Weak Field Phase Diagram for an Integer Quantum Hall Liquid
D. Z. Liu, X. C. Xie, Q. Niu
We study the localization properties in the transition from a two-dimensional electron gas at zero magnetic field into an integer quantum Hall (QH) liquid. By carrying out a direct…
