D-wave bosonic pair in an optical lattice
Zi Cai, Lei Wang, Jian Li +3
We present a bosonic model, in which two bosons may form a bound pair with d-wave symmetry via the four-site ring exchange interaction. A d-wave pairing superfluid as well as a d-w…
In-plane noncollinear exchange coupling mediated by helical edge states in Quantum Spin Hall system
Jinhua Gao, Weiqiang Chen, X. C. Xie +1
We study the Ruderman-Kittel-Kasuya-Yoshida (RKKY) interaction mediated by helical edge states in quantum spin hall system. The helical edge states induce an in-plane noncollinear…
Numerical study of the topological Anderson insulator in HgTe/CdTe quantum wells
Hua Jiang, Lei Wang, Qing-feng Sun +1
We study the disorder effect on the transport properties in the HgTe/CdTe semiconductor quantum wells. We confirm that at a moderate disorder strength, the initially un-quantized t…
The electric current induced heat generation in a strongly interacting quantum dot in the Coulomb blockade regime
Jie Liu, Juntao Song, Qing-feng Sun +1
The heat generation by an electric current flowing through a quantum dot with the dot containing both electron-electron interaction and electron-phonon interaction, is studied. Usi…
Scanning tunneling spectroscopy of a magnetic atom on graphene in the Kondo regime
Huai-Bin Zhuang, Qing-feng Sun, X. C. Xie
The Kondo effect in the system consisting of a magnetic adatom on the graphene is studied. By using the non-equilibrium Green function method with the slave-boson mean field approx…
