The surface states of topological insulators - Dirac fermion in curved two dimensional spaces
Dung-Hai Lee
The surface of a topological insulator is a closed two dimensional manifold. The surface states are described by the Dirac Hamiltonian in curved two dimensional spaces. For a slab-…
Localization of Metal-Induced Gap States at the Metal-Insulator Interface:Origin of Flux Noise in SQUIDs and Superconducting Qubits
SangKook Choi, Dung-Hai Lee, Steven G. Louie +1
The origin of magnetic flux noise in Superconducting Quantum Interference Devices with a power spectrum scaling as ( is frequency) has been a puzzle for over 20 years. Thi…
Field-induced Kosterlitz-Thouless transition in the N=0 Landau level of graphene
Kentaro Nomura, Shinsei Ryu, Dung-Hai Lee
At the charge neutral point, graphene exhibits a very unusual high resistance metallic state and a transition to a complete insulating phase in a strong magnetic field. We propose…
Antiferromagnetically Driven Electronic Correlation in Iron Pnictides and Cuprates
Hui Zhai, Fa Wang, Dung-Hai Lee
The iron pnictides and the cuprates represent two families of materials, where strong antiferromagnetic correlation drives three other distinct ordering tendencies: (1) superconduc…
The quantum valley Hall effect in proximity-induced superconducting graphene: an experimental window for deconfined quantum criticality
Pouyan Ghaemi, Shinsei Ryu, Dung-Hai Lee
We argue that by inducing superconductivity in graphene via the proximity effect, it is possible to observes the "quantum valley Hall effect". In the presence of magnetic field, su…
