Growth of quantum well films of topological insulator Bi2Se3 on insulating substrate
Cui-Zu Chang, Ke He, Min-Hao Liu +6
Insulating substrates are crucial for electrical transport study and room temperature application of topological insulator films at thickness of only several nanometers. High quali…
Electron interaction-driven insulating ground state in Bi2Se3 topological insulators in the two dimensional limit
Minhao Liu, Cui-Zu Chang, Zuocheng Zhang +10
We report a transport study of ultrathin Bi2Se3 topological insulators with thickness from one quintuple layer to six quintuple layers grown by molecular beam epitaxy. At low tempe…
Particle-hole symmetry and interaction effects in the Kane-Mele-Hubbard model
Dong Zheng, Guang-Ming Zhang, Congjun Wu
We prove that the Kane-Mele-Hubbard model with purely imaginary next-nearest-neighbor hoppings has a particle-hole symmetry at half-filling. Such a symmetry has interesting consequ…
Quasiparticle interference of C2-symmetric surface states in LaOFeAs parent compound
Xiaodong Zhou, Cun Ye, Peng Cai +3
We present scanning tunneling microscopy studies of the LaOFeAs parent compound of iron pnictide superconductors. Topographic imaging reveals two types of atomically flat surfaces,…
Coexistence of multi-photon processes and longitudinal couplings in superconducting flux qubits
Yu-xi Liu, Cheng-Xi Yang, Hui-Chen Sun +1
In contrast to natural atoms, the potential energies for superconducting flux qubit (SFQ) circuits can be artificially controlled. When the inversion symmetry of the potential ener…
