Unconventional superconducting phases on a two-dimensional extended Hubbard model
Wen-Min Huang, Chen-Yen Lai, Chuntai Shi +1
We study the phase diagram of the extended Hubbard model on a two-dimensional square lattice, including on-site (U) and nearest-neighbor (V) interactions, at weak couplings. We sho…
Electronic structure of d-wave superconducting quantum wires
A. M. Bobkov, L. -Y. Zhu, S. -W. Tsai +3
We present analytical and numerical results for the electronic spectra of wires of a d-wave superconductor on a square lattice. The spectra of Andreev and other quasiparticle state…
Singular current response from isolated impurities in d-wave superconductors
Shan-Wen Tsai, P. J. Hirschfeld
The current response of a d-wave superconductor containing a single impurity is calculated and shown to be singular in the low-temperature limit, leading in the case of strong scat…
organic crystals: superconducting versus antiferromagnetic instabilities in an anisotropic triangular lattice Hubbard model
Shan-Wen Tsai, J. B. Marston
A Hubbard model at half-filling on an anisotropic triangular lattice has been proposed as the minimal model to describe conducting layers of organic materials. Th…
Weak-coupling functional renormalization-group analysis of the Hubbard model on the anisotropic triangular lattice
Shan-Wen Tsai, J. B. Marston
Motivated by experiments on the layered compounds -(BEDT-TTF)X, CsCuCl, and very recently NaCoOHO, we present a weak-coupling functional renormal…
