Nature of the inhomogeneous state of the extended t-J model on a square lattice
Chung-Pin Chou, Ting-Kuo Lee
We carry out the variational Monte Carlo calculation to examine spatially inhomogeneous states in hole- and electron-doped cuprates. By using Gutzwiller approximation, we consider…
Topological insulator ribbon: Surface states and dynamical response
Lei Hao, Peter Thalmeier, T. K. Lee
We study theoretically the distributions of charge and spin polarization of a topological insulator ribbon, with a realistic rectangular cross section. Due to constriction in two l…
Grand-canonical variational approach for the t-J model
Chung-Pin Chou, Fan Yang, Ting-Kuo Lee
Gutzwiller-projected BCS wave function or the resonating-valence-bond (RVB) state in the 2D extended t-J model is investigated by using the variational Monte Carlo technique. We sh…
Enhanced Thermoelectric Power in Dual-Gated Bilayer Graphene
Chang-Ran Wang, Wen-Sen Lu, Lei Hao +5
Thermoelectric power of a material, typically governed by its band structure and carrier density, can be varied by chemical doping that is often restricted by solubility of the dop…
Surface spectral function in the superconducting state of a topological insulator
Lei Hao, T. K. Lee
We discuss the surface spectral function of superconductors realized from a topological insulator, such as the copper-intercalated BiSe. These functions are calculated…
