Possible coexistence of superconductivity and static SDW stripes in the two-dimensional Hubbard model

The possibility of superconductivity coexisting in the stripe state of spin-density-wave (SDW) is studied by using the variational Monte Carlo method as the ground state of the under-doped two-dimensional (2D) Hubbard model. The model parameters are chosen for cuprate high- T c superconductors such...

Description
Summary:The possibility of superconductivity coexisting in the stripe state of spin-density-wave (SDW) is studied by using the variational Monte Carlo method as the ground state of the under-doped two-dimensional (2D) Hubbard model. The model parameters are chosen for cuprate high- T c superconductors such as La 2− x Sr x CuO 4 with x
